All Captive Broaching Fasteners for PCBs, install into a round hole, which may be drilled in non-ductile materials. Captive Broaching Fasteners are pressed into printed circuit boards and non-ductile materials and held permanently in place by an interference fit.
Common types of Self Broaching Fasteners:
Nuts, Studs, Stand-offs

 
 
CKF2 and CKFS2 Broaching-Type Fasteners are designed for use on printed circuit boards and on most brittle or hard materials: glass laminates, epoxy or resin with paper, nylon, or canvas bases. They are also used on materials too thin or unsuitable for threading, such as acrylic and polycarbonate panels.

Since the aforementioned materials do not flow under pressure, these fasteners are designed with a knurled shank that can be pressed into a drilled hole. The shank grips the board with an interference fit by broaching its way into the panel as it is squeezed into the holes. All fasteners from Captive Fastener are identical to industry standards so that they can be fed through standard automatic insertion equipment.

 
 
 
CKFE and CKFSE threaded and non-threaded standoffs allow screws to be inserted through ultiple layered boards for stacked assemblies. All fasteners from Captive Fastener are identical to Industry standards so that they can be fed through standard automatic insertion equipment.

Note: CKFE & CKFSE broaching

Standoffs are designed for unplated through-holes. When installed in plated through-holes, a hole tolerance of +.005 - .001 in. (+.13 - .03 mm) should be used. When used in plated through-holes performance will be reduced and plating may be damaged by knurl. † Not stocked, available on special order.
 
 
 
CKFH Broaching-Type Studs are electroplated with tin so they are readily solderable. Thus, they can be used both as solderable connectors and as permanently mounted mechanical fasteners.
