S-92290A856 M4 x 65 mm DIN 912, ISO 4762 Super-Corrosion-Resistant 316 Stainless Steel Socket Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction and passivated finish, ideal for harsh industrial environments and chemical exposure.
• High tensile strength of 70,000 psi ensures reliable performance under significant mechanical loads and vibration.
• Precise hex socket drive (3mm) allows for secure tool engagement, reducing the risk of stripping and enabling high-torque installation.
• Partially threaded design (20mm thread length) provides a firm grip in the threaded section while the smooth shank allows for precise alignment.
• Standardized coarse thread (M4 x 0.7mm) with Class 6g fit ensures quick assembly, easy engagement, and consistent performance.
• Compliance with DIN 912/ISO 4762 standards guarantees dimensional accuracy, interchangeability, and global engineering acceptance.
• RoHS 3 and REACH compliance ensures the fastener meets stringent environmental and safety regulations for modern manufacturing.

Professional Applications & Engineering Value

This M4 socket head cap screw is engineered to solve critical challenges in machinery assembly, automotive components, and marine equipment. The 316 stainless steel material, combined with a passivated finish, provides exceptional resistance to pitting and crevice corrosion, making it suitable for applications exposed to moisture, chemicals, and salt spray. The coarse thread design (M4 x 0.7mm) facilitates rapid installation and reduces cross-threading risks in high-volume production lines. Its partially threaded configuration ensures that the unthreaded shank bears against the joint, providing superior shear strength and alignment stability. The hex drive allows for flush mounting in confined spaces, which is vital for maintaining sleek designs in enclosures and precision instruments. These features collectively enhance assembly efficiency, reduce maintenance downtime, and extend the service life of the final product.

Specification Summary & Compliance
