S-90128A332 M4 x 15 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 zinc-plated alloy steel construction prolongs service life in harsh industrial environments.
• High hardness rating (Rockwell C37) provides excellent wear resistance and maintains thread integrity under repeated use.
• Precision hex drive design with 3mm drive size allows for secure tool engagement and easy installation in confined spaces.
• Coarse thread pitch (0.7mm) enables quick assembly and reduces cross-threading risks in demanding applications.
• Full threading along the 15mm length offers maximum grip and uniform load distribution across connected components.
• Compliance with international standards including DIN 912/ISO 4762 ensures consistent quality and interchangeability.

Professional Applications & Engineering Value

These M4 socket head cap screws are engineered to address critical challenges in high-stress industrial applications such as machinery assembly, automotive systems, and precision equipment. The zinc-plated alloy steel construction combats corrosion effectively, extending component lifespan in environments exposed to moisture or chemicals. With a Class 12.9 strength rating and 170,000 psi tensile strength, they prevent stripping and shearing under heavy loads, while the standard socket head profile and 3mm hex drive facilitate secure tightening in limited-access areas. The coarse metric thread (M4 x 0.7mm) ensures rapid installation and reliable holding power, making them ideal for applications demanding both durability and efficient assembly.

Specification Summary & Compliance

This screw features M4 x 0.7mm coarse threads with a Class 5g6g thread fit per ISO standards, ensuring precise dimensional accuracy and compatibility. It is manufactured in accordance with DIN 912 / ISO 4762 specifications for socket head cap screws and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming environmental and safety adherence. The 15mm fully threaded length and right-hand thread direction provide consistent performance, backed by the high-strength Class 12.9 rating for demanding engineering use.
