S-90048A111 Length 5/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-lasting performance in demanding industrial environments.
• Efficient thread forming design creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time and tooling costs.
• Secure fastening with standard 82° countersink allows the flat head to sit flush with surfaces, providing a clean finish and preventing snagging.
• Reliable drive engagement via Phillips No. 1 drive style offers controlled torque application and reduces cam-out risks during installation.
• Full threading along the 5/8" length ensures maximum grip and uniform stress distribution in sheet metal assemblies.
• Compliance with RoHS 3 and REACH regulations guarantees safe, environmentally responsible use in global industrial supply chains.
• Optimized for No. 44 drill bit (0.086" diameter) simplifies hole preparation and enhances alignment accuracy in sheet metal up to 0.025" thickness.

Professional Applications & Engineering Value

Engineered for sheet metal applications, these No. 4-24 thread forming tapping screws address common industrial challenges such as material fatigue and assembly inefficiency. The zinc-plated steel construction provides a durable barrier against rust and chemical exposure, extending service life in HVAC, electronics enclosures, and automotive panels. The A/AB tapping screw type with a pointed tip and right-hand threading displaces material to form precise, high-strength threads without chips, eliminating the need for separate tapping operations and reducing labor costs. This fully threaded design ensures consistent clamping force, preventing loosening under vibration—a critical advantage in machinery and structural frameworks where reliability is paramount.

Specification Summary & Compliance

This screw adheres to standard inch measurements with a thread diameter of 0.112" and 24 threads per inch, ensuring precise fit in pre-drilled holes. It features a flat head with standard profile and Class 2A thread tolerances for reliable engagement. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), confirming the absence of restricted hazardous substances, making it suitable for regulated industrial and export markets.
