S-96231A420 Length 5/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Efficient thread forming design creates strong, permanent threads in sheet metal without requiring pre-tapped holes
• Optimal flush installation with 82° countersink angle and flat head profile for smooth, professional finishes
• Enhanced driving control through Phillips No. 1 drive system, reducing cam-out and tool slippage
• Maximum holding power from fully threaded design that distributes load evenly across the entire fastener length
• Quick material identification with distinctive brass-colored finish for easy inventory management
• Precision compatibility with No. 44 drill bits (0.086" diameter) for accurate hole preparation in sheet metal up to 0.025" thickness

Professional Applications & Engineering Value

These No. 4-24 thread forming screws are engineered specifically for sheet metal applications where reliable fastening is critical. The zinc-plated steel construction provides essential corrosion protection while maintaining the strength needed for industrial environments. The A/AB tapping screw type with thread forming design eliminates the need for separate tapping operations, significantly reducing installation time and labor costs. The fully threaded configuration ensures maximum engagement in thin materials, preventing loosening from vibration - a common challenge in sheet metal assemblies. The Phillips flat head design with standard profile allows for flush mounting, creating clean, professional appearances in visible applications while the pointed tip facilitates precise starting alignment.

Specification Summary & Compliance

This No. 4-24 x 5/8" tapping screw features a 0.112" thread diameter with approximately 24 threads per inch in right-hand direction, conforming to standard thread forming specifications for sheet metal applications. The fastener maintains precise dimensional accuracy with Class 2A thread tolerances and is manufactured to meet industrial tapping screw standards. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental responsibility and workplace safety, making these screws suitable for regulated industries and international supply chains.
