S-97188A305 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh industrial environments and outdoor applications.
• Efficient thread forming design creates strong, permanent threads in sheet metal without pre-drilling, saving time and labor costs.
• High-torque square drive (No. 2) ensures secure bit engagement and reduces cam-out for reliable, repeatable installations.
• Fully threaded shank provides maximum grip and uniform clamping force across the entire 1/2" length in materials up to 0.025" thick.
• Standard pan head profile offers a low-profile finish with good bearing surface for stable fastening in sheet metal assemblies.
• Environmental compliance meets RoHS 3 and REACH standards, ensuring safe use in regulated industries and global markets.
• Precision No. 8-15 thread delivers excellent pull-out resistance and vibration resistance in thin-gauge metal applications.

Professional Applications & Engineering Value

Engineered for demanding sheet metal applications, these thread forming screws eliminate the need for separate tapping operations, significantly reducing assembly time and tooling requirements. The 316 stainless steel composition provides exceptional resistance to chlorides and acidic environments, making these A/AB type tapping screws ideal for HVAC systems, electronic enclosures, and marine components. The fully threaded No. 8-15 design with pointed tip ensures easy starting and consistent thread engagement in materials up to 0.025" thickness, while the square drive prevents stripping during high-torque installations. This combination of corrosion-resistant material and efficient thread forming technology delivers reliable performance in thin-section metals where vibration loosening and environmental degradation are common concerns.

Specification Summary & Compliance

This No. 8-15 x 1/2" tapping screw features precision right-hand threads with approximately 15 threads per inch and a thread diameter of 0.164". Manufactured to industry standards for thread forming screws with A/AB type designation, it requires a No. 29 drill bit (0.136" diameter) for optimal performance. The screw complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring restriction of hazardous substances for industrial safety and sustainability requirements.
