S-90048A028 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-term durability in harsh industrial environments.
• Efficient thread forming design with 52 TPI and pointed tip for clean, secure fastening without pre-tapping in sheet metal up to 0.025" thickness.
• Optimal flush installation thanks to the standard flat head profile and 82° countersink angle, reducing snagging and improving aesthetics.
• Reliable drive engagement with Phillips No. 0 drive style, minimizing cam-out and enabling consistent torque application.
• Versatile A/AB type compatibility for a wide range of sheet metal applications, ensuring consistent performance and reduced inventory needs.
• Full threading and right-hand direction for maximum grip and uniform load distribution across the entire screw length.
• Precision-matched installation with No. 55 drill bit compatibility, streamlining assembly and minimizing errors.

Professional Applications & Engineering Value

This No. 0 Phillips flat head tapping screw is engineered for demanding sheet metal applications, where precision and reliability are critical. The zinc-plated steel material provides excellent corrosion resistance, extending service life in environments exposed to moisture or chemicals. Its thread forming (A/AB type) design creates strong, permanent threads in ductile materials without chips, eliminating the need for separate tapping operations and reducing assembly time. The 82° countersink angle and flat head ensure a flush finish, preventing interference in tight spaces. With a fully threaded shank and 52 TPI, it delivers superior holding power in thin materials up to 0.025" thick, making it ideal for HVAC, electronics enclosures, and automotive panels where vibration resistance and seamless installation are paramount.

Specification Summary & Compliance

This screw adheres to standard inch measurements with a No. 0 screw size, 1/2" length, and right-hand thread direction. It meets typical industry tolerances for thread forming screws, including compatibility with No. 55 drill bits (0.052" diameter) and an 82° countersink angle. The zinc-plated steel construction complies with RoHS and REACH environmental standards, ensuring safe use in various industrial sectors. Manufactured to consistent quality standards for reliable performance in sheet metal fastening applications.
