Professional Applications & Engineering Value

This 316 stainless steel flat head screw delivers exceptional value in corrosive or marine environments where standard fasteners fail. The passivated finish creates an additional protective oxide layer, significantly enhancing the natural corrosion resistance of 316 stainless steel. Engineered with fully threaded M6x1mm coarse threads and Class 6g precision, these screws provide superior pull-out resistance in soft materials and faster installation in production settings. The standard flat head profile with 90° countersink ensures flush mounting in precision assemblies, while the slotted drive accommodates both manual and automated installation processes. Ideal for chemical processing equipment, marine hardware, food processing machinery, and outdoor structures requiring reliable, corrosion-resistant fastening solutions that maintain integrity under continuous exposure to moisture, chemicals, and temperature variations.

Specification Summary & Compliance

Manufactured to DIN 963 specifications with Class 6g thread fit ensuring dimensional accuracy and interchangeability. The M6x1mm coarse thread with right-hand direction provides optimal performance in various substrates. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming environmental responsibility and restricted substance adherence. The combination of 316 stainless steel material and passivated finish delivers consistent performance while meeting international standards for industrial fasteners.
