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.

Use a single shim on feet or positioning arms that are secured with multiple fasteners. The slots let you insert, remove, and adjust the shims without disassembling your machinery. Shims are made of steel for good strength. Also known as finger shims.

As you tighten a bolt, these metric washers flatten to add tension to the threaded joint and prevent loosening from small amounts of vibration. All of these washers meet a DIN or ASME standard for split lock washer dimensions.

Curved and wave split lock washers can be used with bolts that have right- or left-hand threads to prevent clockwise or counterclockwise rotation from vibration. Although they don’t grip as tight as standard split lock washers for applications with clockwise rotation, they are best for those with counterclockwise rotation. These washers retain their shape when untightened and will not damage nuts and bolts, so all can be reused.

Steel washers are stronger and more wear resistant than zinc-plated steel and stainless steel. Use them in dry environments because they will rust in wet and corrosive environments.

Designed for use with bearing nuts, these lock washers have a conical shape that presses like a spring against bearings, bushings, gears, and pulleys to hold them in place on your threaded shaft or spindle. They also have an inner tab that sits in the shaft or spindle’s keyway to prevent the nut from loosening. Made of steel, they’re strong and flexible.

Spring lock washers with external teeth grip components using their teeth, in addition to spring tension.

DIN 462 and DIN 5406 washers meet international standards for lock washer dimensions. Pair DIN 462 washers with DIN 1804 bearing nuts, and DIN 5406 washers with DIN 981 bearing nuts.

Bend the tab of these metric lock washers against the flats of a hex nut or bolt head to prevent the fastener and washer from turning and loosening due to vibration, wear, or changes in temperature. Their partial cone shape gives these washers spring-like flexibility, so they distribute force and grip tighter than split and tooth lock washers. All meet DIN 432, an international standard for tab washer dimensions.

Steel washers resist wear better than 316 stainless steel, but aren’t as corrosion resistant.

316 stainless steel washers are more corrosion resistant than steel, and nearly as strong. You can expose them to salt water, chlorine solutions, and chemicals without any rusting.
