S-90048A148 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Efficient thread forming capability creates permanent, secure threads in sheet metal without requiring pre-tapped holes
• Optimal flush mounting with standard flat head profile and 82° countersink angle for smooth surface finishes
• Enhanced driving efficiency through Phillips No. 2 drive design that minimizes cam-out during installation
• Maximum thread engagement with fully threaded shank design ensuring superior holding power across the entire fastener length
• Precision compatibility with No. 32 drill bit (0.116") for accurate hole preparation and secure fastening in 0.025" maximum thickness materials
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for environmentally responsible manufacturing

Professional Applications & Engineering Value

These No. 6 x 1/2" zinc-plated steel tapping screws deliver exceptional performance in sheet metal applications where traditional fastening methods fall short. The thread forming design eliminates the need for separate tapping operations, significantly reducing assembly time and labor costs. The A/AB tapping screw type with right-hand threading and 18 threads per inch creates strong, reliable connections in thin-gauge materials up to 0.025" thickness. The Phillips flat head configuration with standard profile ensures flush mounting without protruding hardware, while the pointed tip facilitates precise alignment and easier starting. These fully threaded screws maintain consistent engagement throughout the material thickness, providing superior pull-out resistance and vibration resistance in HVAC systems, electronic enclosures, and automotive components.

Specification Summary & Compliance

These thread forming screws feature precise dimensional accuracy with 0.138" thread diameter and 18 threads per inch following standard inch system specifications. The flat head design incorporates an 82° countersink angle for proper seating in prepared holes. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and workplace safety. The zinc-plated steel construction provides reliable corrosion protection while maintaining the mechanical strength required for demanding sheet metal fastening applications.
