S-90096A357 3/8"-16 x 5" ASME B18.6.3, SAE J933 Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Exceptional thread-cutting performance creates precise mating threads in aluminum, brass, cast iron, and sheet metal without pre-tapping
• Enhanced load distribution through integrated flange design prevents surface damage and improves joint integrity
• High-torque installation capability with external hex drive head for secure fastening in high-vibration applications
• Reliable coarse thread engagement with UNC 3/8"-16 threading provides quick assembly and strong holding power
• Full-length threading ensures maximum grip along the entire 5" length for superior pull-out resistance
• Industry compliance assurance meets ASME B18.6.3 mechanical specifications and RoHS 3 environmental standards

Professional Applications & Engineering Value

These heavy-duty flanged tapping screws deliver exceptional engineering value in metal fabrication and assembly operations. The zinc-plated steel construction provides reliable corrosion protection while the thread-cutting design eliminates the need for separate tapping operations, significantly reducing installation time and labor costs. The external hex drive enables high-torque application without cam-out, ensuring secure fastening in aluminum, brass, cast iron, and sheet metal applications. The integrated flange distributes clamping force over a wider surface area (0.78" diameter), preventing material deformation and maintaining structural integrity in high-stress environments. These fully threaded screws maintain consistent holding power throughout their entire 5" length, making them ideal for thick-section assemblies where vibration resistance and pull-out strength are critical performance requirements.

Specification Summary & Compliance

This 3/8"-16 UNC coarse thread tapping screw features precise Class 2A thread tolerances and meets ASME B18.6.3 mechanical specifications (SAE J933) for dimensional accuracy and performance reliability. The product is manufactured in compliance with RoHS 3 (2015/863/EU) environmental standards, ensuring restriction of hazardous substances. The screw's thread cutting design (Type F) and 0.339" drill bit size (Size R) recommendation provide optimal performance in the specified material applications, delivering consistent threading quality and installation reliability for industrial fastening requirements.
