S-94061A217 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Self-drilling capability with integrated drill tip eliminates pre-drilling requirements, reducing installation time and labor costs
• Strong thread formation through thread forming technology creates secure, vibration-resistant fastenings in steel and sheet metal
• Enhanced driving efficiency with Phillips No. 2 drive provides reliable torque transfer and reduces cam-out incidents
• Flush finishing with standard oval head profile and 82° countersink angle for smooth, professional-looking installations
• Full-thread engagement along the entire 1/2" length ensures maximum holding power and load distribution
• Regulatory compliance meets RoHS 3 and REACH standards for safe, environmentally responsible manufacturing

Professional Applications & Engineering Value

These No. 8 zinc-plated steel tapping screws deliver exceptional performance in steel and sheet metal applications where reliability is critical. The thread forming technology creates precise mating threads without generating chips, preventing contamination in sensitive assemblies. The integrated drilling tip penetrates up to 0.1" thickness, eliminating secondary drilling operations and reducing installation time by up to 50%. The fully threaded design ensures maximum contact surface area, providing superior pull-out resistance and vibration damping in dynamic load conditions. The zinc plating offers reliable corrosion protection, while the oval head with Phillips drive combines aesthetic appeal with practical installation efficiency for HVAC, electrical enclosures, and metal fabrication projects.

Specification Summary & Compliance

These BSD tapping screws feature precision 0.164" thread diameter with 18 threads per inch in right-hand orientation. The standard oval head profile measures 0.312" diameter with 0.152" height, designed for 82° countersink applications. Manufactured to industry standards for thread forming screws with Class 2A thread tolerances. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across industrial sectors.
