Bolt V screw

[Focus Owner]

what is your definition?

I class a bolt as having a shank. while a screw starts from the head. is my description. and what i have been taught.

I want to hear your descriptions

I will request a poll in a few days. when we have the various opinions

A bolt screws into a nut.
A screw doesn't, uses the medium that you are affixing to eg a self tapper into wood.

we need a i appreciate your comment button.
you could add more information to your agreement. by saying a bolt screws into a pre made thread. covering tapped holes.

I agree with what's been posted, a screw goes into a tapped hole or non tapped hole. Anything that has a nut on the end, is a bolt.

However, the exception is when a bolt holds something on, for example wheel bolts, they just go into a hole and are therefore screw-like, but the existence of the wheel before the medium that the bolt goes into makes it a bolt.

If that makes any sense at all

Helps if you use the correct screwdriver.

well that definition has gone down the pan. cause that can be used on a bolt as well.

My point exactly.

The tool used does not define the name of the fixing.

 

[jip0]

a screw is something that you need another person for

shh jipo
so what does define it cause the wood screw, screws my theory.
unless its a combination of both. so tapered end and starts from begining
if has a shank and tapered end.

when what do we do about pressure fixing whare the thread tapers

 

[Focus Owner]

got the american one from that document

2.1 Bolt
A bolt is an externally threaded fastener designed for insertion through the holes in assembled parts, and is normally intended to be tightened or released by torquing a nut.
2.2 Screw
A screw is an externally threaded fastener capable of being inserted into holes in assembled parts, of mating with a preformed internal thread or forming its own thread, and of being tightened or released by torquing the head.

so americans claim a bolt is not driven.

Generally speaking, bludvl_x19 has it correct as far as I'm aware, but I'm sure there will be exceptions.

A bolt screws into a nut.

A screw doesn't, uses the medium that you are affixing to eg a self tapper into wood.
