Professional Applications & Engineering Value

These 18-8 stainless steel tapping screws deliver exceptional engineering value in sheet metal applications where reliable sealing is critical. The thread forming design eliminates the need for pre-tapped holes while creating stronger, more vibration-resistant connections. The integrated rubber O-ring provides a permanent seal against moisture, dust, and contaminants, solving common leakage issues in HVAC systems, electronic enclosures, and industrial equipment. The combination of Phillips drive and pan head configuration ensures straightforward installation with standard tools, while the fully threaded design maximizes grip length and holding power. Engineered for demanding environments, these screws maintain their sealing integrity across a broad temperature range from -40° to 225°F, making them ideal for outdoor applications and temperature-fluctuating environments.

Specification Summary & Compliance

This No. 6-20 x 1/2" tapping screw features precision right-hand threads with approximately 20 threads per inch and requires a No. 32 drill bit (0.116" diameter) for proper installation. The screw meets industry standards for thread forming Type B applications and is manufactured with fully threaded configuration for maximum engagement. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and safety in industrial applications.
