S-90053A110 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-lasting performance in demanding industrial environments.
• Effortless installation through thread forming technology that creates strong, permanent threads without pre-tapping in sheet metal.
• Wide compatibility with No. 44 drill bits (0.086" diameter) for materials up to 0.025" thickness, streamlining your assembly process.
• Reliable torque transmission with the slotted pan head design, providing secure fastening and easy driver engagement.
• Full-length threading ensures maximum grip and uniform load distribution across the entire fastener length.
• Compliance with environmental standards including RoHS 3 and REACH, making them safe for global industrial applications.
• Precision-engineered dimensions with 0.112" thread diameter and 24 TPI for consistent performance in sheet metal assemblies.

Professional Applications & Engineering Value

These No. 4-24 x 1/2" zinc-plated steel tapping screws are engineered specifically for sheet metal applications, where traditional fasteners may strip or loosen under vibration. The thread forming design displaces material to create strong, clean threads without chips, eliminating the need for secondary operations. Made from zinc-plated steel, they resist corrosion in humid or outdoor environments, while the slotted pan head allows for quick installation with standard tools. Ideal for HVAC systems, electronic enclosures, and automotive panels, these fully threaded screws provide uniform clamping force, reducing the risk of joint failure in thin-gauge materials up to 0.025" thickness.

Specification Summary & Compliance

This thread forming tapping screw adheres to standard inch measurements with a No. 4 screw size, 0.112" thread diameter, and 24 threads per inch. It features a slotted pan head with 0.219" diameter and 0.069" height, designed for right-hand threading and fully threaded engagement. Manufactured to precise tolerances for consistent performance, it complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and suitability for industrial use in sheet metal assemblies.
