S-91290A293 M27 x 200 mm DIN 912, ISO 4762 Alloy Steel Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional load-bearing capacity with Class 12.9 strength rating and 170,000 psi tensile strength for reliable performance in high-stress applications.
• Superior corrosion resistance from the black-oxide finish on alloy steel, extending service life in demanding industrial environments.
• High hardness and durability with Rockwell C37 hardness, reducing wear and maintaining thread integrity under repeated use.
• Secure and efficient installation using a standard 19mm hex drive, providing positive torque transfer and reducing tool slippage.
• Optimized thread engagement with M27 x 3mm coarse right-hand threads and Class 5g6g fit, ensuring easy assembly and vibration resistance.
• Versatile partial threading over 66mm, allowing for precise clamping force distribution in varied assembly setups.
• Global compliance and safety meeting DIN 912/ISO 4762 standards, RoHS 3, and REACH regulations for use in international markets.

Professional Applications & Engineering Value

This M27 socket head cap screw is engineered to address critical challenges in heavy machinery, automotive, and construction sectors where high tensile strength and corrosion resistance are paramount. The black-oxide alloy steel construction combats rust and chemical exposure, while the Class 12.9 rating ensures it withstands extreme loads without failure. Its partially threaded design and coarse metric thread simplify alignment in thick materials, reducing installation time and minimizing stress concentration. Ideal for bolting structural frames, engine components, or industrial equipment, this screw provides long-term reliability, backed by ISO 4762 and DIN 912 specifications for consistent quality and performance in B2B procurement scenarios.

Specification Summary & Compliance

This screw features precise Class 5g6g thread fit per metric standards, with a minimum thread length of 66mm and total length of 200mm. It conforms to DIN 912 (identical to ISO 4762) for dimensional accuracy and socket head profile. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) ensures it is free of hazardous substances, supporting safe and sustainable industrial use.
