Unsurprisingly, COVID-19 has taken its toll on the Fastener Industry.

Some of the reported effects are given below.

The seasonally adjusted Fastener Distributor Index (FDI) for March was 44.4, deteriorating rapidly as the COVID-19 pandemic and ensuing shutdowns took hold. Sales trends on a seasonally adjusted basis were much weaker. The six-month outlook was revised sharply lower, which along with lower employment levels pushed the Forward-Looking Indicator (FLI) down to the lowest reading in survey history. In response to this month’s supplemental question on the impacts of the economic shutdown, respondents were roughly evenly split on whether economic trends will deteriorate further from here or return to previous levels, although the percentage expecting lower activity over the next six months surged (73% vs. 32% in February).

It’s a universal fact that Fasteners play a key role in almost every industry be it Heavy metal industry, Iron and steel industry or else. Moreover, just like every technology, the Fastening technology has also evolved big time in the past few years.

Many of the recent innovations in fastening technology owe much to marketplace directives for smaller and lighter packages produced quickly and cost-effectively. These demands dictate that fasteners work harder, “smarter,” and in more ways to advance product design and development. As a result and in a notable departure from the past, designers now will more likely consider and specify attaching hardware as “first thought” instead of afterthought.

For the fastening industry the outcome is that the drawing board (and computer screen) is rarely blank. Participating as active design partner (a trend in itself), leading manufacturers recognize a need to keep pace with evolving applications, giving rise to the next generation of products and fostering entirely new assembly solutions.

Screw Design Innovation

There has been a tremendous advance in the thread design of self-threading screws.

With milling ribs facilitating self-countersinking, fiber cut tips for stress-free driving into wood, EXPANDET screws have advanced technology for screw fixings in wood construction.

Innovation in the thread profiles are now producing screws that speed up stress-free fixing in plastics.

 

 

A key trend is evidenced by an expanding category of fasteners offering specific functional permanence. These types can be installed permanently and then mated with minimal loose hardware to complete attachment. They replace traditional permanent joining methods, such as adhesives, rivets, and welding, which inherently disallow component disassembly.

Their primary benefit is in providing the means for components to be attached securely while enabling subsequent removal, whether for service or replacement. In short, attachment is “permanent” until or unless otherwise required.

With some projects, finding a fastener that works with thin or brittle materials can seem impossible. This is where rivet nuts, which are also known as a blind nuts, blind rivet nuts, or threaded inserts, come in.

Security Trends

The need to safeguard against theft and vandalism in now becoming an essential part of design specifications.

Security Screws are certainly a worthwhile consideration in not just preventing theft, but also for manufacturers to prevent unwanted tampering of their products. This has spurred a number of security fastening solutions for a number of applications.

JOINING TECHNIQUES FOR PLASTICS

Many of the recent innovations in fastening technology owe much to marketplace directives for smaller and lighter packages produced quickly and cost-effectively. These demands dictate that fasteners work harder, “smarter,” and in more ways to advance product design and development. As a result and in a notable departure from the past, designers now will more likely consider and specify attaching hardware as “first thought” instead of afterthought.

As a natural result of these innovations, utilization of plastic materials in engineering structures has increased because of benefits accruing from their low weight, high specific strength and elastic modulus, design flexibility, and reduced manufacturing

Sometimes you will have to assemble two or more component parts to produce a complex part. Early in the development stage, designers need to consider how they will effectively join mating components into a functional unit. Joining techniques can offer a cost-effective, aesthetically pleasing, and structurally sound solution for designing and manufacturing intricate parts.

Some of the joining techniques are enumerated below.

MECHANICAL FASTENING

Mechanical fasteners — screws, bolts and rivets — offer one of the least expensive, most reliable and commonly used joining methods for assemblies that must be taken apart a number of times.

When using common mechanical methods for securing parts, pay special attention to the fastener’s head.

Countersunk heads produce undesirable tensile stress in the mating parts and should be avoided.

 

Bolt or screw heads that have a flat underside, called Pan or Cheese head, produce less harmful, compressive stress and are to be preferred.

 

 

Use flat washers under both nut and fastener heads because these help distribute the assembly force over larger areas.

Ensure that there is sufficient distance between the edge of the fastener’s hole and the part’s edge. As a rule of thumb, this distance should be at least the diameter of the hole or twice the part’s thickness, whichever is greater.

Anchor bolts are used extensively in concrete, brick and block masonry and cavities to make structural attachments and connections. To date, a limited amount of information has been available to aid designers and users in the selection and design of anchor bolts in various types of substrates.

In new masonry construction, anchor bolts were commonly embedded in walls and columns to support beams, plates and ledgers. However, for flexibility and ease of construction, the use of post-installed anchors is increasing.

Post-installed anchor bolt systems

In prefabricated panel construction, anchor bolts are used to facilitate connections to the structural frame.

Renovation and rehabilitation of existing masonry structures usually require that anchor bolts be used to attach stair risers, elevator tracks and various frame assemblages for equipment installation.

This is only a fraction of the possible uses of anchor bolts in masonry construction and with the increase of new, innovative architectural masonry designs, the uses of anchor bolts in masonry construction are likely to increase.

Anchors can be divided into two generic categories: Expansion-type anchors and Adhesive or Chemical-type anchors.

Expansion Anchors.

(a) Torque-controlled expansion anchors

Sleeve anchors develop their strength by the expansion of a cylindrical metal sleeve or shield into the base material as the bolt is tightened.

The expansion of the sleeve along the length of the anchor provides a larger bearing surface than the wedge anchor, and is recommended for use in brick masonry

Wedge anchors develop their hold by means of a wedge or wedges that are forced into the base material when the bolt is tightened.

The wedges create large point bearing stresses within the hole

Drop in Anchors are produced to allow shallow embedment depths and are expanded or set by an impact setting tool.

These are extremely suitable for installations into roof slabs. As the combination of shallow embedment and high stresses imparted by the expansion tend to cause cracking or splitting in masonry, they are not recommended for use in brick.

(b) Concrete screw

Concrete screws are screwed into pre-drilled holes by a special screwdriver – TORX DRIVE

The threads will cut into the concrete and create mechanical interlock between screw and concrete. This is an expansion free fixing.

The need to safeguard against theft and vandalism in now becoming an essential part of design specifications.

Increasingly in this competitive world, public and private property has become highly vulnerable to tampering, vandalism and theft.

This creates a number of undesirable consequences.

 

Impact of Theft and Tampering.

• Pliferage of Goods
• Vandalism – Destruction of valuable property.
• Lost revenue due to pilferage
• Liability claims due to tampered equipment.
• Damage to Reputation of the firm because of equipment downtime.
• Breakdowns leading to downtime and loss of productivity.
• High Maintenance costs for tampered parts.
• Negative impact on public safety due to vandalised public amenities.

One way to minimise or eliminate theft, tampering and vandalism is to use Security Fastening solutions.

 

Security fasteners are specially designed fasteners which cannot be removed using standard screwdrivers or spanners thus preventing theft, vandalism and tampering by unauthorised individuals. Virtually every industry, from retail stores to governmental security has issues with theft, loss prevention and vandalism.

Security Screws are certainly a worthwhile consideration in not just preventing theft, but also for manufacturers to prevent unwanted tampering of their products.

It’s likely that you’ve seen various iterations of the following message featured in product instruction manuals or even on products themselves: “Do not attempt to take this product apart, ensure that a qualified professional is sought”. This particularly features in electrical products where opening up the product could result in electric shock.

The use of security screws would be ideal in such instances by manufacturers of products ensuring that it is made difficult for an end user to take the product apart.

Similarly, furniture manufacturers may wish to prevent furniture from being taken apart once it has been manufactured and is in the customer’s home.

It may be intricate to put back together once removed and require a professional, or it may even compromise the safety of the furniture.

Simply replacing standard fixings with security fixings will prevent the amateur user from tampering with it.

It may also be useful to employ tamper proof screws in products where you would like to be the only option for maintenance and repair. This would mean that users would not be able to attempt to fix their product, hence preventing them damaging the product further through attempting to fix internal mechanisms should things go wrong.

It is common belief that a simple test for stainless steel is to check with a magnet. If it attracts, the product is not stainless steel. However, this assumption is incorrect.

“The stainless steel fasteners I received stick to a magnet.” This is one of the more frequently heard complaints among users. Stainless steel fasteners being nonmagnetic is also one of the largest misconceptions.

This post attempts to explain why most stainless steel fasteners are at least slightly magnetic and why many are so magnetic they are attracted to even weak household magnets.
