Professional Applications & Engineering Value

These No. 6 x 5/8" zinc-plated steel tapping screws are engineered specifically for sheet metal fastening applications where reliability and efficiency are paramount. The thread forming technology eliminates the need for pre-tapped holes, reducing installation time and labor costs while creating strong, permanent threads that resist vibration loosening. The Phillips flat head design with standard 82° countersink angle provides a flush finish that prevents snagging and maintains aerodynamic surfaces in HVAC systems, electronic enclosures, and automotive panels. The zinc-plated steel construction offers excellent corrosion protection, making these thread forming screws ideal for both indoor and outdoor industrial environments where moisture or chemical exposure may occur.

Specification Summary & Compliance

These tapping screws feature precision No. 6 size with 0.138" thread diameter and 18 threads per inch in right-hand orientation. The A/AB screw type follows industry-standard thread forming specifications with full threading along the 5/8" length. Compatible with No. 32 drill bits (0.116" diameter) for optimal hole preparation in materials up to 0.025" thickness. Manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and workplace safety standards.
