S-96144A212 M8 x 12 mm DIN 912, ISO 21269 Alloy Steel Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength of 170,000 PSI ensures reliable performance under high-stress conditions, reducing the risk of fastener failure in critical assemblies.
• Superior corrosion resistance from the black-oxide coating extends service life in harsh industrial environments, minimizing maintenance and replacement costs.
• Precise Class 5g6g thread fit guarantees smooth installation and secure fastening, preventing cross-threading and improving assembly efficiency.
• High hardness rating (Rockwell C37) provides excellent wear resistance, maintaining thread integrity and drive engagement through repeated use.
• Compact 6mm hex drive design allows for easy access in confined spaces while delivering maximum torque transfer without stripping.
• Full compliance with DIN 912/ISO 21269 standards ensures dimensional accuracy and interchangeability with existing metric fastener systems.
• RoHS 3 and REACH compliance meets international environmental regulations, making these screws suitable for global supply chains and sensitive applications.

Professional Applications & Engineering Value

These Class 12.9 alloy steel socket head cap screws are engineered to address common industrial challenges where vibration resistance, high clamping force, and space constraints are critical. The fine M8 x 1mm thread provides superior holding power in materials prone to stripping, while the black-oxide surface treatment offers reliable protection against corrosion in manufacturing, automotive, and heavy machinery applications. The fully threaded design ensures consistent engagement depth, making them ideal for precision assemblies requiring uniform stress distribution. With their high-strength characteristics and standardized DIN 912/ISO 21269 dimensions, these fasteners deliver predictable performance in jigs, fixtures, and structural components where failure is not an option.

Specification Summary & Compliance

This socket head cap screw features precise Class 5g6g thread fit tolerance per ISO metric standards, ensuring compatibility with corresponding nuts and tapped holes. Manufacturing specifications strictly adhere to DIN 912/ISO 21269 dimensional requirements for head profile, drive size, and thread geometry. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, containing no restricted substances above threshold limits. All mechanical properties including 170,000 PSI tensile strength and Rockwell C37 hardness meet or exceed Class 12.9 performance criteria for demanding industrial applications.
