Value Collection 94018 Hex Lock Nut 1-8 Unc 18-8 Ss 5-pack

Product Description

The VALUE COLLECTION 94018 is a 1-8 UNC hex lock nut with a nylon insert locking mechanism, manufactured from 18-8 stainless steel. The nylon insert deforms around the mating thread when the nut is driven to final position, creating resistance to loosening from vibration and thermal cycling without requiring additional locking hardware. At 35/64 inches high with a 1-7/16 inch width across flats, this is a full-size, heavy-duty fastener suited to structural and mechanical assembly applications. Right-hand thread direction follows standard UNC convention. Sold in a pack of 5.

This nut is used in mechanical assemblies, structural connections, and equipment installations where corrosion resistance and vibration resistance are both required. The 18-8 stainless steel construction makes it appropriate for wet environments, outdoor installations, HVAC equipment mounting, and plumbing fixture connections. Maintenance technicians, pipefitters, millwrights, and general contractors regularly specify nylon insert lock nuts in this size range for equipment anchoring and flange connections.

Key Features

Compatibility

Designed for use with 1-inch diameter, 8 threads-per-inch UNC right-hand threaded fasteners and threaded rod in standard inch-measurement assemblies.

Installation Notes

Install using a standard hex wrench or socket sized to 1-7/16 inches across flats. Nylon insert lock nuts are single-use fasteners — the nylon insert is deformed during initial installation and may not provide reliable locking torque if removed and reinstalled on the same thread. Ensure mating threads are clean and free of debris before assembly. Follow applicable mechanical or structural codes for final torque and fastener specifications.
