S-90064A631 Length 1 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding environments
• Eliminates pre-tapping operations through thread forming design, reducing installation time and labor costs
• Enhanced drilling capability with No. 3 drill tip penetrating up to 0.21" thickness in steel and sheet metal
• Secure flange design provides wider bearing surface for improved load distribution and vibration resistance
• External hex drive enables high-torque installation with standard tools for reliable fastening
• Fully threaded shank ensures maximum grip length and uniform stress distribution along the entire fastener
• BSD thread forming technology creates strong, precise threads without chip removal in base materials

Professional Applications & Engineering Value

These zinc-plated steel tapping screws deliver exceptional performance in steel and sheet metal applications where durability and installation efficiency are critical. The thread forming design creates permanent, high-strength threads by displacing material rather than cutting it, eliminating loose chips that could compromise electrical systems or moving parts. The integrated No. 3 drilling tip combined with the external hex drive allows for single-operation installation, significantly reducing assembly time in production environments. The flanged hex head provides excellent clamp load distribution while the zinc plating offers reliable protection against corrosion in industrial settings. These BSD tapping screws are engineered to maintain joint integrity under vibration and dynamic loads common in machinery, enclosures, and structural assemblies.

Specification Summary & Compliance

These 1/4"-14 thread forming screws feature precision right-hand threads with industry-standard dimensions including 3/8" hex head width and 1 3/4" overall length. The thread forming tapping method complies with BSD standards for reliable performance in various steel and sheet metal thicknesses. Manufactured to exacting tolerances, these fully threaded screws ensure consistent engagement and clamping force. The zinc plating provides corrosion resistance while meeting industry requirements for fastener performance in industrial applications.
