          Here's the dimensions of mine (metric), also those of the 27mm long T-nuts I use on the mill.

            How does a 14.25 wide nut fit in a 13.5 wide slot Dave ?

                Someone who cannot be named for legal reasons screwed up the drawing, dimensioned it, and then failed to check it still made sense. You may think it was me who blundered, I could not possibly comment.

                The slot is 13.8mm wide, and the T-nut 13.5

                Apologies all round and many thanks to Nigel in Quality Control!

                  Ok, trying to not sound thick but are you saying buy 14mm T nuts, which are actually 13.5mm??

                    Here you go-

                    tee slot.jpg

                    So you need 'T' Nuts to the Dims of item 9524 above. Only come with 12mm threaded stud holes.

                    Regards

                        My VMC has the same 14mm Nom slot width.

                        If you are thinking of a new clamp set then a little food for thought:

                        I bought the standard 14mm x M12 clamp set available for this T slot size.

                        IMO after using it for a while I found it overkill and rather clumsy ( big clamps etc ) for the table size, so I opted to buy the next size down M10 clamp kit and made 6 x new 14mm x M10 T-Nuts. I find this more suited for my needs and more a balanced/matched set for this size of table and machine size.

                        I have kept the first clamp set per chance it was needed and it has been just a couple of times, but only because I needed some addition studs and clamps for a double setup i had on the table.

                          Thats interesting, so each size up, 10mm, 12mm, 14, means all the pieces of the set also increase in size?

                            Out of interest if I got the 10mm stud kit instead of a T Nut could I not just buy some 25×12 flat bar to make locating nuts

                              Hi Petro,

                              Yes you could use flat strip 12mm thick but not an ideal way of doing it. My T nuts are stopped about a thread short of going right through the T nuts. Deliberatly done to stop the studs going through and locking the T nut by way of the end of the stud.

                              If you use 12 mm strip doing this would only leave about 11mm of effective thread grip. The ideal amount of thread hold for any sort of clamping forces or stressed items is a minimum of 1.5 x thread/stud diameter so for M10 you ideally need 15mm minimum. T nuts are an ideal simple milling project for a MW18. Blacked in oil look OEM as well.

                                  I have home made M6 and M8 t-nuts for my X2 mill as the standard M10 fixings are too clumsy for some things.
