Professional Applications & Engineering Value
This No. 4-24 x 1/4" zinc-plated steel tapping screw is engineered to address common challenges in sheet metal assembly, such as material fatigue and thread stripping. Its thread forming technology creates precise, strong threads in pre-drilled holes without generating chips, reducing contamination and improving joint integrity. The fully threaded shank and pointed tip facilitate easy starts and consistent engagement, while the Phillips/Slotted drive offers flexibility for various tool types. Ideal for HVAC, electronics enclosures, and automotive panels, this A/AB type tapping screw ensures reliable fastening in thin-gauge materials up to 0.025" thickness, enhancing structural stability and assembly speed.
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 No. 44 drill bit (0.086" diameter) prepped holes. The Class 2A thread tolerance and right-hand threading provide consistent performance in sheet metal applications. Manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, it is free of restricted substances, supporting environmentally responsible manufacturing practices.
