Professional Applications & Engineering Value

This 3/4"-10 UNC Square Head Screw delivers critical engineering solutions where medium strength fasteners are required. Manufactured from SAE Grade 5 steel with Rockwell C25 hardness, it provides the optimal balance between tensile strength and machinability. The zinc yellow-chromate plating creates a protective barrier against oxidation and chemical exposure, significantly extending service life in manufacturing equipment, structural frameworks, and machinery assembly. The external square drive design prevents cam-out during high-torque installation, while the coarse UNC threads ensure rapid installation in steel frameworks, heavy equipment, and construction applications where vibration resistance and reliable clamping force are paramount.

Specification Summary & Compliance

This square head fastener features Unified Standard Class 2A thread tolerances with 3/4"-10 UNC coarse threading and 3-inch length. Manufactured to ASME B18.2.1 specifications, it guarantees dimensional precision and interchangeability. The SAE Grade 5 classification confirms consistent mechanical properties including 120,000 psi tensile strength and Rockwell C25 hardness. The zinc yellow-chromate plating provides corrosion protection while maintaining compliance with industrial standards for heavy-duty fastening applications in the inch measurement system.
