M6 screw and bolt sizes for the more common ones we deal with. This will give information about the maximum screw head heights and head diameters as well as the driver size needed to install or remove them. If unfamiliar with DIN and ISO numbers, they can be thought of as exact fastener names for each specific screw and are usually given as either DIN or ISO (eg. DIN 912 or ISO 7380).

Is M6 screw 1 4 inch? ›
You can identify an M6 screw by measuring the diameter with a ruler. It'll be 6 mm, or slightly more than 7/32 inches (0.228″).
What is the difference between M6 and M8 bolts? ›
If the thread is specified simply as M6, it's a standard pitch. Standard pitch would be fully written as M6 x 1.0. Fine would be M6 x 0.8. Note, though, that the pitch varies with the thread diameter – so a standard M8 thread is M8 x 1.25 and a fine thread M8 x 1.0.

How do you measure a M6 bolt? ›
Metric Bolt Lengths
Socket head, pan head, button head and hex head bolts are measured from the underside of the bolt head to the end of the shaft. For flat head bolts, the length includes the bolt head height and for dome head bolts the length is measured from the thickest, highest point on the curved head.
Does M6 bolt mean 6mm? ›
M6 Bolt Dimensions
M6 refers to the diameter of the bolts shank. M6 meaning 6mm. All our bolts are a metric coarse thread, the M6 range have a 1.00 pitch thread profile.

Does an M6 nut fit an M6 bolt? ›
does it go by the diameter of the bolt shaft or the size of the head or the length of the bolt? and will an M12 nut and washer fit an M12 bolt? M6 bolt is about 6mm in diameter, M8 about 8mm etc. M6 nuts fit m6 bolts. M6 washers will fit over an m6 bolt so a bit bigger than 6mm.

What is the closest imperial bolt to the M6? ›
If you can get an M6 screw or bolt in and it's a rattly fit then the closest is 0BA. A 1/4 Whit would not screw in as the thread pitch is wrong. Whit is very coarse, whereas M6 and 0BA both share a 1mm thread pitch.
What does the M stand for in bolts? ›
Taking a closer look at this description, let's explore its meaning: M = This designates the fastener is a metric size. 10 = The nominal diameter in millimeters. 1.0 = The thread pitch, or distance between threads, in millimeters. 20 = The fastener's length, in millimeters.
How do I figure out what size bolt I need? ›
To determine bolt diameter, measure the distance from the outer thread on one side to the outer thread on the other side. This is called major diameter. Alternatively, you can measure the bolt shank diameter. The shank is known as the body or sometimes, the shoulder.
How to find the right nut for a bolt? ›
Measure the distance between threads in millimeters to determine the thread pitch. Take both versions of these measurements to a local hardware store; you can then identify the fasteners with the closest measurements to yours. For more accurate measurements, consider investing in inch and metric thread gauges.

Is M6 the same as 1/4? ›
A normal M6 screw is a rattly fit in a 1/4 BSF full nut. You can make M6 work if you don't muller it too hard with the spanner. It can't be a 1/4 Whit because they are only 20 TPI and that won't take an M6 at 25 TPI.
