S-92210A718 1/2"-13 x 1 3/4" 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 extended service life in harsh environments
• Exceptional tensile strength rated at 70,000 psi ensures reliable performance in heavy-duty applications
• Precision Class 3A thread fit provides secure fastening with minimal play and vibration resistance
• Optimized flush mounting with standard 82° countersink angle and flat head design for smooth surface finishing
• Easy installation and removal through 5/16" hex drive design requiring common tools
• Full threading coverage along the 1-3/4" length maximizes grip strength and load distribution
• Regulatory compliance assurance meeting ASME B18.3 standards with RoHS 3 and REACH environmental directives

Professional Applications & Engineering Value

These 1/2"-13 UNC flat head screws deliver critical engineering advantages in demanding industrial environments. The 18-8 stainless steel composition combined with passivated finish creates a robust barrier against corrosion, making them ideal for marine, chemical processing, and outdoor applications where moisture and chemicals are present. The Class 3A thread fit ensures precise engagement with mating components, eliminating loosening under vibration while the coarse UNC threading facilitates quick assembly in production lines. The hex drive design provides superior torque transmission compared to slotted alternatives, reducing tool slippage and damage to fastener heads. These fully threaded screws are engineered for applications requiring maximum clamping force across the entire fastener length, from heavy machinery assembly to structural frameworks where reliability cannot be compromised.

Specification Summary & Compliance

Manufactured to exacting ASME B18.3 specifications with Class 3A thread fit tolerances for precision assembly. The UNC coarse thread pattern (1/2"-13) with right-hand threading follows industry standards for compatibility. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations ensures safe use across regulated industries. Mechanical properties include Rockwell B55 hardness and 70,000 psi tensile strength for demanding applications.
