Spline-press extension nuts are made or case-hardened carbon steel and non-magnetic stainless steel and are designed for use in thin metal panels and brittle plastic parts where tapped holes are not satisfactory.
The torque resisting splines literally cut their way down into the mounting material, biting in for torque resistance and providing a holding collar against pull-out forces.
The specially engineered spline bevels minimize destructive compression forces normally encountered on entry and which can fracture non-ductile substrate materials. The extension enables the user to space brackets and other associated hardware away from the chassis housing.
Typical push-out, and torque-out values in glass epoxy laminate are 100 lbs., and 20 inch lbs. respectively. 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.
INSTALLATION NOTE: Minimum panel thickness .093 Counterbore Flat Bottom hole to depth .080 _.005/-.000.
