Key Features & Benefits at a Glance
- Exceptional tensile strength of 140,000 psi ensures reliable performance in high-stress industrial applications, minimizing fastener failure risks.
- Superior corrosion resistance from the black-oxide coating on alloy steel, extending service life in harsh or humid environments.
- High hardness rating (Rockwell C32) provides excellent wear resistance, maintaining thread integrity through repeated assembly cycles.
- Fully threaded design allows for maximum grip length and uniform load distribution across the entire fastener.
- Precision hex drive (8mm) enables secure tool engagement and efficient installation with standard metric tools.
- Class 10.9 strength grade guarantees consistent mechanical properties for critical bolting applications.
- Compliance with ISO 7380 ensures dimensional accuracy and interchangeability with global metric fastener systems.
Professional Applications & Engineering Value
Engineered for demanding industrial assembly and heavy machinery applications, these M12 hex button head screws combine Class 10.9 alloy steel construction with a black-oxide surface treatment to address common challenges like vibration loosening and environmental degradation. The coarse thread (1.75mm pitch) facilitates quicker installation in soft materials or when alignment adjustments are frequent, while the rounded button head profile provides a low-profile, snag-resistant finish ideal for tight spaces. With fully threaded design and right-hand thread direction, they deliver uniform clamping force in automotive frames, construction equipment, and manufacturing jigs where 140,000 psi tensile strength is critical for structural integrity.
Specification Summary & Compliance
This metric screw features M12 x 1.75mm coarse threads with Class 6g tolerance for precise fit, and an 80mm length under ISO 7380 manufacturing standards. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in regulated industries.
