S-91515A300 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Enhanced fastening stability through wide truss head design with 0.44" flange diameter, distributing load evenly across surfaces
• Efficient installation with Phillips No. 2 drive system providing reliable torque transfer and reduced cam-out risk
• Self-tapping capability using thread forming technology that creates strong, permanent threads without pre-drilling in steel and sheet metal
• Maximum material penetration with 3/16" drill tip length and 0.098" maximum drilling thickness for versatile application range
• Complete thread engagement through fully threaded design ensuring superior holding power across the entire screw length
• Regulatory compliance meeting RoHS 3 standards for environmentally responsible manufacturing and global market acceptance

Professional Applications & Engineering Value

These No. 8 zinc-plated steel tapping screws deliver exceptional performance in steel and sheet metal applications where vibration resistance and permanent fastening are critical. The thread forming technology eliminates the need for separate tapping operations, reducing installation time and labor costs while creating stronger thread engagement than cutting alternatives. The wide truss head with integrated flange provides superior clamping force distribution, preventing material distortion in thin-gauge applications. With their fully threaded design and specialized drilling tip, these BSD tapping screws maintain consistent performance across varying material thicknesses up to 0.098", making them ideal for HVAC systems, electrical enclosures, and metal fabrication projects where reliability cannot be compromised.

Specification Summary & Compliance

This No. 8 x 1" flanged tapping screw features precise 0.164" thread diameter with 18 TPI right-hand threads following BSD standards for consistent performance. Manufactured from zinc-plated steel with Phillips No. 2 drive and fully threaded construction, these screws maintain dimensional accuracy for reliable installation. The product is RoHS 3 (2015/863/EU) Compliant, ensuring adherence to international environmental regulations while delivering the mechanical properties required for industrial fastening applications in steel and sheet metal substrates.
