S-90090A203 Length 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction for extended service life in demanding industrial environments
• Efficient thread forming design creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time
• Optimized pan head design provides excellent drive stability and prevents over-tightening in sheet metal applications
• Full threading with pointed tip ensures quick starting and smooth penetration through sheet metal substrates
• Right-hand threading with 15 TPI delivers reliable fastening performance in standard sheet metal thicknesses
• Environmental compliance assurance meets RoHS 3 and REACH regulations for safe use in regulated industries
• Precision sizing compatibility with No. 29 drill bit (0.136") for perfect fit in 0.025" maximum thickness sheet metal

Professional Applications & Engineering Value

These thread forming sheet metal screws provide exceptional engineering value for metal fabrication and assembly operations. The 18-8 stainless steel composition offers excellent resistance to corrosion and oxidation, making them ideal for applications where environmental exposure is a concern. The A/AB tapping screw type with thread forming capability eliminates the need for separate tapping operations, creating strong, load-bearing threads directly in the parent material. This design significantly reduces assembly time while providing vibration-resistant fastening in sheet metal applications. The pan head configuration ensures sufficient bearing surface for secure fastening without sinking into thinner gauge metals, while the fully threaded design maintains consistent clamping force across the entire engagement length.

Specification Summary & Compliance

This No. 8-15 x 1-1/2" sheet metal tapping screw features precision thread forming design with standard Class 2A thread tolerances. The fastener maintains 0.164" thread diameter with 15 threads per inch and right-hand threading conforming to standard industrial specifications. Manufacturing and material compliance includes full adherence to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial sectors. The screw is engineered for use with No. 29 drill bits (0.136" diameter) in sheet metal up to 0.025" maximum thickness.
