Phillips Low Profile Self Clinch Captive Panel Fasteners

Phillips Low Profile Self Clinch Captive Panel Fasteners provide a method of mounting hardware to thin sheet metal. Their captive nature prevents damage typically caused by loose components while retaining access to an assembly.

The knurled self-clinching feature permanently fuses to the mating panel to prevent movement and rotation. This is achieved when squeezing force is applied using a press, which pushes displaced material around the knurls and into the undercut.

This mounting style does not require any hole preparation unlike other types, thus eliminating secondary operations for increased productivity.

These components can be supplied with a knurled head for extra grip or a smooth head to prevent manual access. The Phillips drive enables installation using a standard Phillips screwdriver or insert bit.

Phillips Low Profile Self Clinch Captive Panel Fasteners are intended for use in sheet hardness HRB 60 or less on the Rockwell B scale, or HB 107 or less on the Brinell scale.

The retainer and knob are made from Carbon Steel with a Nickel plated finish, the screw is made from Hardened Carbon Steel with a Nickel plated finish, and the spring is made from 300 Series Stainless Steel.

The screw, retainer and knob are also available with a Black nitride finish on request.

Available at Fastenright in thread sizes M3 to M6, with several shank lengths to accommodate a range of sheet thicknesses. #4 to 1/4″ Unified threads can also be supplied.
