S-92198A934 1"-8 x 10" ASME B18.2.1 18-8 Stainless Steel Hex Head Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance thanks to 18-8 Stainless Steel construction, ideal for harsh environments.
• Superior mechanical strength with 80,000 psi tensile strength and Rockwell B70 hardness for reliable load-bearing performance.
• Optimized for high-torque applications featuring an external hex drive and a large 1 1/2" head width for secure tool engagement.
• Precise and reliable thread fit with Class 2A thread tolerance ensuring consistent assembly and vibration resistance.
• Enhanced durability in coarse threading applications due to the 1"-8 UNC coarse thread spacing, reducing the risk of cross-threading.
• Versatile partial threading design on a 10" length allows for both secure clamping and unthreaded shank benefits.
• Compliance with major industry standards including ASME B18.2.1, RoHS 3, and REACH for guaranteed quality and environmental safety.

Professional Applications & Engineering Value

This 1"-8 UNC Hex Head Screw is engineered to address critical challenges in heavy-duty industrial applications where corrosion resistance and structural integrity are paramount. The 18-8 Stainless Steel material provides excellent protection against rust and chemical exposure, making it suitable for outdoor, marine, and chemical processing environments. Its partially threaded design with a Class 2A thread fit ensures that the unthreaded shank bears shear loads effectively while the coarse UNC threads facilitate quicker assembly and better performance in softer materials or where debris is present. The external hex drive and substantial head dimensions allow for high torque application, preventing stripping and ensuring a secure, long-lasting fastening solution in construction, machinery, and infrastructure projects.

Specification Summary & Compliance

This screw adheres to precise dimensional standards with a Class 2A thread fit and UNC thread type for consistent performance. It is manufactured in compliance with ASME B18.2.1 specifications and meets environmental regulations including RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), ensuring it is free from hazardous substances and suitable for global industrial use.
