S-90053A148 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Corrosion-resistant zinc-plated steel construction ensures long-lasting performance in demanding industrial environments, reducing replacement costs.
• Thread forming design creates strong, permanent threads in sheet metal without chips, improving joint integrity and vibration resistance.
• Slotted pan head with standard rounded profile allows for easy installation with common tools while providing a low-profile, secure fastening surface.
• 18 TPI precision threading and pointed tip enables quick, accurate starts and smooth driving, minimizing installation time and material stress.
• Fully threaded No. 6 shank delivers maximum grip length and holding power in thin sheet metal applications up to 0.025" thickness.
• Compatible with standard No. 32 drill bits (0.116") simplifies hole preparation and ensures proper fit for reliable, stripped-free installations.
• RoHS 3 and REACH compliance guarantees environmentally safe manufacturing and use, meeting global regulatory requirements for industrial components.

Professional Applications & Engineering Value

These zinc-plated steel tapping screws are engineered specifically for sheet metal applications where vibration resistance and material integrity are critical. The thread forming A/AB type design displaces metal rather than cutting it, creating zero chips and stronger thread engagement that won't loosen under stress. This makes them ideal for assembly lines, HVAC systems, electronic enclosures, and automotive components where reliable fastening is essential. The combination of 18 TPI right-hand threading with a pointed tip ensures quick penetration and reduced driving torque, while the slotted pan head provides ample surface contact for secure clamping without sinking into softer materials.

Specification Summary & Compliance

This No. 6 x 1/2" tapping screw features standard Class 2A thread tolerances with fully threaded round shank design for consistent performance. Manufactured to A/AB tapping screw specifications for thread forming applications in sheet metal, it requires a No. 32 drill bit (0.116" diameter) for proper installation in materials up to 0.025" thickness. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global industrial markets.
