S-91502A132 M4 x 35 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 blue-dyed zinc plating protects against harsh environments, extending service life and reducing maintenance needs.
• High hardness rating (Rockwell C37) provides excellent wear resistance, maintaining thread integrity and drive engagement over repeated use.
• Precise Class 5g6g thread fit guarantees smooth assembly and secure fastening, minimizing the chance of cross-threading or loosening.
• Compact socket head design with 3 mm hex drive allows for easy installation in confined spaces using standard tools.
• Partially threaded shank offers optimal grip and clamping force control, ideal for applications requiring precise joint compression.
• Compliance with DIN 912/ISO 4762 standards ensures dimensional accuracy and interchangeability, facilitating global sourcing and replacement.

Professional Applications & Engineering Value

Engineered for demanding industrial environments, these M4 socket head cap screws address critical challenges in machinery assembly, automotive systems, and precision equipment. The alloy steel construction combined with a Class 12.9 strength rating provides a robust solution for high-vibration and heavy-load scenarios, preventing joint failure and downtime. The blue-dyed zinc-plated finish not only enhances corrosion resistance but also allows for easy visual identification in complex assemblies. With a coarse thread pitch (0.7 mm) and right-hand thread direction, these screws ensure quick installation and reliable holding power, making them ideal for industrial fasteners in automated production lines and structural frameworks where durability and compliance with international standards are paramount.
