Bolt, 100° Flat Countersunk Head NAS333CPA11

Technical Description

High-strength precision alloy steel structural aerospace bolt manufactured to NAS333 technical parameters. Thread dimensions detail a right-hand #10-32 UNJF-3A tight-tolerance fit class featuring a nominal grip section of 0.6875 inches (11/16") designed to handle structural shear forces. Constructed from premium vacuum-melted high-tensile alloy steel providing a minimum ultimate tensile strength rating of 160,000 PSI to maintain critical assembly clamping preloads. Outfitted with an aerodynamically flush 100-degree flat countersunk tension head configuration utilizing a cross-recess cruciform drive layout. Finished with an all-over cadmium plating surface treatment to deliver reliable galvanic isolation and exceptional corrosion resistance across safety-critical airframe structural joints.
