Superior fastening performance is provided by the miniature press nut through strong, permanent, wear resistant threads for soft brass, aluminum, mild steel, or thermoplastic panels, part or chassis. Thread depth and load retention is made constant regardless of sheet material or thickness. Extension E provides additional threads for thin brittle materials.
Threads provided, are class 2B, MIL-S-7742 for materials of Rockwell hardness 70 or less (stainless steel nuts) and 85 or less (carbon steel nuts) for hole sizes .108 up to .150.
Typical retention forces are 150 lbs push-out, and 25 inch lbs. torque-out in standard chassis aluminum.
Captive hardware facilitates easy one-side installing for assemblies in normally hard-to-reach places.
Steel Inserts: for use in low carbon steels that are 1/2 hard or softer and for stainless steel in the annealed condition.
Stainless steel inserts: for use in most aluminums or in low carbon steels that are 1/4 hard or softer.
The Cadmium Plate Finish (7) for Carbon Steel and the Passivate Finish (12) for Stainless Steel is recommended.
