S-92198A861 3/4"-10 x 7" ASME B18.2.1 18-8 Stainless Steel Hex Head Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance from 18-8 stainless steel construction, ideal for harsh industrial environments and reducing long-term replacement costs.
• Superior mechanical strength with 80,000 psi tensile strength and Rockwell B70 hardness, ensuring reliable performance under high-stress loads.
• Optimized for high-speed assembly with a coarse UNC thread and Class 2A fit, providing faster installation and reduced risk of cross-threading.
• Secure and efficient fastening enabled by the 1 1/8" external hex head, allowing for high-torque application with standard tools.
• Versatile partial threading on a 7" length offers a non-threaded shank for precise shear load management in structural connections.
• Guaranteed dimensional consistency and interchangeability, manufactured in full compliance with the rigorous ASME B18.2.1 standard.
• Safe for regulated industries as the material and finish are fully compliant with RoHS 3 and REACH environmental directives.

Professional Applications & Engineering Value

This 3/4"-10 UNC hex head screw is engineered to solve critical challenges in heavy machinery, structural steel framing, and large-scale equipment assembly. The 18-8 Stainless Steel provides a robust defense against rust and chemical exposure, significantly extending service life in demanding conditions. Its coarse thread and Class 2A fit are specifically chosen to prevent galling and ensure rapid, reliable assembly even in less-than-ideal field conditions. The partially threaded design is a key engineering feature, concentrating the clamping force on the threaded portion while the smooth shank bears against clearance holes to minimize shear stress. This combination of a durable external hex drive and high tensile strength makes it an indispensable component for applications requiring both immense clamping force and corrosion resistance.

Specification Summary & Compliance

This screw is manufactured to precise inch system dimensions: a 3/4"-10 UNC thread with a Class 2A tolerance for consistent fit. The thread is right-hand direction with a minimum thread length of 2" on the overall 7" body. It conforms to the ASME B18.2.1 standard for hex head cap screws. The product is confirmed to be RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring it meets strict environmental and safety regulations for hazardous substances.
