S-92525A551 Length 3/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh environments and long-term outdoor applications
• Efficient thread forming action creates strong, permanent threads in sheet metal without chip removal, reducing assembly time
• Optimized Phillips pan head design provides excellent drive stability and a low-profile finish for flush mounting
• Precise No. 21 drill bit compatibility ensures perfect hole matching and eliminates material splitting during installation
• Full threading along the 3/8" length delivers maximum grip strength and uniform load distribution
• Environmental regulation compliance meets RoHS 3 and REACH standards for safe, sustainable industrial use
• Right-hand thread direction with 16 TPI offers reliable fastening performance in standard assembly operations

Professional Applications & Engineering Value

This Type B thread forming screw is engineered specifically for sheet metal applications where material integrity is critical. The 18-8 stainless steel composition provides exceptional resistance to rust and chemical exposure, making it suitable for HVAC systems, electronic enclosures, and automotive components. The thread forming technology eliminates the need for pre-tapped holes while creating stronger thread engagement through material displacement rather than cutting. This prevents loose fittings and reduces vibration-induced loosening in dynamic environments. The Phillips drive system with No. 2 size ensures secure tool engagement during high-torque installation, while the rounded pan head offers a finished appearance without sharp edges. These tapping screws deliver reliable performance in thin-gauge materials where strip-out resistance is paramount.

Specification Summary & Compliance

This precision fastener features a 0.19" thread diameter with 16 threads per inch and 3/8" length in fully threaded configuration. The screw maintains standard Class 2A thread tolerances for consistent fitment. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring restriction of hazardous substances. The Type B thread forming design follows industry-standard specifications for sheet metal fastening applications.
