• Full threading along the 25mm length maximizes engagement and load distribution

Professional Applications & Engineering Value

Engineered for demanding industrial applications where vibration resistance and long-term reliability are critical, these M10 hex head screws with nylon patch thread locker solve common fastening failures in machinery, automotive assemblies, and structural frameworks. The Class 8.8 zinc-plated steel construction delivers 110,000 psi tensile strength and Rockwell C22 hardness, ensuring structural integrity under dynamic loads. The external hex drive provides superior torque transmission during installation, while the coarse metric threading (1.5mm pitch) enables quick assembly without compromising holding power. These fully threaded screws maintain consistent clamping force across the entire 25mm length, making them ideal for applications requiring uniform stress distribution and vibration dampening in temperature-fluctuating environments.

Specification Summary & Compliance

Manufactured to ISO 4017 (DIN 933) standards with Class 6h thread fit precision, these metric screws ensure dimensional accuracy and reliable performance. The zinc-plated steel construction meets Class 8.8 strength requirements with verified 110,000 psi tensile strength and Rockwell C22 hardness. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and regulatory acceptance for international industrial applications.
