Professional Applications & Engineering Value

These No. 8 oval head tapping screws are engineered to address common challenges in metalworking and construction, such as time-consuming pre-drilling and fastener failure due to corrosion. The 18-8 stainless steel material offers excellent resistance to rust and oxidation, ideal for outdoor or humid conditions. With a thread forming (BSD type) design and self-drilling tip, they create precise, strong threads in steel and sheet metal up to 0.1" thick, reducing labor costs and improving assembly efficiency. The fully threaded right-hand configuration ensures consistent clamping force, while the Phillips drive facilitates quick installation in automated or manual settings, making them a reliable choice for HVAC, automotive, and structural applications.

Specification Summary & Compliance

This product adheres to standard inch measurements with a thread diameter of 0.164" and approximately 18 threads per inch, ensuring compatibility with common industrial specifications. The screws feature a standard oval head profile with an 82° countersink angle and are manufactured as thread forming tapping screws (BSD type). Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations confirms they are free from hazardous substances, supporting safe and sustainable usage in various sectors.
