J.W. Winco Inc. offers GN 340.1 Steel Leveling Mounts with Lag Bolt Lug, in inch and metric sizes. These RoHS-compliant leveling mounts have a base and lug of steel sheet metal, with zinc plated and blue passivated finish. The threaded stud and ISO 4032 hex nut are also zinc plated and blue passivated steel.
The hex nut is a standard part of the assembly. The rubber pad inlay is black Nitrile Butadiene rubber, 85-90 degrees Shore A hardness. The inlay is firmly embedded in the sheet metal base and secured by a screw loctited into place.
The threaded stud can be either adjusted via the internal hexagon at the top or the wrench flats at the lower end. The fixing lug anchored in the rubber inlay allows the leveling mount to be bolted to the floor.

hardness
Hardness is a measure of the resistance of a material to surface indentation or abrasion. There is no absolute scale for hardness. In order to express hardness quantitatively, each type of test has its own scale, which defines hardness. Indentation hardness obtained through static methods is measured by Brinell, Rockwell, Vickers and Knoop tests. Hardness without indentation is measured by a dynamic method, known as the Scleroscope test.
