About half the strength of medium-strength bolts, these Grade 2 bolts are for light duty fastening. These bolts are commonly used in tight spaces with moving parts, such as grain elevators and other belting systems, because the smooth, low-profile head provides a flush fit when installed.
Definitions
Alloy Steel: A ferrous (or iron-based) alloy that contains appreciable concentrations of alloying elements (other than C and residual amounts of Mn, Si, S and P). These alloying elements are usually added to improve mechanical and corrosion resistance properties.

What size spanner fits a M10 bolt?
A 17mm spanner therefore fits a nut 17mm across its flats and this is normally a nut to fit a 10mm diameter bolt (M10). Also, hexagonal key sizes are given as the distance across their flats and so a M10 Allen Screw for example would need a 8mm key to fit it.
What does the M before a number mean?
The M before a number stands for metric. The next number is the diameter size. For example, M8 is a metric screw and has a diameter of 8mm.
