Professional Applications & Engineering Value

These M6.3 metric tapping screws deliver exceptional engineering value through their zinc-plated steel construction and thread forming technology, specifically engineered to eliminate the need for separate tapping operations in industrial assembly. The specialized drill tip with 12mm length enables direct penetration into materials up to 6mm thick, significantly reducing installation time and labor costs in steel, stainless steel, aluminum, and sheet metal applications. The fully threaded design ensures maximum pull-out resistance and load distribution, while the Phillips drive provides reliable torque transfer during high-volume production. Ideal for construction, manufacturing, and metal fabrication, these screws solve critical fastening challenges by combining drilling and tapping operations into a single, efficient process that maintains structural integrity across diverse material types.

Specification Summary & Compliance

Manufactured to DIN 7504 N standards with metric thread specifications and precise dimensional tolerances, these tapping screws feature M6.3 size with approximate 1.8mm thread pitch and 45mm length. The thread forming design creates secure fastening without material removal, while the pan head configuration with Phillips No. 3 drive ensures consistent installation. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, guaranteeing safe use in industrial applications while meeting international quality standards for reliable performance in demanding conditions.
