S-92210A011 0-80 x 3/16" ASME B18.3 Stainless Steel Hex Drive Flat Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction and passivated finish for long-lasting performance in harsh environments
• Precise thread engagement with Class 3A fine thread fit ensures secure fastening and vibration resistance in critical assemblies
• High strength-to-weight ratio delivering 70,000 psi tensile strength and Rockwell B55 hardness for reliable load-bearing capability
• Optimal flush mounting with standard 82° countersink angle and flat head design for smooth surface finishes
• Efficient installation using hex drive (0.035") for secure tool engagement and reduced stripping risk
• Full thread coverage along the 3/16" length provides maximum grip and distribution of clamping force
• Regulatory compliance meeting ASME B18.3 specifications and environmental standards (RoHS 3, REACH) for global applications

Professional Applications & Engineering Value

These 0-80 UNF flat head screws deliver exceptional value in precision engineering applications where space constraints and surface finish requirements are critical. The 18-8 stainless steel material combined with passivated finish provides superior corrosion resistance for medical devices, aerospace components, and electronic enclosures exposed to demanding environments. The Class 3A thread fit and fine threading ensure precise alignment and vibration resistance in miniature assemblies, while the 82° countersink angle allows for seamless flush mounting in machined surfaces. These fully threaded fasteners maintain consistent clamping force across the entire 3/16" length, making them ideal for securing thin materials and precision components where reliability is paramount.
