Professional Applications & Engineering Value

This M12 hex head screw delivers exceptional engineering value through its Class 8.8 steel construction and zinc plated finish, specifically designed to address industrial fastening challenges. The coarse thread pitch (1.75mm) enables rapid installation in construction, machinery assembly, and structural applications where time efficiency is critical. The partially threaded design provides an unthreaded shank section that maintains superior clamping force and resists shear stresses, making it ideal for bolted connections requiring precise joint integrity. With Rockwell C21 hardness and 110,000 psi tensile strength, this metric hex bolt withstands vibration, dynamic loads, and harsh environmental conditions while the corrosion-resistant zinc plating extends service life in outdoor or chemically exposed environments.

Specification Summary & Compliance
