S-90190A153 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments.
• Efficient installation and reduced assembly time using a standard No. 2 Phillips drive, minimizing tool slippage.
• Excellent thread-forming capability in sheet metal up to 0.025" thickness, creating strong, reliable threads without pre-tapping.
• Secure and flush fastening with a rounded pan head design, providing a low-profile finish and good bearing surface.
• High pull-out resistance and vibration resistance due to the fully threaded, pointed tip design and 18 threads per inch.
• Wide compatibility with standard No. 32 drill bits (0.116" diameter) for precise hole preparation.
• Environmental compliance assurance meeting RoHS 3 and REACH standards, suitable for regulated industries.

Professional Applications & Engineering Value

These No. 6 x 1" zinc-plated steel tapping screws are engineered specifically for sheet metal applications, where reliable fastening is critical. The thread-forming design (Type A/AB) displaces material to create strong, permanent threads, eliminating the need for separate tapping operations and reducing assembly costs. The Phillips pan head ensures easy drive engagement and a clean appearance, while the fully threaded shank with a pointed tip facilitates quick starts and consistent penetration. Made from zinc-plated steel, they resist corrosion in various industrial settings, providing long-term durability and maintaining clamp force under vibration. Ideal for HVAC, electronics enclosures, and automotive assemblies, these screws deliver consistent performance where precision and holding power are paramount.

Specification Summary & Compliance

This thread-forming sheet metal screw features a No. 6 size with 0.138" thread diameter and 18 threads per inch in a right-hand direction. The screw is 1" long with a fully threaded round shank and standard pan head (0.27" diameter, 0.097" height). It is designed for use with a No. 32 drill bit (0.116" diameter) in materials up to 0.025" thickness. Manufactured to industry standards for tapping screw Type A/AB, it is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations.
