• Maximum material engagement through fully threaded design ensures superior holding power and vibration resistance in sheet metal applications
• Streamlined installation process with blunt tip and standard pan head profile for easy alignment and consistent seating
• Precision thread compatibility with 18 TPI and 0.164" diameter ensures perfect fit and reliable performance in standard sheet metal thicknesses
• Environmental compliance assurance with RoHS 3 certification for use in regulated industries and global supply chains

Professional Applications & Engineering Value

These Type B thread forming screws are engineered specifically for sheet metal fastening applications where reliability and installation efficiency are critical. The zinc-plated steel construction provides essential corrosion protection for industrial environments, while the thread forming technology eliminates the need for separate tapping operations, significantly reducing assembly time and costs. The Phillips No. 2 drive system ensures consistent torque application without cam-out, making them ideal for high-volume production environments. With full threading and precise 18 TPI configuration, these screws deliver maximum pull-out resistance and vibration durability in sheet metal assemblies, electrical enclosures, HVAC systems, and automotive components where secure fastening is non-negotiable.

Specification Summary & Compliance

This No. 8 x 1/4" tapping screw features standard inch measurements with 0.164" thread diameter and 18 threads per inch precision threading. The screw complies with industry-standard thread forming specifications for Type B applications and is designed for use with No. 29 drill bits (0.136" diameter). Manufacturing and material compliance includes RoHS 3 (2015/863/EU) certification, ensuring environmental regulatory adherence for industrial and commercial applications worldwide. The right-hand thread direction and fully threaded shank provide consistent performance across all standard sheet metal thicknesses.
