Datasheet
Datasheet Summary
Powered by GS/AI

F4-256-1 is a PEMSERT® self-clinching flush nut designed for installation into stainless steel sheets as thin as 0.060"/1.5 mm, providing load-bearing threads without protrusions on either surface. It features an M2 x 0.4 thread, a shank diameter of 4.37 mm, and requires a 4.35 mm nominal hole. The fastener installs flush and is suitable for use before sheet forming. Axial tensile strength is 130 lbs (570 N), with a recommended tightening torque of 1.50 in-lbs (0.16 N•m). It achieves a minimum pushout resistance of 7200 lbs (32 kN) in 300 series stainless steel and 2000 lbs (8.9 kN) in 5052-H34 aluminum. The hexagonal head ensures high axial and torsional strength during installation.
