S-90930A247 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with black-coated steel construction for extended service life in harsh environments
• Superior holding power through fully threaded design and thread forming method that creates strong, permanent threads in sheet metal
• Enhanced driving efficiency with No. 2 Phillips drive that reduces cam-out and improves installation speed
• Increased bearing surface from the flanged pan head design that distributes clamping force more effectively
• Quick starting and alignment thanks to the pointed tip that self-centers and initiates threading without pre-drilling
• Reliable performance in thin materials with maximum drilling thickness capability up to 0.025" for various sheet metal applications
• Industry compliance assurance meeting RoHS 3 and REACH environmental standards for global manufacturing requirements

Professional Applications & Engineering Value

This black corrosion-resistant coated steel tapping screw delivers exceptional value in sheet metal fabrication and assembly operations. The thread forming design eliminates the need for tapped holes, creating stronger threads that won't strip under vibration while reducing installation time and labor costs. The A/AB tapping screw type with fully threaded configuration ensures maximum engagement in thin materials, providing reliable fastening in HVAC systems, electrical enclosures, and automotive panels. The flanged pan head offers superior clamp load distribution, preventing material distortion while the No. 2 Phillips drive enables efficient installation with standard tools. This combination of features addresses critical industrial challenges including corrosion protection, vibration resistance, and assembly efficiency.

Specification Summary & Compliance

This No. 10-12 x 1" tapping screw features a 0.19" thread diameter with 12 threads per inch and Class 2A thread fit for reliable engagement. The screw meets A/AB tapping screw standards with thread forming method requiring No. 21 drill bit (0.159" diameter) for proper installation. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for industrial applications worldwide.
