S-91290A956 M36 x 240 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 coating extends service life in harsh industrial environments, minimizing maintenance needs.
• High hardness rating (Rockwell C37) provides excellent wear resistance, maintaining thread integrity over repeated use.
• Precision thread fit (Class 5g6g) allows for smooth assembly and secure fastening, reducing installation time and improving joint reliability.
• Partially threaded design offers optimal grip and clamping force control, ideal for applications requiring precise load distribution.
• Standard hex socket drive (27 mm) enables easy installation with common tools, enhancing efficiency in tight spaces.
• Compliance with international standards (DIN 912/ISO 4762) ensures interchangeability and quality consistency across global projects.

Professional Applications & Engineering Value

This M36 socket head cap screw is engineered to address critical challenges in heavy-duty machinery, construction, and automotive assembly. The Class 12.9 high-strength alloy steel core, combined with a coarse thread (4 mm pitch), provides superior resistance to vibration loosening and dynamic loads, common in industrial settings. The black-oxide surface treatment not only enhances corrosion resistance but also reduces friction during installation, preventing galling. With a partially threaded rod and precise metric thread specifications, it ensures secure clamping in bolted joints, minimizing the risk of fatigue failure. Ideal for use in high-stress applications like engine mounts, structural frames, and heavy equipment, this screw delivers long-term reliability and reduces downtime.

Specification Summary & Compliance
