S-90054A505 Length 3/4" 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 installation efficiency through external hex/slotted drive design providing multiple tooling options and secure torque application
• Eliminates the need for separate washers with integrated flange design that distributes load evenly and prevents material pull-through
• Optimal thread engagement with fully threaded pointed tip that facilitates precise alignment and reduces installation effort in sheet metal
• Reliable thread-forming capability creates strong, permanent threads in pre-drilled holes without requiring tapped threads
• Precise dimensional compatibility with 21/64" drill bit specification ensuring proper fit and maximum holding strength in 0.025" thick materials
• Comprehensive regulatory compliance meeting RoHS 3 and REACH standards for global manufacturing applications

Professional Applications & Engineering Value

These 3/8"-9 thread forming tapping screws deliver exceptional performance in sheet metal fabrication and assembly operations. The zinc-plated steel construction provides critical corrosion protection while maintaining high tensile strength, making these flanged hex head screws ideal for HVAC systems, electrical enclosures, and industrial machinery where vibration resistance is paramount. The thread forming design creates precise, cold-formed threads that eliminate chips and debris, ensuring clean installations in sheet metal applications. The combination of external hex drive and integrated flange allows for high torque application while distributing clamping force over a wider surface area, preventing material deformation and maintaining structural integrity in thin-gauge metals.

Specification Summary & Compliance

This flanged hex head tapping screw features precise inch measurements including 3/8" thread diameter with 9 threads per inch and 3/4" length. Manufactured as a Type A/AB thread forming screw with right-hand threading and fully threaded pointed tip design. The product maintains dimensional accuracy per industry standards and demonstrates full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global manufacturing requirements and restricted substance directives.
