Application specific fastener designs that provide the ability to cold form “near net” shaped parts. The benefits of Cold Formed Specials include material savings, reduced scrap, increased production rates, potential part consolidation and a reduction in overall fastening costs.

Utilized extensively in the automotive safety restraint and seating market segments, Anchors and Formed parts generally consist of a multi station cold headed blank combined with operations including stamping, flattening, coining, bending and piercing. These parts end up in critical applications including seat belt pre-tensioners, locking pins, seat belt anchor devices and seat track couplers to solve demanding design issues and reduce cost.

Specifically engineered thread-forming fasteners for metal, thermal and thermal set  plastic applications. These products are designed to deliver low thread forming and high strip out torque, improved clamp load, superior vibration resistance, increased joint stability and the reduction or elimination of threaded inserts or the associated tapping costs.

From simple to complex, ATF provides expertise in combining cold formed components with components of other manufacturing technologies including metal stamping, plastic molding, powdered metal and rubber products to provide lower cost assembled components and assemblies.

HELICOIL^® plus thread inserts create high-strength, wear-resistant, heat-resistant threads of highest precision. They are available in free running and screwlock version. The green or red colour allows easier identification when they are installed.

For internal and external threads of components with small wall thicknesses, Böllhoff offers RIVKLE^® blind rivet nuts and studs. These elements are mounted without counter pressure ("blindly") and can therefore also be set at hollow sections.
RIVKLE^® blind rivet nuts and studs are available in many variations and sizes and therefore offer numerous fastening solutions with additional functions.

Not only in the automotive industry do production processes based on modular construction succeed.Here, individual components are supplied to the assembler where they only have to be assembled.To ensure flawless series production certain tolerances are assumed. The automatic tolerance compensation system FLEXITOL^® provides a technically and economically optimised solution.

RIVSET^® self-pierce riveting is a process for a high strength mechanical joining of similar or combinations of materials. Also several layers can be joined without problem.

The product range of RIVSET^® self-pierce rivet systems include manual systems as well as systems for automated manufacturing, which are designed for different application ranges and adapt to varied manufacturing environments.

Steel- and stainless steel materials and also aluminum and other nonferrous metals can be joined econonical and enviromentally friendly.

The product range of RIVCLINCH^® systems are designed for different application ranges and adapt to varied manufacturing environments.

The new RIVTAC^® automation system enables fully automatic joining. It is designed for high volume applications and provides maximum flexibility in production planning.

The RIVTAC^® technology is particularly suitable for joints of aluminium, steel, plastics, non-ferrous metals as well as for mixed joints, multiple-layer joints and hybrid joints of these materials.

EJOT ALtracs® Plus screws are thread-forming fasteners developed for maximum strength values in light alloy assemblies and other non-ferrous metals such as zinc, copper or brass. The ALtracs® Plus is designed for direct assembly into cast holes.

With the FDS® screw EJOT developed an alternative for the common practice of pre-drilling of the components to be joined. Through an optimisation of the fastener layout the joining of a body-in-white in space frame structure can be carried-out completely without pre-drilling. For this the fastening parameters where adjusted and the geometry of the FDS® screw below the screw head was optimised, since a small amount of the material flows against the fastening direction.

EJOT Spiralform® screws are special fasteners for reliable and trouble-free metal joints, especially in steel and and stainless steel. Thread-forming and fastening are only one step with this screw. An accurate, tight fitting thread with high strength properties is always formed. This guarantees optimal resistance against loosening under dynamic stress.

EJOT EJOFORM® products are innovative and customer specific fastening and design engineering solutions. They meet various requirements, such as bracket, stop bolt, spacer or adjustment element. The individual products are manufactured in a multiple step cold-forming process. With this technology a wire section is formed into a complex fastening element in up to six blows. 

EJOWELD® offers the possibility to join different materials (lightweight material / high strength steel) without any pre-treatment (cleaning, de-coating, pre-drilling).

Ball studs are ideal for linkage assemblies that can be detached regularly or secured permanently, as they can be used for a wide range of applications.

This product has been developed to provide a high value fastening solution for those customers that are transitioning more and more from steel to aluminum body and frame components that are used for grounding applications.

Typical fastener designs are acorn nuts, wing nuts, wing bolts and tie down fasteners.  For certain applications, insert molded fasteners can provide cost, weight, aesthetic and design benefits over all-metal fasteners.

Thermal cycles…High Vibration…these wreak havoc on bolted joints causing bolts to loosen and clamp loads to be lost.  For those high temperature and high vibration applications like engine exhausts and turbo chargers, the top OEMs turn to our High Temperature Bolts and Studs.
