S-91274A117 M4 x 10 mm ASTM B117, 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 under high-stress conditions, reducing the risk of fastener failure in demanding applications.
• Superior corrosion resistance from the zinc-flake coating protects against harsh industrial environments, extending service life and reducing maintenance needs.
• High hardness (Rockwell C37) provides excellent wear resistance and durability, maintaining thread integrity through repeated assembly and disassembly.
• Precision Class 5g6g thread fit guarantees smooth installation and secure fastening, minimizing play and vibration loosening in machinery.
• Standard hex socket drive (3mm) allows for easy installation with common tools, improving assembly efficiency and reducing labor time.
• Fully threaded design offers consistent clamping force along the entire length, ideal for applications requiring uniform pressure distribution.
• Compliance with DIN 912 and ISO 4762 ensures dimensional accuracy and interchangeability, providing peace of mind for OEM and MRO specifications.

Professional Applications & Engineering Value

Engineered for high-performance industrial applications, these M4 socket head cap screws address critical challenges in machinery, automotive, and heavy equipment assembly. The zinc-flake-coated alloy steel construction delivers robust corrosion resistance, essential for operations exposed to moisture, chemicals, or outdoor elements. With a Class 12.9 strength rating and coarse metric thread (0.7mm pitch), they provide superior clamping force and vibration resistance, preventing joint failure in dynamic loads. The right-hand thread and standard hex drive facilitate quick installation, reducing downtime in production lines. Ideal for precision engineering where mechanical reliability and compliance with international standards are non-negotiable, these screws ensure long-term operational integrity in critical fastening points.
