Hex Head Close Tolerance Shear Bolt (Drilled Shank)

Technical Description

Precision heavy-duty aerospace tension and shear hex head bolt conforming to manufacturer part number NAS6203-10D, featuring a factory drilled shank to accommodate cotter pins or safety wire safety configurations. Fabricated from premium, heat-treated high-strength alloy steel (comp 4340, E4340, or 8740 variants) with a protective cadmium plating and chromate finish (Type II, Class 2 under QQ-P-416) for superior structural resilience and fluid corrosion resistance. Engineered specifically for rigid close-tolerance performance requirements under substantial vibrational stresses, maintaining a minimum tensile strength of 160,000 PSI and a shear capacity of 95,000 PSI. Optimized for high-performance structural attachments and critical airframe sub-assemblies across commercial and general aviation aircraft configurations.
