S-90048A020 Length 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring longevity in demanding industrial environments
• Effortless installation through thread forming technology that creates strong, permanent threads without pre-tapping
• Maximum holding power with 52 threads per inch precision and 82° countersink angle for secure sheet metal fastening
• Complete flush mounting with standard flat head profile that sits perfectly flush with material surfaces
• Enhanced driving efficiency with Phillips No. 0 drive that prevents cam-out and ensures consistent torque application
• Full-length fastening capability with completely threaded shank for maximum grip along the entire 1/4" length
• Optimized for thin materials with 0.025" maximum drilling thickness capability for precision sheet metal work

Professional Applications & Engineering Value

These No. 0 Phillips flat head tapping screws deliver exceptional engineering value in sheet metal applications where vibration resistance and permanent fastening are critical. The thread forming technology eliminates the need for separate tapping operations, reducing assembly time and labor costs while creating stronger thread engagement than traditional cutting screws. Made from zinc-plated steel, these screws provide reliable corrosion protection in environments where moisture or chemical exposure is a concern. The 82° countersink angle ensures perfect flush mounting in precision metalwork, while the 52 threads per inch configuration delivers maximum holding power in thin-gauge materials. Ideal for HVAC systems, electronic enclosures, automotive components, and industrial machinery where secure, permanent fastening in sheet metal is essential for structural integrity and long-term performance.

Specification Summary & Compliance
