S-90077A316 Length 1 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-lasting performance in industrial environments
• Enhanced torque transmission and versatility through the combined Phillips/Slotted drive design, reducing tool slippage and installation time
• Strong, permanent thread formation in sheet metal without pre-tapping, minimizing assembly steps and improving joint integrity
• Optimal grip and uniform pressure distribution from the standard pan head profile, preventing surface damage and loosening under vibration
• Full-length threading for maximum holding power across the entire 1-1/4" length, providing reliable fastening in various material thicknesses
• Precision 10 TPI threading and 0.242" diameter ensures consistent engagement and reduces the risk of strip-out in sheet metal applications
• Compliance with RoHS 3 and REACH standards guarantees safe, environmentally responsible use in regulated industries

Professional Applications & Engineering Value

This No. 14 zinc-plated steel tapping screw is engineered to address common challenges in sheet metal fabrication, such as thread stripping and corrosion-induced failure. The thread forming (Type A/AB) design displaces material to create robust, burr-free internal threads, eliminating the need for separate tapping operations and reducing assembly costs. With a Phillips/Slotted drive, it accommodates various tools, enhancing workflow flexibility in HVAC, automotive, and electronics enclosures. The fully threaded shank and pointed tip facilitate easy starting and consistent clamping force, making it ideal for joining thin-gauge metals where vibration resistance and durability are critical.

Specification Summary & Compliance

This screw features a 0.242" thread diameter with 10 TPI precision threading (Class 2A equivalent) and a 1-1/4" length for accurate fit. It conforms to thread forming standards for Type A/AB tapping screws and is designed for use with a 5.5 mm (0.2165") drill bit in materials up to 0.025" thickness. The product is RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, meeting stringent industrial safety and environmental regulations.
