- Superior corrosion resistance thanks to black steel construction and compliance with RoHS 3/REACH environmental standards
- Optimized torque transmission through external hex drive design and 17mm head width for secure installation
- Precision thread engagement with Class 6g fit and M10x1.5 coarse thread profile ensuring vibration resistance
- Enhanced durability from Rockwell C21 hardness and Class 8.8 strength grade for long service life
- Versatile partial threading allowing both clamping and unthreaded shank functionality in 130mm length
- Global compatibility meeting ISO 4014 specifications (equivalent to DIN 931) for international projects
Professional Applications & Engineering Value
These M10 hex head screws deliver critical engineering solutions where high tensile strength and vibration resistance are paramount. The Class 8.8 steel construction combined with coarse thread pitch provides superior clamping force in structural steelwork, machinery assembly, and heavy equipment manufacturing. The partially threaded design allows the unthreaded shank to bear shear loads while the threaded portion maintains tension - ideal for bolted connections requiring precise preload. With ISO 4014 compliance and Class 6g thread fit, these metric hex bolts ensure consistent performance in automotive, construction, and industrial maintenance applications where reliability cannot be compromised.
Specification Summary & Compliance
Manufactured to ISO 4014 standards (equivalent to DIN 931) with Class 6g thread tolerance for precision fit. The M10x1.5 coarse thread configuration provides optimal engagement in various materials. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Features 32mm minimum thread length on 130mm overall length with right-hand thread direction. Mechanical properties include Class 8.8 strength grade, Rockwell C21 hardness, and 110,000 psi tensile strength.
