S-90054A201 Length 1 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments
• High-torque installation capability through the external hex/slotted drive design, ensuring secure fastening without stripping
• Efficient thread-forming action that creates strong, permanent threads in sheet metal without pre-tapping
• Integrated flange design provides wider bearing surface for improved load distribution and vibration resistance
• Full threading along the 1-1/4" length delivers maximum grip and holding power in thin materials
• Precision compatibility with standard No. 29 drill bits (0.136" diameter) for streamlined installation processes
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for global industrial applications

Professional Applications & Engineering Value

These No. 8-15 thread forming tapping screws are engineered specifically for sheet metal fabrication applications where reliable fastening in thin materials is critical. The zinc-plated steel construction provides essential corrosion protection for industrial environments, while the hex flange design eliminates the need for separate washers, reducing installation time and component count. The thread forming capability creates strong, permanent threads in sheet metal up to 0.025" thickness without chip formation, preventing contamination in sensitive assemblies. The combination of external hex/slotted drive offers flexibility for both power and manual tooling, making these flange screws versatile for various production scenarios from HVAC systems to electronic enclosures and automotive components.

Specification Summary & Compliance

This No. 8 tapping screw features a 0.164" thread diameter with 15 threads per inch in right-hand direction, manufactured to standard thread forming specifications (Type A/AB). The 1-1/4" fully threaded length with pointed tip ensures optimal engagement in sheet metal applications. The product maintains dimensional accuracy with a 1/4" hex head width and 0.141" head height for consistent performance. Compliance is verified with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and global market acceptance for industrial fastener applications.
