A leveling screw is a height-adjusting bolt used in machining operations, also known as a leveling bolt. In addition, level adjustment screws that are attached to the feet of equipment and shelves and used for leveling are sometimes called adjusters or adjuster feet.
In both cases, locknuts or spherical washers are generally used to prevent misalignment after the horizontal position is established. By using these between the bolt and the object to be fixed, it is possible to avoid loosening of the bolt and uneven contact of the nut during installation.
Uses of leveling screws are to adjust the height of workpieces, machinery, and equipment to make sure they are horizontally level.
When used for horizontal adjustment of machinery or for level adjustment when installing a unit on a stand, usually a level adjustment screw and a device or unit for leveling are attached to the bolt installed on the fixed base, and the adjustment screw is tightened. In this case, a wrench is usually used to rotate and adjust, so it has a hexagonal head or body.
The use of adjuster feet is also very wide-ranging, and they are used in a variety of machinery and fixtures.
When selecting leveling screws, you should consider not only the size and shape of the basic screw part, load capacity, and corrosion resistance, but also the design of the adjuster foot and its function such as angle adjustment.
Screw size is also directly related to load capacity, so it must be checked in conjunction with the shape of the equipment. The material of the screw has a great deal to do with corrosion resistance as well as load bearing capacity.
In cases where food machinery or corrosive chemicals are used, it is common to use materials that match the equipment, etc., or to use products made of stainless steel, which has excellent corrosion resistance.
When used for horizontal adjustment of machinery or units, it is usually installed on a nearly horizontal pedestal, so angle adjustment is not required. If so, it can be absorbed.
When used as an adjuster foot, a level adjustment screw with an angle adjustment function is required, especially when installing on a sloping floor.
