Professional Applications & Engineering Value
This M4 low profile socket head cap screw in 316 stainless steel addresses critical engineering challenges in compact assemblies where space optimization and corrosion resistance are paramount. The low-profile head minimizes protrusion, making it ideal for machinery, electronics, and automotive components where flush mounting is required. Its coarse metric thread (M4 x 0.7mm) facilitates quick installation and reduces cross-threading risks, while the fully threaded design ensures consistent clamping force across the entire length. The hex socket drive provides reliable torque transmission, preventing stripping during high-torque applications. Engineered to DIN 7984 standards, this fastener delivers predictable performance in industrial settings, from marine equipment to food processing machinery, where durability and regulatory compliance are non-negotiable.
Specification Summary & Compliance
This metric socket head cap screw features M4 x 0.7mm coarse threads with Class 6g tolerance for precision fit, a 20mm fully threaded length, and a low-profile head with 2.5mm hex drive. Manufactured in compliance with DIN 7984 specifications, it is RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, ensuring adherence to environmental and safety regulations for industrial use.
