S-90064A148 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Eliminates pre-drilling requirements with integrated drilling tip that penetrates up to 0.09" thickness in steel and sheet metal
• Superior corrosion resistance provided by zinc-plated steel construction for extended service life in industrial environments
• High-torque installation capability through external hex drive design that prevents tool slippage during fastening
• Maximum thread engagement with fully threaded shank that ensures consistent holding power across the entire fastener length
• Enhanced load distribution from integrated flange design that reduces surface pressure and prevents material deformation
• Reliable thread formation through BSD thread forming technology that creates strong, vibration-resistant connections
• Environmental compliance assurance with RoHS 3 certification for safe use in regulated applications

Professional Applications & Engineering Value

These No. 6 zinc-plated steel tapping screws deliver exceptional value in steel and sheet metal fabrication by combining drilling and fastening operations into a single step. The thread forming design creates precise mating threads without generating chips, eliminating contamination risks in sensitive assemblies. The external hex drive provides superior torque transmission compared to Phillips heads, reducing installation time while preventing cam-out failures. With fully threaded shanks maintaining consistent engagement and flanged heads distributing clamp load effectively, these screws solve common challenges of material deformation and vibration loosening in thin-section metal applications. The drilling tip geometry specifically engineered for 0.09" maximum thickness ensures reliable penetration in standard gauge materials without pilot holes.

Specification Summary & Compliance

These thread forming tapping screws feature a No. 6 size with 0.138" thread diameter and 20 threads per inch in right-hand orientation. The 1/4" hex head provides standard wrench compatibility while the 1/2" length offers versatile fastening depth. Manufactured to BSD tapping screw standards with fully threaded round shank configuration and No. 2 drill tip type. Compliant with RoHS 3 (2015/863/EU) environmental regulations for restricted substance control, ensuring suitability for global manufacturing requirements.
