S-90056A247 Length 1" 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 installation creates permanent, vibration-resistant threads in sheet metal without pre-tapping requirements
• Optimized Phillips No. 2 drive provides secure tool engagement and prevents cam-out during high-torque applications
• Complete thread engagement with fully threaded design ensures maximum holding power across the entire fastener length
• Precise blunt tip design enables accurate alignment and installation in pre-drilled No. 21 sized holes
• Robust pan head profile offers excellent bearing surface for secure fastening in sheet metal assemblies
• Environmental compliance assurance with RoHS 3 certification for sustainable manufacturing practices

Professional Applications & Engineering Value

These zinc-plated steel tapping screws deliver exceptional performance in sheet metal applications where reliability and installation efficiency are critical. The thread forming Type B design eliminates the need for pre-tapped holes, reducing assembly time and labor costs while creating strong, permanent threads that resist loosening under vibration. The Phillips pan head configuration provides optimal driving torque transfer and a low-profile finish that sits flush against metal surfaces. Engineered with a blunt tip and precise 0.19" thread diameter, these screws ensure accurate alignment in pre-drilled holes, preventing material damage and ensuring consistent clamping force. The combination of 16 threads per inch and fully threaded shank maximizes pull-out resistance, making them ideal for HVAC systems, electrical enclosures, automotive panels, and industrial equipment where sheet metal fastening integrity is paramount.

Specification Summary & Compliance

This No. 10-16 x 1" tapping screw features precision right-hand threads with standard thread forming tolerances suitable for sheet metal applications. Manufactured from zinc-plated steel with a pan head profile and Phillips No. 2 drive, the fastener is engineered for use with No. 21 drill bit (0.159" diameter) prepared holes. The product maintains dimensional accuracy throughout its 1" fully threaded length and complies with RoHS 3 (2015/863/EU) environmental regulations, ensuring adherence to international substance restriction standards for industrial components.
