S-91290A128 M10 x 85 mm DIN 912 Alloy Steel Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional strength and reliability with Class 12.9 rating and 170,000 PSI tensile strength, ensuring secure fastening in high-stress industrial environments.
• Superior corrosion resistance thanks to the black-oxide coating on alloy steel, extending service life in demanding conditions.
• Precise and secure installation enabled by the 8 mm hex socket drive, allowing high torque application without slippage.
• Optimized thread engagement with M10 coarse thread (1.5 mm pitch) and Class 5g6g fit, providing quick assembly and vibration resistance.
• Versatile partial threading (32 mm thread length on 85 mm screw) offers flexibility for applications requiring both threaded and unthreaded sections.
• Consistent dimensional accuracy per DIN 912 standard, ensuring interchangeability and reliable performance in metric assemblies.
• Compliance with environmental regulations including RoHS 3 and REACH, making them suitable for global industrial supply chains.

Professional Applications & Engineering Value

This M10 socket head cap screw is engineered to address critical challenges in machinery, automotive, and heavy equipment sectors. The black-oxide alloy steel construction combats rust and wear, while the Class 12.9 strength (170,000 PSI tensile, Rockwell C37 hardness) prevents failure under dynamic loads and vibrations. The coarse metric thread (1.5 mm pitch) ensures rapid installation and superior holding power in metals and composites. With a partially threaded design, it allows precise clamping in assemblies where unthreaded shank alignment is crucial. Ideal for high-torque applications using an 8 mm hex key, this screw meets DIN 912 specifications for dimensional consistency, reducing downtime and maintenance costs in industrial fastening systems.

Specification Summary & Compliance

This screw features M10 x 1.5 mm coarse metric threads with a Class 5g6g thread fit for precise tolerance, a minimum thread length of 32 mm, and an overall length of 85 mm. It conforms to DIN 912 for socket head cap screws, ensuring standardized dimensions and performance. The product is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, adhering to strict environmental and safety regulations for industrial use.
