M3 Bolt Dimensions

M3 Bolt Dimensions M3 x 4 M Metric Major Diameter in MM x 4 MM between threads So M3 x 4 is 3 5mm diamter with 4mm per thread so about 25 threads per CM Most metric screws

I find the difference between dimensions M N and R S to be mysterious and suspect that the answer to my quandary is hidden therein My guess is that this is an M4 since the I m going to be building a workbench so I ve been screw shopping I need some explanation on the sizing of screws when they are advertised as example 6 x 3 4

Well there s M3 5 x 0 6 and M3 5 x 0 35 but neither is all that close to 32 TPI 42 3 72 5 TPI respectively 0 8mm is close enough to 32 TPI to be confusable at 31 75 TPI but The size quoted is the size of the bolt that would be used with it the same as a normal nut so an M8 rivnut would be used with an M8 8mm metric bolt In the example in your picture a 1 4

M3 has a thread pitch of 0 5mm and M6 and M7 have a thread pitch of 1mm so the math works out nicely for those sizes For other sizes though it results in an oddball size If M3 5 is rare but common in British and some European electrical hardware usually slotted e g it holds our sockets and light switches to the back boxes I have seen

AndrewMorton to be fair I did hide all that under the word conveniently The reason I want the metal cheap despite also shelling out for a more expensive tap and die set Bolt stuck in a hole When the bolt is heated it expands Since the shaft of the bolt is constrained it can t expand inside the hole The bolt expands in the direction of the green
