So, have you never seen a knurled nut, nor know what it is? OK, here we go- a knurled nut uses a knurled finish instead of the more traditional hexagonal design. The knurled design lets the nut get tightened or even loosened by hand. If you work with fasteners on a normal basis, you no doubt understand how difficult this can be without a wrench. You can usually find them in electrical components or musical instruments, and even certain automobiles. While nontraditional, and not heavily used, they do come in handy and can be really convenient in certain situations.
Use Your Hands
Knurled nuts are usually used on small rods and bolts. This is mainly because they’re designed to be turned by hand. Large bolts need a wrench to tighten or loosen them- the average person doesn’t have that much arm and hand strength. If you’re dealing with one that just won’t come loose for whatever reason, try either placing a wash rag over it, or putting on a pair of gloves. Both may give you the traction you need to get the nut free. Again, keep in mind that these fasteners are designed to be easily manipulated. Don’t expect to be able to use them for anything that’s heavy duty, or labor intensive. They’re just not built for it.
A Tool With Many Purposes
This is what separates knurled nuts from other fasteners. While most nuts and bolts are meant to be sturdy, firm, and dependable, knurled’s are built to be loosened and tightened repeatedly. Keeping them oiled is a good idea, as they can grow to stick or even rust over time, leaving you without the ability to get them free from whatever it is they’re built into. Keep the little things like this in mind.
Knurled nuts are a great way to secure tools, instruments, and certain types of electronics while at the same time keeping them easy to open up. If you mod electronics, tinker with the inside of your musical instruments, or like tuning and repairing your tools and machines, they’re truly invaluable.
