Professional Applications & Engineering Value
This M14 hex head screw delivers exceptional engineering value through its Class 8.8 steel construction and zinc plating finish, specifically engineered to address common industrial fastening challenges. The partially threaded design with fine thread spacing (1.5mm pitch) provides optimal stress distribution while preventing loosening under vibration, making it ideal for machinery, structural steel connections, and heavy equipment assembly. The external hex drive accommodates high installation torque requirements without stripping, while the Rockwell C21 hardness ensures durability against wear and deformation. These metric screws solve critical issues of joint integrity and corrosion protection in manufacturing, construction, and automotive applications where reliable heavy-duty fastening is paramount for operational safety and longevity.
Specification Summary & Compliance
This fastener maintains precise Class 6h thread fit tolerance and dimensional accuracy per ISO 8765 specifications. The metric thread system features M14 x 1.5mm fine pitch with right-hand threading and 34mm minimum thread length. Manufacturing compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring responsible production practices and material safety.
