S-92470A194 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-term reliability in harsh industrial environments.
• Efficient thread forming design creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time and tooling costs.
• Optimized Phillips drive system (No. 2 size) provides secure torque transmission and prevents cam-out during high-speed assembly operations.
• Precision 15 TPI thread pitch delivers excellent holding power and vibration resistance in thin sheet metal applications up to 0.025" thickness.
• Standard pan head profile offers a balanced combination of low-profile appearance and sufficient bearing surface for secure fastening.
• Full threading and pointed tip enable quick starting and smooth penetration into pre-drilled holes (No. 29 drill bit recommended).
• Comprehensive regulatory compliance with RoHS 3 and REACH standards ensures environmental safety and global market acceptance.

Professional Applications & Engineering Value

These 18-8 stainless steel tapping screws are engineered specifically for sheet metal applications where corrosion resistance and structural integrity are paramount. The thread forming technology (A/AB type) eliminates the need for separate tapping operations by cold-forming mating threads directly into the base material, creating superior pull-out strength and vibration resistance. The Phillips drive system combined with the pan head design provides reliable installation in confined spaces while maintaining a professional finish. Ideal for HVAC systems, electronic enclosures, and automotive components, these screws deliver consistent performance in thicknesses up to 0.025" when used with the recommended No. 29 drill bit (0.136" diameter), making them essential for precision metal fastening applications requiring durable, compliant fasteners.

Specification Summary & Compliance

This No. 8 x 1/2" tapping screw features a 0.164" thread diameter with 15 TPI precision threading and right-hand thread direction.
