What does a triangle on the head of a bolt mean?
Re: Triangle sign on bolt head The Triangle means it is a Close Tolerance bolt .
What is M bolt size?
The “M” designation for metric screws indicates the nominal outer diameter of the screw thread, in millimetres (e.g., an M6 screw has a nominal outer diameter of 6 millimetres).
How do I know what size drill bit to use?
How to Choose Drill Bits by SizeUse a bit 1/64” smaller than the target hole size for softwoods.Use a bit exactly the same size as the hole when working on other materials.If you’re not sure which to select, choose a drill bit 1/64” larger than the hole you wish to create.
What does m8 1.25 bolt mean?
For metric fasteners, you will see a M8 x 1.25 or an M8 x 1. For thread pitch, the distance between two points is the second number meaning the higher the number the fewer threads there are. This means the M8 x 1.25 is the coarse threading and the M8 x 1 is the fine thread.
What does M mean on a bolt head?
The M here refers to the metric system. So sizes are in metric, as opposed to the standard system (aka the US system). All nuts and bolts come in sizes that are expressed either in the metric or the standard system. 5m does translate to a diameter of 5mm.

What are standard bolt sizes?
Typically, machine bolt sizes range from 1/4″ to 1 1/4″ for square heads and 3/8″ to 1 3/4″ in diameter for hex heads, and lengths span from about 3/4″ to 18″ for square and 6 1/2″ to 24″ for hex heads. Measure length from under the head to the threaded end of the bolt. Both square and hex heads are available.
What do bolt sizes mean?
The size of a metric screw or bolt is specified as diameter, pitch and length, in millimeters (millimeters is abbreviated “mm”). For nuts, size will appear as diameter and pitch. … In the example above, a pitch of 1.0 means that from one thread to the next thread, the distance is 1.0 millimeter.

How do you determine bolt size?
To measure the diameter of screws and bolts, you measure the distance from the outer thread on one side to the outer thread on the other side. This is called the major diameter and will usually be the proper size of the bolt.
What does 3 lines on bolt head mean?
Three radial lines will indicate an SAE grade 5 fastener, while six radial lines will indicate an SAE grade 8 fastener. These are the most common grades, but there are others.
