ISO 14585:2011 Pan Head Torx Tapping Screw

ISO 14585:2011 Pan Head Torx Tapping Screw combines a pan head with a Torx drive, offering good bearing contact and stable torque transmission. It is suitable for automated assembly and applications where drive recess damage needs to be controlled.

The Torx drive reduces the risk of cam-out and improves consistency during continuous installation. The tapping thread is suitable for pilot holes in thin metal, plastic, and light materials, while the pan head provides a larger bearing surface to help protect the fastened part.

This product can be used in electronic equipment, automotive interiors, appliances, plastic housings, light frames, and industrial panels. Zinc plating, stainless steel, or other surface treatments can be selected for corrosion resistance, appearance, and high-volume assembly needs.
