Nuts
A hex jam nut is a low-profile type of nut, typically half as tall as a standard nut. It is commonly used as a type of locknut, where it is "jammed" up against a standard nut to lock the two in place. It is also used in situations where a standard nut would not fit. Hex jam nuts are thinner than a standard hex nut but have the same dimension across the flats and corners.
Application:
- Hex jam nuts have many common applications like a jam nut can be threaded onto a bolt and run tight against the standard nut which will lock the nut in place and prevent it from backing off. Jam nuts can also be used in situations where a threaded rod must be rotated. Jam nuts are sometimes used for leveling purposes as well.

The purpose of inserting nuts is to create a stable and secure hold with the bolt. In certain objects, particularly those made of wood, bolts may gradually pull out over time. Insert nuts to prevent this from happening by gripping the object. The exterior threading will bite into the object during insertion.

Hex Nuts
Hex nuts are six sided general purpose nut with internal screw threads. Hex nuts are one of the most common hexagonal fastener with internal threads that screws on to the shank of a hex head cap screw or other bolts.
Application:
- Hex nuts are used in a variety of applications, including construction, industrial machinery, and household items. They are commonly found in applications such as securing wheels on cars and trucks, attaching parts to machinery, and fastening furniture and other household items

Nylon Insert Lock Nuts
Nylon nuts are the fasteners having nylon filling in the center which ensures the minimum damage to the material component that requires repeatedly assembly and disassembly. The nylon present in its center also locks the moisture and completely seals the bolt in place
Application:
- Used in buildings, on bridges, and in railroad equipment.
