Bolt, Shear, Flush Reduced Head NAS1581C3T6P

Technical Description

High-strength precision corrosion-resistant steel structural shear bolt manufactured to NAS1581 specification metrics. Thread size configuration tracks a precision right-hand 10-32 UNJF-3A close-tolerance fit class featuring a nominal grip length of 0.375 inches and a total fastener length of 0.738 inches. Fabricated from high-tensile corrosion-resistant steel providing a minimum ultimate tensile strength rating of 160,000 PSI. Outfitted with an aerodynamically flush 100-degree reduced flat countersunk head utilizing a high-torque internal offset cruciform recess drive mechanism to completely suppress drive cam-out under tight industrial preloads. Finished with a comprehensive passivation surface treatment to eliminate external contaminants and secure long-term galvanic wear resistance within safety-critical airframe subassemblies.
