DIN7982 Cross Recessed Countersunk Head Tapping Screws
DIN 7982 cross recessed countersunk head tapping screws feature a flat countersunk head and a cross-shaped drive recess. The head sits flush with the surface when installed in a suitably countersunk hole, making these screws suitable for sheet metal panels, electrical enclosures, metal covers, and equipment housings. Their self-tapping threads form mating threads in suitable materials, providing a practical fastening solution for sheet metal and other thin-walled components.
As an ISO 9001-certified company, we supply DIN 7982 tapping screws to meet different dimensional, material, and application requirements. Product specifications can be tailored to the required screw dimensions, steel or stainless steel grades, and surface finishes. We work with qualified production partners to coordinate manufacturing, heat treatment, and quality inspection according to the agreed technical requirements.

Mechanical Property:
Steel DIN 7982 Tapping Screws – ISO 2702
During installation, DIN 7982 steel tapping screws must withstand the torque applied through the cross recess while forming threads in the base material. Adequate torsional strength and hardness help reduce the risk of screw fracture or drive recess damage during tightening. ISO 2702 specifies the mechanical and physical requirements for heat-treated steel tapping screws.
Stainless Steel DIN 7982 Tapping Screws – ISO 3506-4
For stainless steel DIN 7982 tapping screws, torsional strength is important for reliable installation, particularly when the screw forms threads in the base material. Mechanical performance depends on the stainless steel grade and applicable product requirements. ISO 3506-4 specifies the mechanical and physical requirements for corrosion-resistant stainless steel tapping screws.
