 This non-magnetic stainless steel fasteners is ideal for use in assemblies requiring a moisture seal and in corrosive atmospheres. It presents an inherent seal against entrance of dirt, oils and moisture, which cannot be supplied by nut and screw type hardware without elaborate seals and time-consuming assembly procedure. The fastener also provides the usual mounting capability for tight or normally inaccessible places. Extension E provides additional thread length for thin panels. Our Extension Stainless Steel precision blind press nuts will provide strong threads of class 2B MIL-S-7742 for use in aluminum, mild steel and other materials of Rockwell Hardness 70 or less. The Extension Hardened Carbon Steel is preferred for use in noncorrosive atmospheres and will mount in harder materials than will extension stainless steel type fasteners, typically materials of Rockwell Hardness 80 or less. Typical push-out and torque-out maximums for a 66356-040-12 nut in standard chassis aluminum are 170 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. (*) The Cadmium Plate Finish (7) for Carbon Steel and the Passivate Finish (12) for Stainless Steel is recommended. |
