S-91290A944 M36 x 180 mm DIN 912, ISO 4762 Alloy Steel Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength of 170,000 psi ensures reliable performance in high-stress applications, reducing the risk of fastener failure.
• Superior corrosion resistance from the black-oxide finish on alloy steel extends service life in harsh industrial environments.
• High hardness rating (Rockwell C37) provides excellent wear resistance, maintaining thread integrity through repeated use.
• Precise hex drive (27mm) allows for secure tool engagement and high torque application without stripping.
• Class 12.9 strength classification guarantees consistent mechanical properties for critical assembly requirements.
• Partially threaded design offers optimal grip length for clamping while minimizing thread exposure in non-engaged sections.
• Compliance with DIN 912/ISO 4762 standards ensures dimensional accuracy and interchangeability in global engineering projects.

Professional Applications & Engineering Value

This M36 socket head cap screw delivers exceptional engineering value in demanding applications where reliability is non-negotiable. Manufactured from black-oxide alloy steel, it provides superior corrosion protection for machinery, heavy equipment, and structural assemblies exposed to challenging environments. The coarse 4mm pitch metric thread ensures rapid installation and secure fastening in high-vibration settings, while the Class 12.9 strength rating withstands extreme tensile and dynamic loads. The standard socket head profile with 27mm hex drive accommodates high-torque applications without cam-out, making it ideal for precision assembly in automotive, construction, and industrial manufacturing sectors where DIN 912/ISO 4762 compliance is mandatory for quality assurance.

Specification Summary & Compliance

This socket head cap screw features M36x4mm metric coarse threads with Class 5g6g thread fit tolerance, ensuring precise engagement and dimensional consistency. The partially threaded design provides 84mm minimum thread length on a 180mm overall length, manufactured to DIN 912/ISO 4762 specifications for dimensional accuracy. The product fully complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting international environmental and safety standards for industrial fastener applications.
