S-91850A039 1 1/8"-7 Hex Nuts

Key Features & Benefits at a Glance

• Exceptional corrosion resistance from 316 Stainless Steel construction, ideal for harsh chemical and marine environments
• Superior torque transmission and grip due to the extra wide hex profile (1 13/16" width), reducing tool slippage
• Reliable, quick assembly with coarse UNC threads and Class 2B fit, ensuring consistent engagement and vibration resistance
• Heavy-duty load bearing capacity from the robust external hex drive and substantial 1 7/64" height
• Enhanced safety and compliance by meeting RoHS 3 and REACH environmental standards
• Broad industrial compatibility with right-hand thread direction and inch measurement system

Professional Applications & Engineering Value

This extra wide hex nut in 316 Stainless Steel addresses critical challenges in demanding sectors like chemical processing, marine engineering, and offshore infrastructure. Its coarse UNC thread and Class 2B thread fit provide excellent resistance to vibration loosening, maintaining joint integrity under dynamic loads. The external hex drive and enlarged width allow for higher torque application with standard tools, speeding up installation in confined or high-stress assemblies. The material's superior corrosion resistance against chlorides and acidic agents extends service life, reducing maintenance frequency and downtime in aggressive operational environments.
