S-91655A254 Length 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
• Efficient thread forming capability with Type A/AB design creates strong, permanent threads in sheet metal without pre-tapping
• Enhanced load distribution through the 0.423" flange diameter provides superior clamping force and prevents pull-through
• Optimized installation efficiency with square drive No. 2 and pan head design ensures secure tool engagement and reduced cam-out
• Maximum thread engagement with fully threaded 2" length and pointed tip for precise alignment and faster penetration
• Precision drilling compatibility designed for No. 21 drill bit (0.159") with 0.025" maximum drilling thickness specification
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for global manufacturing applications

Professional Applications & Engineering Value

These zinc-plated steel flanged tapping screws deliver exceptional performance in sheet metal fabrication and assembly operations. The thread forming Type A/AB design eliminates the need for separate tapping operations, creating strong, vibration-resistant threads that withstand dynamic loads. The integrated flange provides superior bearing surface, distributing clamping force evenly to prevent material deformation in thin-gauge applications. With fully threaded construction and right-hand threading, these screws offer maximum pull-out resistance and consistent performance in automotive, HVAC, and electrical enclosure assemblies where reliable fastening in sheet metal is critical for structural integrity and long-term durability.

Specification Summary & Compliance

This No. 10-12 x 2" tapping screw features precise 0.19" thread diameter with 12 threads per inch and standard thread tolerances. The pan head with square drive No. 2 ensures secure installation, while the pointed tip facilitates easy starting in pre-drilled holes. Manufactured to industry standards for thread forming screws, this product is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting the latest environmental regulations for industrial fasteners.
