Professional Applications & Engineering Value

Engineered for industrial and mechanical assemblies, these M4 flat head screws in 316 Stainless Steel address critical needs for corrosion resistance and structural integrity. The coarse 0.7mm pitch thread and Class 6g tolerance facilitate quick, reliable fastening in metals and plastics, reducing assembly time while preventing cross-threading. The passivated finish further extends service life in moist or chemically aggressive settings, such as marine equipment, food processing machinery, and outdoor structures. With a 90° countersink angle and hex drive, they provide a flush, tamper-resistant fit, making them ideal for applications where surface profile and security are paramount.

Specification Summary & Compliance

This fully threaded screw adheres to DIN 7991 specifications, with a thread size of M4 x 0.7mm, length of 30mm, and Class 6g thread fit for precise metric tolerances. The head diameter is controlled within -0.36 to 0 mm tolerance, ensuring consistent countersinking. It is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting stringent environmental and safety regulations for industrial use.
