Iron Material Galvanized Hex Nut Insert Lock Metric Standard Nuts With Zinc Color

Product Description

Hex Nuts are used to lock. Consistent torque at tension allows for reliable joint integrity.

Prevailing torque differentiates a locknut from a free spinning nut based on a value of how much torque is required during installation before clamp loading. For example, on a nylon-insert nut, it is the torque needed to overcome the resistance of the nylon dragging across the mating thread. This torque value is usually not very high relative to final installation torque. Tolerance ranges for torque are specified in some standards such as (ISO, DIN, IFI, ASME, SAE, AN-, MS-, NAS- NASM-). We attach the torque table below in specification.

A lock nut is a kind of nut which resists loosening when properly threaded onto a bolt. Nut and bolt fasteners are much common in industry and home applications. Many are universal in application, while others work best under certain circumstances.

Applications

Automotive industry, machinery manufacturing, pneumatic tools, furniture hardware, construction and so on.

Features

Wide range of applications, characterized by a larger fastening force, the disadvantage is that there must be sufficient space for installation, the installation can be used to live wrenches, open-end wrenches or glasses wrenches, the above wrenches require a lot of space for operation.
