• Optimized thread design with 24 threads per inch ensures secure fastening and reliable performance in thin sheet metal applications.

Professional Applications & Engineering Value

These zinc-plated steel tapping screws are engineered specifically for sheet metal applications where traditional fastening methods fall short. The thread forming design eliminates the need for pre-tapped holes, creating strong internal threads that resist vibration loosening and material fatigue. The Phillips drive system with No. 1 size provides excellent torque transmission while the pan head profile offers a low-profile finish ideal for confined spaces. The pointed tip ensures precise starting alignment, reducing installation time and preventing material damage. These screws are particularly valuable in sheet metal fabrication, HVAC systems, electrical enclosures, and automotive assemblies where reliable fastening in thin materials is critical for structural integrity and long-term performance.

Specification Summary & Compliance

This No. 4-24 x 1" tapping screw features a 0.112" thread diameter with 24 threads per inch in right-hand orientation, fully threaded design, and standard Class 2A thread tolerances. Manufactured to industry standards for thread forming sheet metal screws, it requires a No. 44 drill bit (0.086" diameter) for proper installation. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory adherence for industrial applications worldwide.
