S-90410A197 8-32 x 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 410 stainless steel construction, ideal for harsh industrial environments and extended service life
• Efficient thread cutting action with Type F design creates precise threads in brass, cast iron, and sheet metal without pre-tapping
• Reliable drive engagement from the Phillips No. 2 drive, reducing cam-out risk and ensuring secure installation
• Full 3/4" threading provides maximum grip and holding power across the entire fastener length
• Coarse UNC thread pattern delivers faster installation and superior performance in softer materials
• Pan head design offers a standard, low-profile finish for flush or slightly raised applications
• Environmental compliance with RoHS 3 and REACH standards ensures safe, regulated use in global markets

Professional Applications & Engineering Value

These 8-32 UNC thread cutting screws are precision-engineered to solve common assembly challenges in metalworking and fabrication. The 410 stainless steel composition provides excellent strength and rust resistance, while the thread cutting (Type F) design eliminates the need for separate tapping operations in materials like brass, cast iron, and sheet metal. This reduces labor time, minimizes tooling costs, and prevents thread stripping. The Phillips pan head and coarse UNC threads ensure quick, secure fastening in HVAC, automotive, and machinery assemblies, delivering consistent performance where vibration resistance and durability are critical.
