S-90190A168 Length 3/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments.
• Effortless installation via thread forming design that creates strong, permanent threads in sheet metal without pre-tapping.
• High torque transmission with Phillips No. 2 drive, preventing cam-out and ensuring secure fastening in confined spaces.
• Maximum material engagement through fully threaded shank and pointed tip, providing exceptional pull-out resistance in sheet metal applications.
• Precise fit and reliable performance with standardized No. 7 screw size and 16 threads per inch, ensuring consistent results across production runs.
• Wide compatibility with standard No. 30 drill bits (0.1285" diameter), streamlining your assembly process for sheets up to 0.025" thick.
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for safe use in global industrial supply chains.

Professional Applications & Engineering Value

These zinc-plated steel tapping screws deliver exceptional value in sheet metal fabrication and assembly operations. The thread forming technology eliminates the need for separate tapping operations, significantly reducing installation time and labor costs while creating stronger thread engagement than cutting alternatives. The Phillips pan head design provides a low-profile fastener head that sits flush against surfaces, ideal for applications where clearance is limited. With full threading extending to the pointed tip, these A/AB type screws ensure maximum thread contact throughout the entire material thickness, preventing loosening under vibration and thermal cycling common in metalworking applications. The combination of zinc plating and steel substrate offers reliable corrosion protection for both indoor and moderately corrosive environments.

Specification Summary & Compliance

This No. 7 x 3/8" tapping screw features a 0.151" thread diameter with 16 threads per inch in right-hand direction. The thread forming tapping method complies with standard A/AB screw specifications for sheet metal applications. Manufacturing follows precise dimensional tolerances with a pan head diameter of 0.296" and overall length of 3/8". The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for industrial use.
