cutting bolts
Turbo Mini Forums

Hi,

I did a search but couldnt find anything.

Can anyone tell me, what is the best way to cut a bolt to length. I keep damaging the thread and cant engage it afterwards.

i always put a nut on beforehand then remove it after cutting it to clean the threads.

I used to put a nut on before cutting as Anton said but now I simply cut parrellel to a thread. Once you keep the hacksaw perpendicular to the bolt face the threads will be fine

yep, as above pop a nut on,

I alwaus file the cut bit smooth, and taper the thread just a little with either a file or a grinder.

Yeah, keep the saw in the same direction of the thread and putting a nut on cleans the threads up when you remove it.

Dead easy.

i always pop a nut on to help clean the threads, then clean the end up on a grinding wheel very quickly

File or grind a chamfer on the end once its cut helps too

Put your comments into practice this afternoon and it helped a lot. Many thanks.

practice!

Hacksaw and needle files. always ensure you file a chamfer on the lead thread and take a thou or so off of the crown of the lead thread.

Own the day

I always go for a finer hacksaw blade (32tpi), if i've got a few to cut i usually go for a new blade. Go for a decent branded blade. Nothing worse than going at tough bolts with a blunt blade. Make sure your saw is tight and the blade mounted nice and square.

Soft jaws on your vice are good, you can make your own using some soft aluminium sheet cut and folded around the jaws. You can get plastic faced ones to.

I tend to try and grip the length of thread i'm cutting off in the vice. You can lock two nuts together to get a purchase on other lengths or just go carefull in the soft jaws. You can use a nut on the thread as a guide and to protect the thread if you need (again two locked together is better if you have room).

I clean the bolts up on a bench grinder. First clean the face then angle the bolt so that the wheel grinds towards the cut end and gently chamfer the end. Grinding at this angle tends to leave the lead thread pretty clean. If no bench grinder then file in a similar way.

if its a hex head, clampthe head and the bolt flats that you have wound down the head for extra support

If you are gripping it by the thread in a vice...use a softer material like wood or ally on the jaws

Unless its the bit your throwing away lol

In the 13's at last!.. Just

like the others say i put the nut on first, then i move the nut to where i want the cut to be, and cut along the edge of the nut. job done, easy peasy

As above I always put a nut on prior to cutting.

If theres not enough of the bit your cutting off to hold in the vice, I usually put two nuts on, lock them together and hold the nuts in the vice.

I usually use a thread file to clean up the threads after cutting.
