- Consistent dimensional accuracy with Class 6h thread fit guarantees perfect mating with standard metric nuts
- Comprehensive regulatory compliance including RoHS 3 and REACH for global manufacturing acceptance
Professional Applications & Engineering Value
These M5 hex head screws deliver critical performance advantages for industrial assembly applications where vibration resistance and structural integrity are paramount. The Class 8.8 steel construction provides optimal strength-to-weight ratio, while the coarse metric threading prevents loosening under dynamic loads. The zinc plating offers essential corrosion protection for equipment exposed to moisture or chemical environments. Engineered to ISO 4017/DIN 933 standards, these fully threaded fasteners ensure dimensional consistency across production runs, reducing assembly time and improving joint reliability in machinery, structural frameworks, and heavy equipment manufacturing.
Specification Summary & Compliance
Manufactured to precise Class 6h thread fit tolerances with M5 x 0.8mm coarse threading and right-hand thread direction. Complies with international standards including ISO 4017, DIN 933, and ISO 898 for mechanical properties. Meets environmental regulations: RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant. The Rockwell C21 hardness and 110,000 psi tensile strength ensure consistent performance under demanding conditions.
