Professional Applications & Engineering Value
This No. 12 sheet metal tapping screw delivers exceptional engineering value through its thread forming technology that eliminates the common problem of loose fasteners in thin materials. The flanged hex head design provides superior clamping force while preventing pull-through in sheet metal applications up to 0.025" thickness. The fully threaded construction with 11 TPI and pointed tip ensures rapid installation without pre-tapping, significantly reducing assembly time in industrial manufacturing. Engineered specifically for sheet metal fastening, this screw creates strong, permanent threads that resist vibration loosening, making it ideal for HVAC systems, electrical enclosures, automotive components, and machinery assemblies where reliability is critical.
Specification Summary & Compliance
This thread forming tapping screw features precise dimensional specifications including No. 12 size (0.216" thread diameter), 1/2" length, 11 TPI right-hand threads, and fully threaded shank. The external hex/slotted drive with 0.313" head width and integrated 0.432" flange diameter ensures secure installation. Manufactured to industry standards for Type A tapping screws, this product complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting the latest environmental and safety requirements for industrial fasteners.
