Adhesive-Back Shim Stock
A durable acrylic adhesive keeps this shim stock from sliding out of place. Cut it into custom shapes to fit your application. Shim stock is corrosion resistant. It includes a material certificate with traceable lot number and test report.
316 stainless steel shim stock has high corrosion resistance. For precise leveling, 18-8 stainless steel shim stock is hard enough to resist scratching and deforming.
Aluminum and brass shim stock are softer than stainless steel, so they can be used as wear plates between components that rub together, preventing damage to equipment. Aluminum shim stock is lighter than brass. Brass shim stock is more corrosion resistant than aluminum.
Copper shim stock is a good conductor of heat and electricity, so it’s often used when installing heat sinks.

Split Lock Washers for Socket Head Screws
Also known as high-collar lock washers, these have smaller outside diameters than standard split lock washers to fit neatly under socket head cap screws. As a screw is tightened, they flatten to add tension to the joint and prevent loosening from small amounts of vibration.
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.
316 stainless steel washers have excellent resistance to chemicals and salt water. They may be mildly magnetic.
Washers that meet ASME B18.21.1 adhere to strict dimensional standards. Steel washers also meet standards for material properties.

Triple-Wave Washers
With three points of surface contact, these washers provide more stability than single-wave washers. They are curved and flexible to act like springs, compensating for tolerance variations and uneven surfaces. You can also use them to damp vibration.
