S-90203A112 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Eliminates pre-drilling requirements with an integrated drilling tip that penetrates up to 0.15" thickness in aluminum and sheet metal, saving significant labor time and tooling costs.
• Superior corrosion resistance provided by 18-8 Stainless Steel material, ensuring long-term reliability and performance in demanding industrial environments.
• High-strength thread forming design creates strong, durable threads in the base material for a secure, vibration-resistant fastening solution.
• Efficient square drive (No. 2) offers excellent torque transmission, reducing cam-out and driver slippage for faster, more reliable installation.
• Fully threaded shank maximizes grip and holding power along the entire 1" length, providing a consistent and robust connection.
• Standard pan head with rounded profile offers a low-profile finish and a larger bearing surface for secure fastening.
• Compliant with major environmental regulations including RoHS 3 and REACH, ensuring they are safe for use in regulated industries and global supply chains.

Professional Applications & Engineering Value

These No. 10 self-drilling screws are precision-engineered to solve critical fastening challenges in aluminum and sheet metal fabrication. The 18-8 stainless steel construction provides the necessary strength and corrosion resistance for HVAC, electrical enclosures, and metal framing applications. The thread forming (tapping) method displaces material to create a zero-clearance fit, which results in higher pull-out strength and resistance to loosening under vibration compared to thread-cutting alternatives. The integrated drilling tip (Type No. 3) consistently penetrates the specified material thickness, eliminating the time-consuming and often misaligned pre-drilling step. This combination of a durable material and an efficient self-drilling design directly translates into reduced assembly time, lower installed cost, and a more reliable final product for engineers and contractors.

Specification Summary & Compliance

This fastener is a No. 10-16 x 1" screw with a 0.19" thread diameter and approximately 16 threads per inch (TPI). It features a right-hand thread direction and is fully threaded. The head is a pan style with a 0.373" diameter and is driven by a No. 2 square drive. This product is manufactured to be RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting stringent international standards for restricted substances.
