Product Description

Cylindrical head hex socket screws M14x40, also known as M14x40 hex socket cap screws, are precision fasteners designed for high-strength applications requiring flush mounting and space-optimized assembly. With a nominal diameter of 14mm and 40mm shank length, these hex socket head screws M14x40 typically feature ISO 4762/DIN 912 compliance, offering tensile strengths up to 1200 MPa in grade 12.9 steel variants. The internal hex drive (6mm Allen key size) enables secure torque transmission up to 170 N·m. Common surface treatments include zinc plating for corrosion resistance in automotive and machinery industries. Their low-profile cylindrical head suits confined spaces but requires precise counterboring. Installation advantages include uniform stress distribution and vibration resistance, though proper driver engagement is critical to prevent socket rounding.
