Hi All.

I have inherited what look like 8mm diameter, 12 t.p.i. ACME Threaded, 4 Start Linear screws, but of course I cannot be certain, but I do not have the Ball Nuts.

My question is this, does anyone know of a supplier near me where I can go and try a few samples out to get the correct one for this rod??

I live I Church Gresley, near Swadlincote, Derbyshire.

Can anyone advise?
