S-90356A215 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction and black oxide coating for extended service life in harsh industrial environments
• Efficient thread forming technology creates strong, permanent threads in sheet metal without chip removal, reducing installation time and improving joint integrity
• Optimized for sheet metal applications with precise No. 32 drill bit compatibility (0.116" diameter) for maximum 0.025" drilling thickness
• Reliable Phillips drive system (No. 2 size) provides secure torque transmission and prevents cam-out during installation
• Full threading and pointed tip ensure easy starting and consistent engagement throughout the material thickness
• Pan head design offers low-profile fastening with good bearing surface for secure sheet metal connections
• Comprehensive regulatory compliance meets RoHS 3 and REACH standards for global industrial applications

Professional Applications & Engineering Value

These black oxide 18-8 stainless steel tapping screws deliver exceptional performance in demanding sheet metal applications where corrosion resistance and joint reliability are critical. The thread forming technology (A/AB type) eliminates the need for tapping operations by cold-forming mating threads directly into the material, creating stronger connections than conventional cutting screws. This prevents metal chip accumulation in sensitive assemblies while maintaining 0.138" diameter precision with 18 TPI thread spacing. The combination of Phillips drive and pan head design ensures consistent installation torque and reliable clamping force distribution across 1/2" length engagement. Ideal for HVAC systems, electronic enclosures, and automotive components where vibration resistance and environmental durability are essential.

Specification Summary & Compliance

These thread forming tapping screws feature precise 0.138" diameter with 18 threads per inch in right-hand direction, fully threaded construction, and standard Class 2A thread fit for reliable engagement. Manufacturing complies with A/AB tapping screw standards for consistent performance in sheet metal applications. The products are fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting international environmental and safety regulations for industrial fastener applications.
