S-94895A586 1 1/4"-7 Hex Nuts

Key Features & Benefits at a Glance

• Exceptional strength and reliability with Grade 8 classification, ensuring high load-bearing capacity and resistance to loosening under vibration in demanding industrial environments.
• Superior corrosion resistance from the black-oxide steel finish, extending service life and reducing maintenance needs in harsh or outdoor applications.
• Optimized for quick assembly thanks to the coarse UNC thread, which allows for faster installation and reduces the risk of cross-threading compared to fine threads.
• Precise and secure thread fit with Class 2B tolerance, providing consistent engagement with mating bolts for reliable, vibration-resistant connections.
• Industry-standard external hex drive design enables easy installation and removal using common wrenches, improving workflow efficiency on the job site.
• Compliance with major environmental and safety regulations including RoHS 3 and REACH, ensuring the nut is safe for use in regulated industries and global supply chains.
• Robust dimensional profile with a 1 7/8" width and 1 1/16" height, offering a solid grip and ample bearing surface for high-torque applications.

Professional Applications & Engineering Value

This Grade 8 hex nut is engineered to address critical challenges in heavy machinery, construction, and automotive assemblies where vibration resistance and long-term durability are paramount. The black-oxide steel construction not only provides a protective layer against rust and corrosion but also maintains the nut’s structural integrity under extreme stress. Its 1 1/4"-7 UNC coarse thread design ensures rapid installation in thick materials or where alignment is challenging, reducing labor time while maintaining a secure fit. The Class 2B thread fit guarantees consistent performance with standard right-hand threaded bolts, minimizing the risk of premature failure. Ideal for structural frames, industrial equipment, and high-torque fastening systems, this nut delivers reliable performance that meets the rigorous demands of professional engineering applications.
