  • 1/2 13 Unc Flange Nut

    Also called TEC-41605

    spare nuts for Bridgeport clamping kit

    any sources cheap in the UK

    all i can find is seller on ebay that want £9.80 for 6..free postage ..but for chinese things seem still high

    or j£l industrial who want £1.20 each..and would be a special order from the USA

    HMM when i don't want to pay that
    I would rather order something over 20 and get a deal.as i seem to loose them all the time .

    Yes , i can get ordinary nuts by the bucket load ...but these flange nuts are meant for the job..thicker walled ..large flange ..hardened.

    No, I can't help with a supplier. But the nut you seek is a DIN 6331 nut, maybe that will help?

        You might try Travers Tool Co www.travers.com but the shipping charges will probably be prohibitive.

        Or you could make a flanged nut yourself out of whatever you have that is equivalent to 1144 or 4140 or similar. The only slightly difficult part is indexing to get the hex.

          Get some M12 & run a tap through them? The cheap ones are probably not hardened.

            What Tim said! I do it all the time, beats paying a fortune. I have a bucket full of M12 flange nuts leftover from my shed.

                This is the only one i can find

                http://www.ebay.co.uk/itm/25-M12-1-7...item1c154d391c

                I've phoned up three UK companies ..the only ones that have them ..one wants £36 when i order 24 of them ..they are unc

                another with...12mm ones want £1.20 each plus vat plus postage..that would turn them into £2 each

                how is it that, these milling clamping kits are made in china/Taiwan ..

                yet no one sells any spare bits and pieces for them.

                          It's $13.25 US to ship a small flat rate box from US to UK. It will take about 30 1/2" flange nuts. Here flange nuts cost about $1 each for import and $2.30 for domestic. Shipping cost per nut is in inverse proportion to the number shipped.

                          Maybe someone on this side of the pond will as a compensated favor buy them and ship to you.

                          Flange nuts are easy to make If you have one of those 5C collet block square and hex thingies to hex them on. Or an indexer.

                          http://business.shop.ebay.com/i.html...k&_sacat=12576

                          Maybe put that in the box too.

                          I've made about a jillion flange nuts and T nuts out of mild steel. I machine them, run them up to red heat , and quench them in cold water. Mild steel doesn't harden much but it will get a tough skin with a cold water quench. I don't draw the temper of mild steel at all. I use them as quenched. They hold up pretty well. Case hardened or alloy steel is better of course but that's more money.

                          And no, you don't want the nuts in the upper part of the Mc Master Carr linked above. Note it says "distorted thread". Great for aircraft when you want things to stay put. Not so good on machine tools where you change the set up a dozen times a day. Get the ones towards the bottom third of the linked page where it rerfers to "flange nuts for clamping" and goes on to explain how they are sometimes called collar nuts.

                              Just an easy example of a hardened flange nut. McMaster is always the most expensive. If I didn't have a bunch, I'd amble down to my local screw store...
