Start by finding your Bolt Size.
Then determine the Inner Diameter (ID) and the Outer Diameter (OD) as well as your Thickness needed for your project.
Washers are multipurpose fasteners that are vital in a variety of applications. In general, washers have two main functions: to distribute the pressure of the nut evenly over a surface without damage and to ensure that the nut is pressed against a smooth surface to reduce the chances of loosening over time. Ensure a tighter join with a lock washer, or pre-load it with a wave washer.
Shims can be used to incorporate spacing and clearance in all manner of applications. They can be use as a temporary solution or as a permanent component in many different settings. We offer standard and custom shims in a variety of materials, and in a comprehensive range of sizes and shapes.
AMPG has thousands of hard to find items, made in the USA. We specialize in non standard sizes – extra thick or extra thin. Also small quantities of traceable Military Specification washers. We manufacture a full line of machined product – countersunk washers, spherical washer sets, and others. We have a large line of square washers in many materials, in 2”, 3” and 4” square.
