Professional Applications & Engineering Value
This heavy-duty hex nut is engineered to solve critical fastening challenges in demanding sectors like chemical processing, marine equipment, and structural assemblies. The 316 stainless steel material delivers outstanding corrosion resistance, even when exposed to chlorides or acidic conditions, while the coarse thread (1 3/4"-8) and Class 2B thread fit enable quick, secure installation with minimal risk of galling. Its extra wide hex profile allows for higher torque application, preventing rounding and ensuring long-term joint integrity in heavy-duty fastening systems. Compliant with ASTM A194 and built to Grade 8M mechanical properties, this nut maintains performance under high stress and vibration, making it a reliable choice for engineers prioritizing safety and durability.
Specification Summary & Compliance
This nut meets ASTM A194 specifications and is rated Grade 8M for high-strength applications. Threads are UN coarse (1 3/4"-8) with a Class 2B fit for consistent engagement. Dimensions include a width of 2 3/4" and height of 1 3/4". The product is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring adherence to environmental and safety regulations.
