PR10 self-clinching flush-mounted retainers are designed for secure thread retention in thin sheet materials, accommodating #6-32 (0.138-32) internal threads per ASME B1.1, 2B. The part installs in sheet thicknesses of 0.050 in minimum for self-clinching and 0.125 in for flush mounting, with a required hole size of 0.312 in ±0.003 in. It requires a minimum distance of 0.33 in from the hole centerline to the edge. The retainer has a shank diameter of 0.125 in max, a body height of 0.075 in nominal, and is made from 300 series stainless steel with a passivated finish tested per ASTM A380. It is rated for use in sheet materials with a hardness of HRB 70 or less or HB 125 or less.
