Will a M6 bolt fit in a 6mm hole?
Since they are bolt-nut pairs, you may be able to substitute 6mm, but the 1-1/4″ length will still be essential.
Is M6 same as 6mm?
M6 threads are 6mm metric screws. The standard metric rack screw is called M6 x 1. The ‘M’ means it’s metric. The ‘6’ is the outside diameter measured in millimeters, and the ‘1’ is the distance between adjacent threads, also in millimeters.

What is the difference between threading and tapping?
Threading and tapping are the operations used to produce screw threads. Threading is an operation in which threads are produced on the outside of a component or we can call them as external threads using a die whereas, tapping is an operation in which internal threads are produced using a tool called tap.
How big should a hole be for a bolt?
Select a drill bit 1/32 inch larger than the bolt diameter for a tight fit hole or a drill bit 1/16 inch greater than the bolt diameter for a loose fitting hole.

What is a hex screw?
Hex bolts, or hex cap screws, are large bolts with a six-sided head (hexagonal!) used to fasten wood to wood, or metal to wood.
How do you open a hex screw without a screwdriver?
Try a plastic toothbrush. Take a plastic toothbrush and lightly melt the end using a lighter or other source of heat. Once the plastic is soft you can insert it in the head of the screw and allow the plastic to harden once more. Once it is hard try to turn the screw counterclockwise to unscrew it.
Can you drill a bolt out?
When you twist the head off a bolt, break a screw shank or mangle a screw head, you have a few options: In metal, you can completely drill out a bolt and restore the damaged threads with a tap. Likewise, you can drill out a wood screw and replace it with a larger one.
What does M6 mean?
