Ring Shims
Precisely align, level, and adjust spacing on fasteners, shafts, and machinery with these shims.
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.
Carbon steel shims have excellent strength and can be welded, but aren't as corrosion resistant as other shims.

Tight-Fit Ring Shims
For a snug fit around a shaft, the ID of these shims is held to a tighter tolerance than other ring shims.
For accurate leveling, choose materials such as steel or stainless steel, which are hard enough to resist scratching and deforming. Softer shims, like brass, can be used as wear plates between components that rub together, preventing damage to equipment.
Alloy steel shims are stronger and harder than stainless steel and brass shims, but they aren’t as corrosion resistant.

Shim Stock
Cut it into custom shapes to fit your application. Sheets come flat packed.
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.
PTFE plastic shim stock is slippery, so it can be used to reduce friction between parts. It also has excellent chemical resistance.

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.
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.

Electrical-Insulating Sleeve Washers
Also known as shoulder or insulator washers, these nonmetal washers block electrical current and prevent galvanic corrosion from mating different types of metal.
Nylon 6/6 washers have good abrasion resistance. Exposure to moisture may cause them to expand.

Split Lock Washers for Socket Head Screws
Also known as high-collar lock washers, these have a smaller outside diameter than standard split lock washers to fit neatly under socket head cap screws. As the screw is tightened, these washers flatten to add tension to the joint. This counteracts fatigue around the joint from small amounts of vibration, making these washers a common choice to prevent fasteners from loosening. However, compared to other locking washers, they resist the least amount of vibration.
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.
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. Black-oxide 18-8 stainless steel washers have a matte black finish.
Black-oxide steel washers are mildly corrosion resistant in dry environments. Zinc-plated steel washers are corrosion resistant in wet environments.
Washers that meet ASME B18.21.1 adhere to strict dimensional standards. Steel washers also meet standards for material properties.
