S-90064A146 Length 3/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Efficient thread forming action creates stronger, more secure fastenings in steel and sheet metal without pre-drilling requirements
• Secure external hex drive with 1/4" head provides excellent torque transmission and prevents tool slippage during installation
• Integrated drilling tip with No. 2 point design penetrates up to 0.09" thickness, eliminating the need for pilot holes
• Flanged design distributes clamping force evenly, reducing surface damage and improving joint integrity
• Full threading along the 3/8" length ensures maximum engagement and pull-out resistance in thin materials
• Regulatory compliance with RoHS 3 and REACH standards guarantees environmental safety and global market acceptance

Professional Applications & Engineering Value

These No. 6 zinc-plated steel tapping screws deliver exceptional performance in steel and sheet metal applications where vibration resistance and joint reliability are critical. The thread forming design creates precise mating threads through material displacement rather than cutting, resulting in stronger connections with reduced risk of loosening under dynamic loads. The combination of external hex drive and flanged head provides superior installation control while preventing over-tightening in thin-gauge materials. The integrated drilling tip with 9/64" length streamlines assembly processes by eliminating secondary drilling operations, making these BSD tapping screws ideal for high-volume manufacturing environments requiring efficiency and consistent performance.

Specification Summary & Compliance

These thread forming tapping screws feature precise 0.138" thread diameter with 20 threads per inch and right-hand threading for standard industrial applications. The 3/8" fully threaded length and 1/4" hex head dimensions ensure consistent performance across production runs. Manufactured to BSD tapping screw standards with Class 2A thread fit for reliable engagement. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations confirms adherence to international safety standards for industrial components.
