Professional Applications & Engineering Value

This M14 hex head screw delivers exceptional engineering value through its Class 8.8 steel construction and zinc plated finish, specifically designed to combat common industrial challenges. The fine 1.5mm pitch threading with Class 6h fit provides superior vibration resistance in machinery, automotive assemblies, and structural frameworks where loosening under dynamic loads is a critical concern. The fully threaded design ensures maximum engagement in tapped holes or with nuts, distributing clamp load evenly across the entire 50mm length. This metric screw solves alignment and galling issues common in high-cycle applications while maintaining Rockwell C21 hardness to prevent thread deformation during repeated installations. Ideal for heavy equipment, manufacturing fixtures, and construction applications requiring reliable, high-strength fastening solutions.

Specification Summary & Compliance

This fastener maintains precise Class 6h thread fit tolerance per metric standards with M14 x 1.5mm fine threading and right-hand thread direction. Manufacturing complies with ISO 8676 specification (equivalent to DIN 961) for dimensional accuracy and performance consistency. The product meets RoHS 3 (2015/863/EU) compliance for restricted substance control and REACH (EC 1907/2006) compliance for chemical safety, ensuring suitability for global industrial markets and environmentally conscious manufacturing operations.
