Self-Clinching Fasteners

CFE self-clinching fasteners are designed to provide strong threads in a minimum of space. They are available with locking and non-locking threads and are directly interchangeable with industry standards.

300 Series Stainless Steel.

Retaining Rings

Metric DIN 471 external and DIN 472 internal retaining rings (circlips) are thin, circular, metal stampings used to prevent movement between mating components, reducing vibration and maintaining proper position while permitting easy disassembly.

Exotic Alloy & High-Temperature Fasteners

A range of exotic alloy and high-temperature fasteners for demanding industries, with technical guidance on hydrogen embrittlement across aerospace, automotive, marine, oil and gas, medical, and pressure vessel applications.

Of the stainless steels, A286 is the best fastener material for aerospace usage.; - Monel® (e.g., K-500): This nickel-copper alloy is renowned for its exceptional resistance to seawater corrosion, particularly in high-velocity conditions, making it ideal for shafts, valves, and fasteners exposed to flowing seawater.

Threaded Inserts

Mechanical fastening components installed into a prepared hole to provide strong, reusable internal threads in soft, thin, or frequently serviced base materials. Self-tapping variants cut or form their own thread in the receiving hole, reducing or eliminating the need to pre-tap.

For 3D printed parts and plastic housings, brass heat-set inserts are one of the most common choices.; Threaded inserts are commonly made from stainless steel, carbon steel, brass, and other engineering materials.
