Professional Applications & Engineering Value

These black-oxide steel tapping screws are engineered to address common challenges in sheet metal assembly, such as material splitting and loose fasteners. The thread forming design creates strong, permanent threads without cutting away material, which preserves the integrity of thin-gauge metals and enhances joint strength. The Phillips pan head offers a low-profile, flush finish while the fully threaded shank with a pointed tip ensures quick starts and consistent engagement. Ideal for HVAC, electronics enclosures, and automotive panels, these screws reduce installation time and improve reliability in high-vibration settings, making them a go-to choice for industrial fastening solutions.

Specification Summary & Compliance

This product adheres to standard inch measurements with a thread diameter of 0.164" and approximately 15 threads per inch, ensuring precise fit in pre-drilled holes. It conforms to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, affirming its suitability for regulated industries. The screw is designed for use with a No. 29 drill bit and supports a maximum drilling thickness of 0.025", providing reliable performance in sheet metal applications with consistent thread engagement and right-hand threading for standard assembly procedures.
