S-90356A259 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with Black Oxide 18-8 Stainless Steel construction for extended service life in harsh environments
• Effortless installation with Phillips drive and thread-forming design that eliminates the need for pre-tapped holes in sheet metal
• Optimal material displacement through the pointed tip and fully threaded design ensures secure, vibration-resistant fastening
• Precise compatibility with No. 29 drill bits (0.136" diameter) for accurate hole preparation in sheet metal up to 0.025" thickness
• Enhanced grip and distribution from the pan head design provides superior clamping force without sinking into materials
• Industry compliance assurance with RoHS 3 and REACH regulations for safe, environmentally responsible manufacturing
• Reliable thread engagement with 15 threads per inch and right-hand threading for consistent performance in automated assembly

Professional Applications & Engineering Value

These Black Oxide 18-8 Stainless Steel tapping screws deliver exceptional value in sheet metal applications where corrosion resistance and installation efficiency are critical. The thread forming design creates stronger, more durable threads in parent materials by cold-forming rather than cutting, eliminating chip accumulation issues in automated production lines. The combination of Phillips drive and pan head profile ensures reliable torque transmission while distributing clamp load effectively across thinner gauge materials. With fully threaded No. 8-15 specification and precise No. 29 drill bit compatibility, these screws provide consistent performance in HVAC systems, electronic enclosures, and industrial equipment where vibration resistance and environmental durability are paramount.

Specification Summary & Compliance

This No. 8-15 x 1/2" tapping screw features a 0.164" thread diameter with 15 threads per inch in right-hand direction, manufactured to Class 2A thread tolerance for reliable engagement. The A/AB tapping screw type follows industry-standard thread forming specifications for sheet metal applications. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and workplace safety standards are met for industrial distribution and use.
