S-91292A276 M20 x 120 mm DIN 912, ISO 4762 18-8 Stainless Steel Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with 18-8 Stainless Steel construction, ideal for harsh industrial environments.
• High tensile strength of 70,000 psi ensures reliable load-bearing capacity and reduces failure risks.
• Partially threaded design provides secure clamping where full thread engagement isn't required, optimizing installation time.
• Precise Class 6g thread fit guarantees smooth assembly and consistent performance in metric applications.
• Standard hex socket drive (17mm) allows for high torque application with common tools, minimizing slippage.
• Compliance with DIN 912/ISO 4762 standards ensures dimensional accuracy and interchangeability in global markets.
• RoHS 3 and REACH environmental compliance meets regulatory requirements for safe, sustainable usage.

Professional Applications & Engineering Value

This M20 x 2.5 mm coarse thread Socket Head Cap Screw is engineered to address common industrial challenges such as vibration loosening and material degradation. The 18-8 Stainless Steel offers excellent resistance to rust and chemicals, making it suitable for machinery, automotive assemblies, and outdoor equipment where exposure to moisture is a concern. The partially threaded rod design allows the unthreaded portion to act as a precision pilot, reducing cross-threading risks during high-speed assembly. With a 30mm head diameter and standard socket head profile, it provides a flush finish in counterbored holes while enabling deep socket engagement for secure fastening in confined spaces, enhancing overall structural integrity and maintenance efficiency.

Specification Summary & Compliance

This screw features a metric M20 thread with 2.5 mm coarse pitch and Class 6g thread fit per ISO standards, ensuring precise dimensional tolerances. It is manufactured to meet DIN 912 (identical to ISO 4762) specifications for socket head cap screws, covering head dimensions, drive size, and mechanical properties. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted hazardous substances for safe industrial use.
