S-97188A310 Length 5/8" 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 action creates strong, permanent threads in sheet metal, eliminating the need for pre-tapped holes and speeding up assembly.
• High-strength, fully threaded design ensures maximum grip and load distribution along the entire shank for a more secure and reliable fastening.
• Easy installation and removal with a square drive (No. 2) and pan head, providing a positive grip that resists cam-out and reduces tool slippage.
• Optimized for sheet metal with a pointed tip and specified No. 29 drill bit size, ensuring clean starts and precise alignment for faster, more accurate installations.
• Reliable performance with a right-hand thread and 15 threads per inch, delivering consistent clamping force and vibration resistance in demanding applications.
• Compliance with global environmental standards including RoHS 3 and REACH, ensuring safety and regulatory acceptance for international supply chains.

Professional Applications & Engineering Value

These No. 8 tapping screws are precision-engineered from 316 stainless steel to solve common challenges in sheet metal assembly. The thread forming technology displaces material to create robust internal threads without generating chips, which prevents contamination in sensitive equipment and reduces the risk of loose metal shavings causing electrical shorts. This is critical in enclosures, HVAC systems, and automotive panels. The fully threaded and pointed tip design ensures quick starts and full engagement, even in thin-gauge materials up to 0.025" thick, minimizing the time and labor required for high-volume production lines. The A/AB tapping screw type and pan head with square drive offer a reliable, high-torque solution that withstands vibration, making these screws a durable choice for machinery, electronic chassis, and structural frameworks where long-term integrity is non-negotiable.

Specification Summary & Compliance

This screw is a No. 8 size with a 5/8" length and features a Class 2A thread fit for standard industrial applications. The thread diameter is 0.164" with 15 threads per inch, conforming to common tapping screw standards. It is designed for use with a No. 29 drill bit (0.136" diameter) for optimal performance in sheet metal. The product is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances and suitable for global markets.
