Slotted Shims
The slot lets you insert, remove, and adjust the shims without disassembling your machinery, while the tab keeps fingers and tools away from machine feet. Use an insertion tool (sold separately) for better leverage and reach. Shims are etched with the thickness.
18-8 stainless steel shims have a balance of strength and corrosion resistance.

Large-Adjustment Slotted Shims
Use these thick shims to align cabinets, doors, and windows, or for other rough leveling. They're color-coded by thickness for easy identification. The slot makes it easy to insert, remove, and adjust the shims. Shims are made of plastic to resist moisture and prevent rot.

Color-Coded Horseshoe Shims
These shims are color-coded by thickness for easy identification. The horseshoe design fits around screws. Use them to align cabinets, doors, and windows. Shims are made of plastic to resist moisture and prevent rot.

Breakaway Shim Plates
These thick shims are scored to make size adjustments easy—break off the excess shim for a custom fit around fasteners or corners. Unlike wood shims, these plastic shims resist moisture and won’t rot. Use them to align cabinets, doors, and windows, or for other rough leveling.

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.
Washers that meet ASME B18.21.1 adhere to strict dimensional standards. Steel washers also meet standards for material properties.

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.

Leveling Washers for I-Beams
Commonly called beveled washers, these are tapered to fit inside an I-beam's flange to provide a parallel bearing surface.
