S-90180A627 M8 x 70 mm ISO 4014, DIN 931 High-Strength Metric Class 10.9 Steel Hex Head Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength with 150,000 psi rating and Class 10.9 grade for reliable performance in high-stress industrial environments
• Superior corrosion resistance through blue-dyed zinc plating that provides both aesthetic identification and lasting protection
• Optimized thread engagement with M8 coarse thread (1.25 mm pitch) ensuring quick installation and secure fastening in various materials
• Precise dimensional control meeting ISO 4014/DIN 931 specifications for consistent fit and interchangeability
• Enhanced durability from Rockwell C32 hardness that maintains thread integrity through repeated use
• Secure external hex drive allowing high torque application with standard tools while preventing stripping
• Environmental compliance with RoHS 3 and REACH standards for safe use across regulated industries

Professional Applications & Engineering Value

These M8 hex head screws deliver critical engineering solutions where high tensile strength and corrosion resistance are paramount. The Class 10.9 steel construction with Rockwell C32 hardness ensures reliable performance in structural applications, machinery assembly, and heavy equipment where vibration and dynamic loads challenge fastener integrity. The blue-dyed zinc plating provides both corrosion protection and visual identification while the metric coarse threading (1.25 mm pitch) enables rapid installation in steel frameworks, construction projects, and industrial manufacturing. The partially threaded design concentrates engagement where needed most, making these ISO 4014 compliant fasteners ideal for applications requiring precise clamp load distribution without compromising joint security.

Specification Summary & Compliance

Manufactured to ISO 4014 specifications (equivalent to DIN 931) with Class 6g thread fit tolerance ensuring precise engagement. These metric hex head screws feature M8 x 1.25 mm coarse thread spacing with 22 mm minimum thread length and 70 mm overall length. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for use across international markets. The Class 10.9 strength rating corresponds to 150,000 psi tensile strength with Rockwell C32 hardness verification.
