BAERCOIL Thread Repair and Thread Reinforcement

Thread Reinforcement

Low strength material such as aluminium, fibre-reinforced plastics (FRP), iron castings and magnesium alloys have poor threading properties and the threads created in these materials tend to wear out quickly. This problem can be rectified by thread reinforcement which is typically performed using threaded inserts. Threaded inserts not only provide a strong thread in materials with difficult machining characteristics, but they also reduce the amount of material required by being able to use screws and bolts of smaller diameters and shorter lengths. This is made possible by the high thread resilience of BaerCoil thread inserts which save material usage by up to 10-30%. This results in a reduction of weight and space which is often crucial in aerospace and automobile industries. The saving of material also minimises the total cost of production.

 

Thread Repair

¿¿¿Threads within a hole often get worn out over time or damaged due to various reasons such as low strength material or improper fastener size, torque specifications or installation. These damaged threads can be fixed easily using thread inserts such as wire thread inserts and self tapping inserts. Baercoil thread inserts help salvage parts rejected due to damaged threads while maintaining the original thread size, thus reducing costs. Baercoil thread inserts also increase the strength of the thread and is corrosion resistant.¿¿¿

BAER

BAER is a leading manufacturer of thread inserts from Germany with over 35 years experience in the field of threading technology. With this far-reaching treasure trove of experience, they have established themselves as an expert in threading technology. They provide two types of high quality threaded inserts:

  • Wire thread inserts - BAERCOIL
  • ¿¿¿Self tapping solid inserts - BAERFIX

Product Price: Ask Latest Price

BAERCOIL Taps differ from standard taps dimensionally. They have a larger diameter but the same pitch as a standard tap.
in order to accommodate the wire thread insert. BaerCoil Screw Thread Inserts (STI) taps are manufactured to precise standards from High Speed Steel (HSS) or (HSSE) with ground threads.

The Wire Thread Insert when installed into a correctly tapped hole will provide the applicable internal thread tolerance for the installed bolt.

Types of taps available.

Bottoming tap
chamfer: Form D (3-4 piches)
for through hole and blind hole
Bottoming Taps can be used by hand or machine

Machine tap
chamfer: Form B (about 4 piches)
for through hole

Machine tap
chamfer: Form C (2-3 piches)
for blind hole

forming tap
chamfer: Form D (3-4 piches)
for through hole and blind hole
Advantages:
- increased pull out stength and torque of the
formed threads
- creates a better surface quality
- no removal of swarf, no jaming of swarf
- higher forming speed as compared to
thread cutting
- greater tool lifetimes
Material:
Mouldable materials such as aluminium,
copper and zinc alloys, steel up to 700 N/mm²,
stainless steels

Tap with pilot nose thread repairing
- For tapping holding threads in
damaged metric threads.
- no pre-drilling
- mainly for spark plug
- for through holes and deep
blind holes

Compatibility
Important: BaerCoil taps are compatible with wire thread inserts and taps f rom other manufacturers. They are of ten called “STI“ or “EG“ taps.

Product Price: Ask Latest Price

The latest innovation from BAERCOIL is the Thread Forming Tap. The thread is formed not cut and the parent thread material is compressed to make it stronger.
The result is that the thread into which the Baercoil insert is fixed has a significantly higher load capacity.
Process of thread forming is faster and produces no chips. Additionally the tap has a longer life.

in the free state they are greater in diameter than the tapped hole into which they are installed. In the assembly operation the torque applied to the tang reduces the diameter of the leading coil and permits it to enter the tapped thread. When the torque or rotation is stopped, the coils expand with a spring-like action anchoring the insert permanently in place against the tapped hole. No staking, locking, swaging, keying, nor interference fit is required to retain helical thread inserts, thereby eliminating stress concentration in the parent material. The helical insert automatically adjusts itself, radially and axially, to any expansion or contraction of the parent material.

Baercoil inserts are the finest inserts made in germany.

BrandBAERCOIL

In addition to “free-running” insert characteristics, BaerCoil® “screw grip” thread inserts have one or more polygon-formed windings, which have a clamping effect on the flanks of the inserted screw. We only recommend using screws with a higher screw property class (from 8.8 on) because of this screw locking or screw clamping effect. An elastic and flexible frictional connection is formed. The clamping torque is comparable to the indications in DIN 267 Part 15 and ISO 2320. BaerCoil® “screw grip” thread inserts are predominantly used in areas where screw connections must remain tight while exposed to impacts, constant vibrations and movements

Product Details:

BrandBAERFIX

BaerFix® Thread Inserts have a conical lead with cutting slots on the metric external thread. They are designed to cut their own threads as they are being driven into a drilled hole (= self-tapping). This provides a secure and high-strength anchor in the parent material. BaerFix® Thread Inserts create wear-free and vibration resistant bolted connections because of its close tolerances and the self-tapped thread. In some cases the Insert has a minimal inward springing action, which creates a screw locking effect. If this is not wished, you can use BaerFix® Thread Inserts with cutting holes. These are suitable for creating highly durable and wear resistant bolted connections in materials with low shear resistance.

ADVANTAGES.
Large effective shearing surface The BaerFix® Thread Insert has a larger effective surface, which ensures a higher degree of pull-out strength, i.e. an M 5 is often sufficient instead of a cut M 6 thread.
Flange cover In a work piece made of a light alloy, the BaerFix® Insert achieves almost maximum pull-out strength with only 30 % flange cover.
Pull-out strength A BaerFix® Thread Insert is highly durable. Using in light alloys for example, helps achieving a pull-out strength which far exceeds the yield strength of a screw 8.8.
Minimize weight & space Weight saving is unmatched - an important design feature for many products, particularly airborne equipment. Space saving is maximized, permitting the use of standard configurations with oversize requirements - as is necessary to accommodate solid bushings. A bigger radius equal to the nominal bolt size fit for higher load and forces.
Minimize total costs Overall production cost savings may be realised by using a less expensive material and still maintain the required thread strength with BaerFix® Inserts. Costs savings apply in many directions - lower insert costs, lower installation costs and smaller bolts do all result savings.
Thread Repair In addition to thread reinforcement the BaerFix® Inserts also are used for repairing broken threads. In this process rejected components can be reclaimed by installing a thread insert. The created thread will keep its original dimension and also gets reinforced by raising the pull-out strength and corrosion resistance. Costs of acquisition and processing can be saved by repairing threads with BaerFix® Thread Inserts.
Applications It’s especially suitable for following materials: • aluminum and aluminum alloy • brass, bronze, cast iron • magnesium alloy • thermosetting plastics and thermoplastics (no rubber-soft thermoplastics)
Examples for applications: • Automotive industry: engines, transmissions, radiators, autobody etc. • Electrical and laboratory techniques: medical equipment, capacitors, boxes etc. • Household appliance: vacuum cleaners, electric iron, washing machines, cameras, mobile phones etc. • Plant and equipment construction: pumps, construction machines, different components etc. • Military machines: aircrafts, weapons etc
