The VALUE COLLECTION 1-N-75F is a 3/4-16 UNF hex lock nut with a nylon insert locking mechanism, manufactured from 18-8 stainless steel. The nylon insert creates interference against the mating thread to resist loosening caused by vibration and torque cycling. At 7/8 inches in height and 1-1/16 inches across the flats, this nut fits standard 3/4-16 UNF fastener assemblies. The 18-8 stainless steel construction provides corrosion resistance suitable for wet, marine, or chemically exposed environments. Right-hand thread direction follows standard fastener convention. It is sold in individual pieces with a minimum order quantity of five units.
This hex lock nut is used wherever a 3/4-16 UNF threaded connection requires a positive locking solution. Typical applications include mechanical assemblies in HVAC equipment, plumbing brackets, electrical enclosure hardware, pool equipment mounting, and general trade fabrication work. The nylon insert style is a common choice when the joint may experience intermittent vibration or thermal cycling, as the insert maintains preload without the need for thread-locking compounds. It is appropriate for both new installation and field repair work by mechanical and maintenance trades.
Designed for use with 3/4-16 UNF threaded fasteners in inch-measurement assemblies requiring a nylon insert hex lock nut.
Installation is performed by mechanical, maintenance, or trade technicians using a standard open-end or combination wrench sized to 1-1/16 inches across the flats. Ensure mating threads are clean and free of debris before driving the nut to avoid damaging the nylon insert. Do not reuse nylon insert lock nuts after full removal, as the insert loses clamping effectiveness once displaced. Follow applicable mechanical codes and equipment manufacturer torque requirements for the specific assembly.
