When I checked the table in Edition 26 of Machinery's Handbook, it appears that it is identical to the one he posted including the same errors. I see other discrepancies in that table such as 1.000' being equivalent to 24mm. The table he shows in his original post shows 1 1/16' to be 28mm while it is, in fact LESS than 27mm. I have been made fun of, but I do not see any serious answers from anyone here.Ģ7mm is VERY close to 1 1/16' which is exactly 26.9875 mm. Well, that does shed some light on what he is doing and what he actually needs. Pick and choose from the four answers above. You can look in published catalogs to see the various sizes that are presently being sold.ĥ. Any serious manufacturer will make an assortment of them or will lose many sales.

Tee nuts and bolts are sold with a variety of (head) sizes just because of this problem. That will probably be a good starting point.Ĥ. But if you must go ahead with this, then buy one or several of the import sets and measure the nuts. You will be much further ahead in ten years. If you are planning to make a machine or accessory and are asking such a basic question, I would suggest that you put your money into a treasury bond instead. I have about 6 or more tee nuts you can have for postage.ģ. This is what I had to do for my mill when I discovered that the tee nuts in the standard(?) 1/2' clamp set that I purchased did not fit. Just measure your machine's tee slots and buy nuts to fit. Do you plan to manufacture tee nuts and bolts?Ģ.

Do you plan to manufacture a machine or accessory with tee slots?Ĥ. Do you have a machine and want to buy tee nuts and bolts that will fit?ģ. Do you have a set of tee nuts and bolts and want to buy a machine that they will fit?Ģ.
