S-90054A203 Length 1 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
• Enhanced torque transmission through external hex/slotted drive design, preventing tool slippage during installation
• Efficient material displacement with thread forming technology that creates stronger, vibration-resistant threads in sheet metal
• Distributed load bearing thanks to the integrated flange design, reducing surface pressure and preventing material deformation
• Quick penetration and alignment with pointed tip geometry, streamlining installation in sheet metal applications
• Maximum thread engagement through fully threaded 1-1/2" length, ensuring secure fastening across the entire material thickness
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for safe industrial use worldwide

Professional Applications & Engineering Value

These No. 8 thread forming tapping screws deliver exceptional performance in sheet metal fabrication where traditional fasteners often fail. The zinc-plated steel construction provides reliable corrosion protection in industrial environments, while the external hex/slotted drive accommodates both manual and powered installation tools. The thread forming design eliminates the need for pre-tapped holes, creating stronger, vibration-resistant connections by cold-forming mating threads in the base material. This engineering approach prevents loosening under dynamic loads and distributes clamping force effectively through the integrated flange, making these industrial fasteners ideal for HVAC systems, electrical enclosures, and machinery panels where reliability is critical.

Specification Summary & Compliance

This No. 8-15 thread forming screw features precise 0.164" thread diameter with 15 threads per inch and 1-1/2" fully threaded length. The hex head design with 1/4" width and 0.141" height provides optimal tool engagement, while the 0.348" flange diameter ensures secure load distribution. Designed for use with No. 29 drill bit (0.136" diameter) in sheet metal up to 0.025" thickness. Manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards for industrial safety requirements.
