Shim Stock
Cut it into custom shapes to fit your application.
For accurate leveling, choose materials such as steel or stainless steel, which are hard enough to resist scratching and deforming. Softer shims, like copper or aluminum, can be used as wear plates between components that rub together, preventing damage to equipment. Metal shims include a material certificate with traceable lot number. Most shims include a test report.
Spring steel shim stock is comparable in strength to carbon steel shim stock, but is harder and holds its shape better. It isn't as corrosion resistant as other shims.

Peel-Away Layered Shim Stock
Cut this shim stock it into custom shapes to fit your application. Stock is made of layers of material bonded with adhesive; remove layers with a utility knife until you get the thickness you need. To make the layers easier to pull apart, gently heat the shim to soften the adhesive.

Split Lock Washers
As a screw is tightened, these washers flatten to add tension to the joint, counteracting fatigue around the joint from small amounts of vibration. This makes them a common choice to prevent fasteners from loosening. However, they resist the least amount of vibration compared to other locking washers.
These washers are compatible with fasteners that have right-hand threads to prevent clockwise rotation. The uneven split ends bite into fasteners for a tight grip, but they won’t work with hardened surfaces. These washers hold better than curved or wave washers. They are not reusable after tightening.
Black-oxide steel washers are mildly corrosion resistant in dry environments.
316 stainless steel washers have excellent resistance to chemicals and salt water. They may be mildly magnetic.
18-8 stainless steel washers have good chemical resistance and may be mildly magnetic.
Zinc- and zinc yellow-chromate plated steel washers are corrosion resistant in wet environments.
Hot-dipped galvanized steel washers are 10 times as corrosion resistant as zinc- and zinc yellow-chromate plated washers.
Zinc-flake-coated steel washers are 40 times as corrosion resistant as zinc-plated washers and comparable to Magni-coated washers.
Aluminum washers are lightweight and corrosion resistant in wet environments.
Bronze washers are corrosion resistant in wet environments, nonmagnetic, and electrically conductive.
Washers that meet ASME B18.21.1 adhere to strict dimensional standards. Steel washers also meet standards for material properties.

Oversized Split Lock Washers
Compared to standard split lock washers, these are thicker and have larger outside diameters. As the screw is tightened, these washers flatten to add tension to the joint. They counteract fatigue around the joint caused by small amounts of vibration, making them a popular choice for preventing fasteners from loosening. However, they resist the least amount of vibration compared to other locking washers.
These washers match with fasteners that have right-hand threads to prevent clockwise rotation. The uneven split ends bite into fasteners for a tight grip but won’t work with hardened surfaces. They hold better than curved or wave washers. They’re not reusable after tightening.
All washers adhere to strict ASME dimensional standards. Steel washers also meet the standard for material properties.
