ISO14585 Torx Pan Head Self Tapping Screws
ISO 14585 Torx Pan Head Self Tapping Screws are precision fasteners manufactured according to ISO 14585 standards, featuring a pan head design and hexalobular (Torx) drive system. The Torx drive provides improved torque transmission, better tool engagement and reduced risk of cam-out during installation compared with traditional cross recess drives. With their self-tapping thread design, these screws can create their own threads when installed into suitable materials, providing efficient and reliable fastening without the need for pre-tapped holes.
Manufactured from stainless steel, carbon steel or other suitable materials, ISO 14585 Torx Pan Head Self Tapping Screws offer excellent fastening performance, dimensional accuracy and consistent quality. The pan head provides a larger bearing surface, while the sharp tapping thread ensures secure engagement in materials such as sheet metal, plastics and other components. These screws are widely used in electrical equipment, automotive parts, machinery, appliances and industrial assemblies where fast and reliable installation is required.

Mechanical Property:
Steel ISO 14585 Self-Tapping Screws – ISO 2702
During installation, ISO 14585 steel self-tapping screws must withstand tightening torque while forming threads in the base material. Adequate torsional strength and hardness help reduce the risk of screw breakage or damage to the drive recess. ISO 2702 specifies the mechanical and physical requirements for heat-treated steel tapping screws.
Stainless Steel ISO 14585 Self-Tapping Screws – ISO 3506-4
For stainless steel ISO 14585 self-tapping screws, torsional strength and thread-forming ability are important for reliable installation. The screws must form mating threads in suitable materials without premature breakage or excessive deformation. ISO 3506-4 specifies the mechanical and physical requirements for corrosion-resistant stainless steel tapping screws.
