S-90064A734 Length 3" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-lasting performance in harsh industrial environments.
• Effortless installation through thread forming technology that creates strong, permanent threads without pre-tapping, saving time and labor costs.
• Maximum penetration capability with a drilling tip designed to pierce up to 0.098" thickness in steel and sheet metal, eliminating the need for pilot holes.
• Secure, non-slip fastening thanks to the external hex drive and 1/4" hex head, providing high torque application and reducing tool slippage.
• Enhanced load distribution from the integrated flange, which increases clamping force and prevents loosening under vibration.
• Full-length threading ensures consistent grip along the entire 3" length, offering reliable holding power in varied material thicknesses.
• Broad compatibility with standard No. 8 BSD tapping screw applications, making it a versatile choice for multiple industrial fastening needs.

Professional Applications & Engineering Value

These No. 8 zinc-plated steel tapping screws are engineered to address common challenges in steel and sheet metal assemblies, where speed, durability, and reliability are critical. The thread forming design eliminates the risk of cross-threading and reduces assembly time by forming precise, strong threads directly into the material, enhancing joint integrity. With a drilling tip and fully threaded shank, they provide quick penetration and consistent grip, ideal for HVAC, automotive, and machinery applications. The external hex drive and flange ensure secure installation under high torque, minimizing the need for additional washers and reducing maintenance in demanding industrial environments.
