Set Screws are blind (headless) fasteners with an internal hex drive. It is this drive style that classifies stainless steel screws in this selection as set screws, which are driven by a hex bit or Allen wrench. Grub Screws are used in a tapped hole and tightened to hold an exterior object in place within or against another object, via friction between the point or end of the screw and the material that is being fastened.

Set Screws are also often used in applications where a flush installation and the look of the final assembly are important, such as furniture assembly. Socket Set Screws will run flush with the installation surface. They are often plugged after installation for a hidden fastener look. These qualities are what make set screws commonly used in applications where a flat surface is important, such as handles, grips, surfboard fins, and furniture or machine assembly. Because a flush surface is important on complex machines, Set Screws are also commonly used in gears, pulleys, and wheel in machines with moving parts.

A stainless steel set screw is a type of screw generally used to secure an object within or against another object. The most common examples are securing a pulley or gear to a shaft. A blind set screw (known in the UK as a grub screw, quite possibly from its figurative resemblance to a soil-dwelling grub) is almost always driven with an internal-wrenching drive, such as a hex socket (Allen) socket. The set screw passes through a threaded hole in the outer object and is tightened against the inner object to prevent it from moving relative to the outer object. It exerts compression or clamping force through the bottom tip that projects through the hole.

Available with points including Cup Point, Cone Point, Flat Point and Dog Point.

 

One might often need to use a flat point when the screw must press perfectly flat against a surface.

Dog Point

They are used for permanent location of one part to another. They have flat end with the threads stopping short of the end.

The tip is normally located into a groove in a shaft and allows the shaft to rotate whilst retaining the part in place.

The end is spotted in hole drilled in shaft or against flat (milled). They often replace dowel pins. Works well against hardened members or hollow tubing.

Available in ISO 4028 or DIN 915

The Socket Button Head Screw design as per ISO 7380-1 is primarily used where a lower profile head is required and for aesthetical reasons.

Button head socket cap screws combine the similar shape of a pan head with the driver of a socket head. The socket driver is ideal for low clearance applications that require a large area clamping face.

Compared to a standard socket head cap screw, button heads have a lower and wider profile which can be useful when the clamping material is too thin to counter-bore. A button head socket cap screw's large diameter face also helps to distribute force more evenly.

The Torx compatible drive is a reliable method of fixing screws. This drive can take more torque and does not slip.

The hexalobular socket screw drive, known as Torx or 6-Lobe or star drive, uses a star-shaped recess in the fastener with six rounded points.

The reliable thread forming screw for easy fastening into thermoplastics.

Plastic is proving to be a versatile material for the future in spite of the hue and cry against it. It is opening up a world of innovations where smaller, lighter and cheaper is driving the markets.

But it comes with its own technological challenges such as suitable fastening solutions.

The regular screws are completely unsuitable leading to development of specialised screws for use in plastics. With the increasing use of 3D printing technology, it has become imperative that a reliable screw capable of providing a secure strong joint in plastics is available.

With the increasing use of 3D printing technology, it has become imperative that a reliable screw capable of providing a secure strong joint in plastics is available.

An effective solution is to use thread-forming screws with 30° thread form.

 

This feature allows the screw to make deeper grooves into the material and capture more of it between the threads, creating an even greater resistance to shear force while reducing stress.

Our screws are made from Stainless Steel AISI-304 Grade to provide a strong corrosion resistant assembly for a long life to your product.

Slim head screws are 77% thinner than conventional pan head which gives a flat external surface and contributes to low-profile design and weight saving. 

It comes with a 6-Lobe drive that provides for a slipless installation with reduced operator effort and fatigue.

 

The large diameter heads of the low-profile screws have been engineered to spread the load across a wide surface to provide greater holding power in thinner material applications. These offer a sleek, unobtrusive and polished finish for any design.
