bolts

[marsaday]

Where can i get some bolts from which have no ends on them. I will be bolting 2 C channels to a huge joist/truss. i have to span about 90mm, so 110mm bolts should be ok. i want to be able to tighten a nut at both ends you see. They want to be M12's.

is there somewhere which will cut the lengths required exactly for me?

Buy some studding from a Builders Merchant and use a hacksaw to cut the length required.

if you hack saw the bolt down will it still work on that end with a nut?

i need 70 x 110mm, 6 x 170mm, 30 x 120mm bolts. is there no one who will cut what i need.

what is studding?

Ahh, you mean you need 70No. 110mm lengths etc? Well that would take a bit of time to cut those yourself I concede. Tis true it'd be a lot easier to buy bolts rather than cut down studding to make your own. Try a specialist, someone like Namrick, you'll probably have a local supplier near you though. Will be cheaper than a Builders Merchant.

Studding is a continuous length of thread bar with no bolt head on one end BTW so you'd wind a nut and washer onto each end.

You could see how much a small engineers shop would charge to cut the studs for you though. Might be cheaper than buying all those bolts.

So something like these:

Strong-tie let me down tho and this one is from the US listings.. places like screwfix, B&Q do lengths of threaded rod you can cut down.. (cheaper) or look for threaded bar for set lengths..

thanks guys i will have a look at what you mention.

Top tip: When cutting threaded bar always ensure that you have a pair of nuts on the bar at the point you wish to cut. This is nothing to do with S&M by the way.

Use an angle grinder with a metal cutting disc.

So let's say you wish to cut a piece of bar 100mm long. Wind a pair of nuts onto the bar and continue winding until the nuts are 100mm down the bar. Space the nuts slightly apart so that you have room for the cutting disc, i.e. 10mm apart..

When you have finished cutting you will have one piece of bar 100mm long and what ever is left of the original. Each piece will have a nut on the end.

Next, use the grinder to round the ends of the bar.
then, wind the nuts off the bar in the direction of the rounded ends.

This will ensure that the nuts cut you a decent thread.

sounds good, but i hope to get them cut my someone if i can.

Dont want to risk putting your own nuts on the bar so close to an angle grinder.. well can understand that..

(either way was a solid tip)
