About this item

Hillman 180165 nylon lock nut is a durable fastener designed for secure bolt connections. Made from alloy steel with a zinc finish, it features a nylon insert that grips bolts tightly, resisting vibration and loosening. Suitable for indoor and outdoor applications, it ensures reliable fastening in various environments. The hexagonal shape allows easy tightening with standard tools, and the coarse thread offers enhanced durability. Imported from the USA, it arrives quickly in India via ExpressBox, with all duties and GST handled, ensuring a hassle-free experience.

Reviewers report that Hillman nylon lock nuts stay in place even under vibration, making them ideal for machinery, automotive, and construction projects. The alloy steel construction withstands harsh weather, and the zinc coating prevents corrosion. Many Indian buyers appreciate the quick delivery and the secure fit, saving time and effort on repairs and assembly. Whether for industrial or DIY use, this lock nut offers a trusted, American-quality fastening solution, with the convenience of direct import and clear pricing.
