S-90286A247 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Superior torque transmission with external hex/slotted drive for reliable installation and removal in demanding industrial environments
• Excellent material displacement through thread forming design creates strong, permanent threads in sheet metal without chips
• Enhanced load distribution with integrated flange design that eliminates the need for separate washers and prevents surface damage
• Quick and precise alignment with pointed tip that facilitates accurate screw placement and faster assembly operations
• Full-length threading provides maximum grip along the entire 1" length for superior holding power in sheet metal applications
• Environmental compliance assurance with RoHS 3 and REACH compliance for use in regulated industries and global markets
• Optimized thread engagement with 12 threads per inch and 0.19" diameter for secure fastening in pre-drilled No. 21 holes

Professional Applications & Engineering Value

These No. 10-12 thread forming tapping screws are specifically engineered to address common challenges in sheet metal fabrication and assembly. The thread forming design eliminates the risk of loose metal chips contaminating sensitive equipment while creating stronger, more reliable threads through material displacement rather than removal. The combination of hex head with external drive and fully threaded shank ensures maximum torque transmission and uniform stress distribution, preventing stripping and maintaining joint integrity in vibration-prone environments. The flanged design provides superior bearing surface, reducing the need for additional components and streamlining assembly processes in industrial manufacturing, HVAC systems, and electronic enclosures where sheet metal fastening demands precision and durability.

Specification Summary & Compliance

This No. 10-12 thread forming tapping screw features a 1" length with 0.19" thread diameter and 12 threads per inch, designed for use with No. 21 drill bits (0.159" diameter) in materials up to 0.025" thickness. The screw meets standard dimensional requirements for Type A tapping screws with right-hand threading and fully threaded configuration. Manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and suitability for industrial applications requiring certified components.
