Professional Applications & Engineering Value

This 3/4"-10 UNC Square Head Screw delivers critical engineering solutions for industrial assembly challenges where medium strength fasteners with reliable corrosion protection are essential. The SAE Grade 5 steel construction provides optimal balance between strength and ductility, preventing brittle failure under dynamic loads. The zinc yellow-chromate plating creates a protective barrier against oxidation and chemical exposure, making these square head screws ideal for outdoor equipment, machinery frames, and structural applications. The coarse UNC threading ensures rapid installation in steel-to-steel connections while the external square drive allows for high-torque application without cam-out issues, significantly reducing assembly time in production environments.

Specification Summary & Compliance

Manufactured to exact Unified Standard Class 3A thread tolerances with 3/4"-10 UNC coarse threading and right-hand thread direction. Complies with ASME B18.2.1 dimensional specifications and SAE J429 material standards for Grade 5 fasteners. Features full threading along the 2" length with external square drive (1 1/2" head height, 1 1/8" head width). The zinc yellow-chromate finish provides corrosion protection while maintaining compliance with industrial fastener requirements.
