S-91290A938 M36 x 130 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 provided by the black-oxide coating on alloy steel, extending service life in demanding environments
• Precise torque transmission through the 27mm hex drive and standard socket head profile, ensuring secure installation and removal
• Optimized thread engagement with M36 coarse thread (4mm pitch) and Class 5g6g fit, enabling faster assembly and reduced cross-threading risk
• Enhanced durability with Rockwell C37 hardness, maintaining structural integrity under repeated loading cycles
• Versatile partial threading (84mm thread length on 130mm body) allowing for both clamping and alignment functions in complex assemblies
• Industry-standard compatibility meeting DIN 912/ISO 4762 specifications for seamless integration into existing metric systems

Professional Applications & Engineering Value

This M36 socket head cap screw delivers critical engineering solutions for heavy machinery, industrial equipment, and structural applications where high tensile strength and reliability are paramount. The black-oxide alloy steel construction combined with Class 12.9 strength rating (170,000 psi tensile) withstands extreme vibrational forces and dynamic loads common in manufacturing environments. The coarse metric thread (4mm pitch) ensures rapid assembly in thick materials while the partially threaded design provides unthreaded shank sections for precise component alignment. With 54mm head diameter and 36mm head height, it offers substantial bearing surface for distributed load transfer, making it ideal for construction equipment, pressing machinery, and heavy-duty industrial assemblies requiring DIN 912/ISO 4762 compliance.

Specification Summary & Compliance

This socket head cap screw maintains Class 5g6g thread tolerance per metric standards with M36 x 4mm coarse thread configuration and 84mm minimum thread length. Manufactured to DIN 912 ISO 4762 specifications, ensuring dimensional accuracy and interchangeability. The fastener is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant (including SVHC requirements as of 01/17/2023), meeting international environmental and safety regulations for industrial components.
