The captive fastener broaching standoffs have different surface treatments. They help fight rust, make soldering simpler, let electricity flow better, and even make them look nicer.

Common ones are electrolytic nickel coating, tin coating (either pure or an alloy), zinc-nickel alloy coating (which is better at fighting rust), and silver coating (good for letting electricity flow).

Which treatment you pick depends on what the environment needs, the soldering process, and what’s required for electrical performance.

During installation, the broaching standoff is affixed using a riveting process to ensure strong, vibration-resistant bonding.

Customized specifications and sizes

The captive fastener broaching standoff come in lots of standard sizes, and you can get custom ones too.

Main specs include the stud’s diameter (both the shank and the head), total height, thread size and length (if the end of the stud has threads), and the size of the hole needed in the PCB.

Getting the dimensions right is important. It makes sure the stud fits properly in the PCB, gets the right clamp force when you rivet it, and works with the other parts it connects to.

What is the typical weight/load capacity?

How much weight these captive fastener broaching standoff can handle depends a lot on their size,like diameter and length,what material they’re made of (steel or aluminum), how thick the PCB is, and the size of the hole.

Like, a typical 3mm stainless steel stud in a 1.6mm PCB can usually handle 300-500 N (that’s 30-50 kg) of pull-out force.

We have technical sheets that list the shear and pull-out strength. Always check these specs to make sure the stud you pick can handle the mechanical needs of what you’re using it for.
