Industrial 1-1 8 - 7 (1.125-7) Self-Locking Hex Nut

Industrial 1-1/8-7 self-locking hex nut, crafted from Steel Grade C, provides a durable fastening option for bolts in industrial equipment and machinery. The thread size is 1-1/8-7, corresponding to a 1.125 inch diameter bolt with seven threads per inch, making it compatible with standard bolts of the same size. The self-locking feature offers resistance to loosening under typical vibration and dynamic loads encountered in manufacturing and maintenance environments, helping maintain preload over time. Constructed from Grade C steel, this hex nut delivers reliable strength for general-purpose fastening tasks where a secure, long-lasting connection is required. Its six-flat hex shape facilitates using standard wrenches for straightforward tightening and removal, contributing to efficient assembly and field service. This nut is well-suited to industrial fastening applications that specify a 1-1/8 inch bolt and Grade C steel hardware, including machinery, equipment, and structural assemblies where dependable locking performance is needed.
