• Environmental compliance meets RoHS 3 and REACH standards for safe use in regulated industries

Professional Applications & Engineering Value

This 316 stainless steel tapping screw delivers exceptional engineering value in sheet metal applications where corrosion resistance and structural integrity are critical. The thread forming design (A/AB type) eliminates the need for separate tapping operations, reducing assembly time and labor costs while creating strong, vibration-resistant connections. The combination of fully threaded construction and pointed tip ensures quick starts and smooth penetration through metal substrates up to 0.025" thickness. The Phillips drive system provides reliable torque transmission during installation, minimizing cam-out incidents that can damage fastener heads. These industrial screws are particularly valuable in HVAC systems, electronic enclosures, and architectural metalwork where exposure to moisture, chemicals, or temperature variations demands the superior performance of 316 stainless steel.

Specification Summary & Compliance

This No. 10 tapping screw features precise dimensional specifications including 0.19" thread diameter, 12 threads per inch, and 3-1/2" length with standard inch system measurements. The fastener conforms to A/AB thread forming standards for sheet metal applications and requires No. 21 drill bit (0.159" diameter) for proper installation. Manufacturing and material compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and restricted substance adherence for industrial use.
