S-90410A190 8-32 x 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 410 stainless steel construction, ensuring long-lasting performance in demanding industrial environments
• Efficient thread cutting capability with F-type design that creates precise mating threads in brass, cast iron, and sheet metal without pre-tapping
• Enhanced driving stability through Phillips No. 2 drive and pan head combination, reducing cam-out and improving installation efficiency
• Optimal material engagement with UNC coarse thread spacing and full threading along the 1/4" length for maximum holding power
• Simplified installation process using standard No. 29 drill bit (0.136") for precise pilot holes, reducing assembly time and errors
• Regulatory compliance assurance meeting RoHS 3 and REACH environmental standards for global manufacturing applications
• Versatile application range specifically engineered for multiple metal substrates including sheet metal, cast iron, and brass components

Professional Applications & Engineering Value

This 8-32 UNC thread cutting tapping screw delivers exceptional engineering value in metal fabrication and assembly operations. The F-type thread cutting design eliminates the need for separate tapping operations, significantly reducing labor costs and assembly time in brass, cast iron, and sheet metal applications. The 410 stainless steel construction provides excellent corrosion resistance where environmental factors could compromise fastener integrity. With coarse UNC threading and full threading along the entire 1/4" length, this screw ensures maximum thread engagement and superior pull-out resistance in thin materials and cast components. The Phillips pan head drive system offers reliable torque transmission while maintaining a low-profile appearance ideal for finished products across automotive, HVAC, and industrial equipment manufacturing sectors.

Specification Summary & Compliance

This thread cutting tapping screw features precise 8-32 UNC coarse thread specifications with right-hand threading and fully threaded design for consistent performance. The fastener maintains standard dimensional tolerances with 0.164" thread diameter and 1/4" length for reliable interchangeability. Manufacturing compliance includes adherence to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global industrial applications and restricted substance compliance in international markets.
