Because of their shape, cap nuts are often referred to as acorn nuts. But regardless of what people call them, they play a valuable role in the manufacturing industry. Many companies depend on powerful machinery that operates at a high level consistently in order to remain successful, so protecting even the smallest parts is a nuts. Nuts, bolts, and all of the other little pieces needed to properly assemble a machine need to be kept in proper working condition for it to remain accurate consistently. So businesses who want to avoid dangerous malfunctions or costly shutdowns will have to invest in the right nut covers and other items to make sure their machines do not fail.
The main purpose of cap nuts is to protect bolts from becoming damaged. Some companies will use nylon nuts that are durable enough to be taken apart and put back together again over and over on certain machines, but, more often than not, steel is the choice. Steel is stronger than other materials, which means it provides the most sturdy support for powerful equipment. However, it could rust or become unthreaded over time, especially in the wrong elements. The right covers will keep moisture and dirt off of the bolts, helping them maintain their strength and stay in place.
An added benefit to using cap nuts is that, quite simply, they are more aesthetically pleasing than other items. In most factories and production facilities, aesthetics are the last thing that owners and managers worry about. However, it is always a good thing to spruce up machines, especially if a facility gives lots of tours or hosts guests. Rounded chrome acorn nuts can hide rust and unsightly bolts from any set of eyes.
While acorn nuts and similar small items are needed on most production machines, they are hardly the only tools needed to keep machines running properly. Threaded standoffs are used for wire management and keeping circuit boards elevated above a surface, and rubber grommets prevent metal pieces from cutting wires. The small grommet used in for shoelaces is generally known as an eyelet. But no matter what nickname people give it, the grommets, standoffs, and acorn nuts used on powerful machines are generally more important and valuable. They protect far more than just a new pair of shoes.
