S-90286A246 Length 7/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior thread-forming capability creates permanent, vibration-resistant threads in sheet metal without pre-tapping, reducing installation time and tooling costs.
• Robust hex/slotted head design provides versatile driving options with a standard 0.313" head width for high-torque application and easy removal.
• Integrated flange with a 0.414" diameter distributes clamping force evenly, preventing pull-through and ensuring a secure, flush fit.
• Precision-engineered pointed tip and full threading ensure fast, straight starts and maximum thread engagement along the entire 7/8" length.
• Optimized for 0.025" maximum material thickness when used with a No. 21 drill bit (0.159" diameter), delivering reliable performance in standard sheet metal gauges.
• Compliance with RoHS 3 and REACH regulations guarantees the screw is free of hazardous substances, making it safe for use in regulated industries and export markets.
• Right-hand, fully threaded design ensures consistent, high-strength fastening in high-vibration environments common in metal assemblies.

Professional Applications & Engineering Value

This No. 10-12 hex head tapping screw is specifically engineered for sheet metal applications where reliability and speed are critical. The Type A thread-forming design displaces material to form strong, clean internal threads, eliminating the need for separate tapping operations and reducing the risk of cross-threading. The combination of an external hex/slotted drive and integrated flange provides exceptional grip and seating, preventing cam-out and distributing load to minimize sheet distortion. Made for use with a standard No. 21 drill bit, it streamlines assembly in HVAC, electrical enclosures, and machinery panels, ensuring durable, long-lasting joints even under dynamic loads.

Specification Summary & Compliance

This screw conforms to standard inch measurements with a thread diameter of 0.19" and 12 threads per inch. It is fully threaded with a pointed tip for easy insertion. The product is manufactured to be RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring adherence to strict environmental and safety standards for industrial components.
