S-90056A110 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments
• Efficient thread forming action creates strong, permanent threads in sheet metal without requiring pre-tapped holes
• Optimized Phillips drive design provides secure tool engagement and reduces cam-out during installation
• Full threading along entire shank length ensures maximum grip strength and uniform load distribution
• Precise No. 44 drill bit compatibility enables accurate hole preparation and consistent installation results
• Right-hand thread direction follows industry standards for intuitive installation and removal operations
• RoHS 3 compliance meets international environmental regulations for safe use in global manufacturing

Professional Applications & Engineering Value

These zinc-plated steel tapping screws deliver exceptional performance in sheet metal applications where traditional fastening methods fall short. The thread forming Type B design eliminates the need for separate tapping operations by cold-forming precise internal threads directly into parent material, creating stronger thread engagement than cutting alternatives. The Phillips pan head configuration provides a low-profile finish while maintaining excellent drive torque transmission. Engineered with full threading and 0.112" thread diameter, these screws distribute clamping forces evenly across the entire fastened joint, preventing material distortion in thin-gauge metals. The combination of zinc plating corrosion protection and right-hand threading makes these industrial fasteners ideal for assembly lines requiring consistent, reliable performance in HVAC systems, electronic enclosures, and automotive components.

Specification Summary & Compliance

This No. 4-24 x 1/2" tapping screw features inch system measurements with standard Class 2A thread tolerances for consistent fit. The thread forming Type B design follows industry-standard geometry for creating strong, permanent threads in ductile materials. Manufacturing complies with RoHS 3 (2015/863/EU) regulations, ensuring environmental compliance for international markets. The screw is engineered for use with standard No. 44 drill bits (0.086" diameter) and features a blunt tip optimized for thread forming applications in sheet metal up to the specified 1/2" engagement length.
