S-92525A557 Length 3/4" 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 with Type B design creates strong, permanent threads in sheet metal without pre-tapping, reducing assembly time.
• Optimized torque transfer via Phillips No. 2 drive, minimizing cam-out and enhancing installation precision.
• Full 3/4" threading provides maximum grip length for secure fastening in sheet metal applications.
• Standard pan head profile offers a low-profile, rounded finish that resists snagging and improves safety.
• Precise compatibility with No. 21 drill bits (0.159" diameter) ensures proper hole sizing and reduces material stress.
• Environmental compliance with RoHS 3 and REACH standards, meeting global regulatory requirements for hazardous substances.

Professional Applications & Engineering Value

This No. 10-16 thread forming screw is engineered to address common challenges in sheet metal fabrication, such as strip-out and material fatigue. The 18-8 stainless steel composition provides excellent resistance to oxidation and chemical exposure, making it ideal for outdoor equipment, electrical enclosures, and HVAC systems. Its Type B thread forming action displaces material rather than cutting it, resulting in zero chip generation and stronger thread engagement that withstands vibration. The Phillips pan head design allows for flush mounting and easy driver access, while the 0.19" thread diameter and 16 TPI ensure a tight fit in pre-drilled holes. These features collectively reduce installation errors, lower maintenance costs, and extend service life in demanding industrial fastening scenarios.
