yes
Spray it with a penetrating oil leave it for a few hours then try to loosen it, or heat the nut up quickly and try to remove it then.
Heat the nut (preferably with a torch!) and cool the bolt (screw).
When an object is heated, it will expand. When cooled it will contract. So if you quickly heat and cool a stuck nut and bolt, it can break apart the rust or whatever is causing it to stick.
A nut is called screw when its head is tightend in component .but in case, tight of nut is not possible without bolt.since screw is tight without nut bolt it is not possible in case of nut.
That's correct. This particular wrench holds the nut or bolt head better than any other wrench.
on the inside of your wheel there is a little nut screwed to the bolt on the trucks, use a wrench to tighten that
How is a nut like a bolt
A box wrench is always the most effective to loosen tight nuts.
No. A nut and bolt are a matched set of fasteners. The bolt goes into or through the object it will secure, the nut is spun on to the bolt and snugged up tight to complete the fastening. A screw is a single fastener driven into (usually) wood - there is no nut used with it. There are also screws for use in metal, but they do not hold as securely as a nut and bolt.
how to loosen a tight nut
A bolt without a nut or a head is called a stud.
It could be a worn stud or worn nut. If it's really bad, you may need to install a new stud. If a new nut doesn't fit tight, you could try putting a jam nut on top of the rocker nut.
