Captive Fastener Broaching Standoffs

Captive fastener broaching standoffs are made of different materials, with varying application scenarios and characteristics. Mild steel (such as 1008 or 1010) offers low cost and high strength; stainless steel (such as 303 or 304) is rust- and corrosion-resistant and suitable for use in humid environments; and aluminum alloy (such as 6061) is conductive and lightweight. Choosing the right material requires a comprehensive consideration of strength, weight, conductivity, corrosion resistance, and cost-effectiveness, tailored to the application scenario, location, and requirements.

Install

The captive fastener broaching standoffs install pretty efficiently.

Using special pneumatic, hydraulic, or servo-electric riveting machines, putting them in is quick and consistent. You only need access from the stud side of the PCB.

This one-sided process makes assembly line design and automation simpler.

Dealing with these studs before installation is easy,they’re usually supplied in bulk or on reels, which works with automated feeding systems.

Under high temperature or thermal cycle environment

The captive fastener broaching standoffs are made to stay stable in tough environments.

The stainless steel ones do well here,they can usually handle temperatures from -50°C up to over 200°C.

The mechanical riveting makes a tight connection that doesn’t loosen as much during heating and cooling cycles, compared to things like glues or soldered parts.

Just make sure the material of the stud matches the temperatures your assembly will see and how much it heats up and cools down. That way, it’ll stay reliable for a long time.
