Professional Applications & Engineering Value
These 316 stainless steel tapping screws deliver exceptional performance in demanding sheet metal applications where corrosion resistance and reliable fastening are critical. The thread forming design eliminates the need for separate tapping operations, creating strong, permanent threads that resist vibration loosening in thin materials. With their fully threaded No. 4 diameter and 24 TPI configuration, these screws distribute clamping force evenly, preventing material distortion while providing maximum pull-out resistance. The Phillips drive system ensures efficient installation in high-volume production environments, while the pan head profile maintains a low-profile appearance without compromising on bearing surface area. Ideal for HVAC systems, electronic enclosures, and industrial equipment where exposure to moisture and chemicals is common.
Specification Summary & Compliance
This No. 4 x 1/2" tapping screw features precision right-hand threads with standard inch measurements and Class 2A thread tolerances. Manufactured to A/AB tapping screw type specifications with fully threaded construction and 24 TPI thread pitch. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and industrial compliance standards are met for global manufacturing applications.
