S-93945A035 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 Stainless Steel construction, ideal for harsh industrial environments and long-term reliability.
• Efficient thread forming design creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time and tooling needs.
• Secure, cam-out resistant drive with a No. 2 Square Drive, ensuring high torque transfer and minimizing screw head damage during installation.
• Flush, low-profile seating provided by the standard 82° Flat Head, allowing for a smooth surface finish in assembled sheet metal components.
• Full threading along the 1" length ensures maximum grip and uniform stress distribution across the entire fastened joint.
• Precision compatibility with a No. 21 drill bit (0.159" diameter), facilitating accurate pilot holes for optimal thread engagement in materials up to 0.025" thick.
• Compliance with RoHS 3 and REACH regulations guarantees environmentally safe and legally acceptable fasteners for global industrial supply chains.

Professional Applications & Engineering Value

These No. 10-12 thread forming tapping screws are specifically engineered to address common challenges in sheet metal assembly, such as material fatigue and corrosion. The 18-8 Stainless Steel composition provides excellent strength and resistance to oxidation, making them suitable for outdoor, marine, or chemically exposed environments. The thread forming (A/AB type) design displaces material rather than cutting it, which results in higher thread strength and reduced risk of loosening under vibration—critical for automotive, HVAC, and electronic enclosure applications. The combination of a flat head with an 82° countersink and square drive ensures a secure, flush fit that maintains structural integrity and aesthetic requirements in finished products.

Specification Summary & Compliance

This fastener adheres to standard inch measurements with a No. 10 screw size, 12 threads per inch, and a 1" length, fully threaded for consistent performance. The flat head profile conforms to industry standards with an 82° countersink angle. It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring the absence of hazardous substances and supporting sustainable industrial practices.
