Broaching-Type Fasteners
Series CKF2 & CKFS2
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.

Thread: Class 2B, MIL-S-7742; (6H ISO Metric).
Use in: Materials with Rockwell Hardness of B-60 or less.
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.

Note: CKF2 & CKFS2 broaching fasteners 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.
