S-97188A330 Length 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with 316 stainless steel construction, ideal for harsh industrial environments and outdoor applications
• Self-tapping efficiency through thread forming technology that creates strong, permanent threads without pre-threading requirements
• Optimized for sheet metal applications with precise No. 29 drill bit compatibility and 0.025" maximum drilling thickness capability
• Secure square drive engagement (No. 2 size) prevents cam-out and provides superior torque transmission during installation
• Full threading along 1-1/2" length ensures maximum grip strength and uniform stress distribution in assembled components
• Pan head design with rounded profile offers low-profile installation while providing adequate bearing surface
• Regulatory compliance assurance with RoHS 3 and REACH standards for environmentally responsible manufacturing

Professional Applications & Engineering Value

These 316 stainless steel tapping screws deliver exceptional performance in demanding sheet metal applications where corrosion resistance and structural integrity are paramount. The thread forming Type A/AB design creates precise, durable threads in base materials without chip formation, eliminating contamination risks in sensitive assemblies. With 15 threads per inch and right-hand threading, these fasteners provide reliable engagement in thin-gauge materials up to 0.025" thickness. The combination of square drive No. 2 and fully threaded shank ensures vibration resistance and consistent clamping force, making them ideal for HVAC systems, electrical enclosures, and industrial equipment where long-term reliability is critical in corrosive environments.

Specification Summary & Compliance

This No. 8 x 1-1/2" sheet metal tapping screw features inch system measurements with Class 2A thread tolerances and standard pan head configuration. Manufactured to Type A/AB thread forming standards with 0.164" thread diameter and pointed tip for optimal penetration. The product maintains full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global industrial applications requiring restricted substance control.
