Professional Applications & Engineering Value
This thread cutting tapping screw delivers exceptional value in metal and sheet metal fabrication where corrosion resistance and installation efficiency are critical. The 18-8 stainless steel construction combined with Type C thread cutting technology enables direct installation without pilot holes, significantly reducing assembly time and labor costs. The fully threaded design with pointed tip ensures immediate bite and continuous thread formation, preventing material displacement in thin-gauge applications. The oval head with Phillips drive provides both aesthetic flush mounting and reliable torque transmission, making it ideal for industrial equipment, enclosures, and automotive components requiring durable, vibration-resistant fastening solutions.
Specification Summary & Compliance
This M3.5 x 38mm metric tapping screw features precision right-hand threads with 0.14" thread diameter and full threading along its length. Manufactured to DIN 7983 specifications (equivalent to ISO 7051), it ensures dimensional accuracy and interchangeability. The screw demonstrates full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmental safety and material sustainability.
