Description   Nuts are a type of hardware fastener with a tapped inner diameter. They are used with a mating threaded bolt or rod to secure components. There are many sizes and varieties of nuts; each with a particular fastening purpose. Some nuts can be applied without tools, and others may have special designs to prevent the nut from loosening.   Nut Operation   Most nuts require a rotational force around the bolt threads for application, though some...

Q:
From your perspective, which companies are creating the most innovative nuts?
13 answers
Answers:
I make my own. Not a business that innovation has much future, nuts are like "bricks" in building construction . Most ideas for types have already been explored.

Applications and UseTop

Q:
What are some of the applications you have used nuts for?
29 answers
Answers:
Nuts are used to join two or more parts together with Bolt. There are different types of nuts; they are called fasteners also. The most commonly used type is Hex Nut. These are used in various assemblies like tools, panel boards, automobile industries, machinery industries, lighting industries etc. Cage nuts are used in Automobile industries, and have a square head. Weld nuts are used in sheet metal industries where nut is having one small step, which is inserted in hole provided in particular sheet metal part and welded. There are rivet nuts, again used thin sheet, metal industries. These are inserted in hole provided in sheet metal and riveted with special tools, where welding will spoil the aesthetic finish of the product. One more type is Clinch nut, almost like rivet nut, but having knurled portion around shaft diameter and saw type teeth at the bottom of face wresting on sheet metal for better gripping.

This question does not make sense, all nuts are only used on bolts - threads that they will fit.
~Chris P, Engineer, Whitby, United Kingdom
Spacers, standoffs and bushings when other materials could not be found quickly.

Q:
Do you know of any disastrous mistakes that occurred due to the incorrect usage of nuts?
7 answers
Answers:
Locking nut is not insurance for loosing joint; joint will fail under vibration and checking is needed from time to time. Disastrous was about a knife assembled in an agricultural cutting and rotating device, considered maintenance free due to locking nut use.
~Guido G, Research & Development, Joinville, Brazil
Loose parts on any assembly will create a health hazard, when the vibration due to wear and time working were not reviewed correctly.
~Ricardo Avila, Consulting, Monterrey, Mexico
Once I used a non locking nut only to have the skate wheels come off while skating!

~Ricardo Avila, Consulting, Monterrey, Mexico
Always use standard sizes when possible. Get samples first.
~David R, Purchaser, Huntsville, AL
Do not hesitate use good expensive nuts. They are worth it.
~Alon Lebovitz, Design Engineer, Beer Sheva, ISRAEL
First be sure about supplier knowledge and liability.
~Guido G, Research & Development, Joinville, Brazil
You get what you pay for so don't go cheapest price.
~Bill R., Production Engineer, Dahlgren, VA
Any vibration use locking nuts like nyloc.
