S-92805A266 10-32 x 3/4" ASME B18.3, ASTM F879, MIL-DTL-18240 Stainless Steel Thread-Locking Hex Drive Flat Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments
• Reliable vibration resistance through nylon patch thread locking that maintains integrity from -65° to 250°F
• Precise installation and removal with 1/8" hex drive design preventing cam-out and tool slippage
• Exceptional thread engagement with Class 3A fit ensuring tight tolerances and reduced cross-threading risks
• High strength-to-weight ratio delivering 70,000 psi tensile strength for demanding applications
• Consistent flush mounting with standard 82° countersink angle and flat head profile
• Full thread coverage along the 3/4" length providing maximum fastening contact area

Professional Applications & Engineering Value

Engineered for precision assemblies requiring vibration-resistant fastening solutions, these 10-32 UNF flat head screws combine 18-8 stainless steel's corrosion resistance with advanced nylon patch locking technology. The fine UNF threads and Class 3A thread fit ensure secure engagement in tapped holes, preventing loosening in machinery, electronic enclosures, and automotive components. The hex drive configuration allows high-torque installation without damaging the fastener head, while the fully threaded design distributes clamping force evenly across the entire length. These screws solve critical challenges in applications where thermal cycling, chemical exposure, and dynamic loads compromise fastener integrity.
