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 labor costs.
- Dual-drive compatibility with Phillips and slotted heads offers flexibility for various assembly tools and operator preferences.
- Full threading along the 5/8" length provides maximum grip and uniform load distribution in sheet metal applications.
- Optimized for 0.025" maximum drilling thickness with precise No. 44 drill bit compatibility, ensuring clean installations and material integrity.
- Pan head design delivers a low-profile, finished appearance while preventing surface damage during tightening.
- Compliance with RoHS 3 and REACH regulations guarantees safe, environmentally responsible use in global supply chains.
Professional Applications & Engineering Value
This No. 4-24 x 5/8" zinc-plated steel tapping screw is engineered to address common challenges in sheet metal fabrication, such as material splitting and loose fasteners. Its thread-forming A/AB type design displaces metal to create robust, vibration-resistant threads without chips, ideal for HVAC systems, electrical enclosures, and automotive panels. The fully threaded shaft ensures consistent clamping force, while the Phillips/slotted drive accommodates both manual and automated assembly. With a 0.112" thread diameter and 24 threads per inch, it delivers precise engagement for secure, long-term fastening in thin-gauge materials.
Specification Summary & Compliance
This screw adheres to Class 2A inch-series tolerances with a right-hand thread direction and fully threaded profile. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance standards, ensuring no restricted substances are used. Designed for use with a No. 44 drill bit (0.086" diameter), it supports a maximum drilling thickness of 0.025" in sheet metal applications.
