A Bolt Lock Nut 19 No. 2.5" is a specialized fastener used to securely hold bolts in place and prevent them from loosening due to vibration or movement. It has a thread size of 19 No. and fits 2.5-inch bolts. These lock nuts are commonly used in heavy machinery, agricultural tools, vehicles, and construction work. They often feature a nylon insert (nyloc) or a deformed thread design, creating additional friction to maintain a tight, stable connection even under pressure.
