Key Features & Benefits at a Glance
- Exceptional corrosion resistance in harsh environments due to premium 316 stainless steel construction
- High-strength performance with a tensile strength of 70,000 psi for reliable load-bearing applications
- Space-saving low-profile head design allows for installation in tight or recessed spaces without compromising drive engagement
- Secure hex drive system (2.5mm) provides positive torque transmission and reduces the risk of tool slippage
- Precision Class 6g thread fit ensures consistent, vibration-resistant fastening in coarse thread applications
- Partially threaded shank design offers unthreaded bearing surface for improved shear strength and alignment
- Full regulatory compliance with DIN 7984, RoHS 3, and REACH standards for global industrial use
Professional Applications & Engineering Value
Engineered for demanding environments, these M4 socket head cap screws provide critical solutions where corrosion resistance and space constraints are primary concerns. The 316 stainless steel material offers superior performance in chemical processing, marine, and food-grade applications, resisting pitting and chloride attack better than standard grades. The low-profile socket head design is particularly valuable in compact assemblies and machinery where clearance is limited, while the hex drive ensures high torque capability without cam-out. With their partially threaded configuration and coarse metric thread (M4 x 0.7), these fasteners deliver reliable clamping force in vibration-prone equipment, making them ideal for precision engineering, automotive subsystems, and industrial automation where dimensional stability and regulatory compliance are mandatory.
Specification Summary & Compliance
This low profile socket head cap screw features precise M4 x 0.7 mm coarse threading with Class 6g tolerance for consistent fit. Manufactured to DIN 7984 specifications, it ensures dimensional accuracy and interchangeability. The fastener is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting the latest environmental and safety standards for industrial components.
