Use these washers to evenly distribute the load under bolt or screw heads and nuts when fastening. They can also act as spacers.
Copper, brass, and silicon bronze washers are corrosion resistant in wet environments, nonmagnetic, and electrically conductive. Silicon bronze washers are stronger than copper and brass.
400 nickel washers have excellent resistance to salt water and some acids. They may be mildly magnetic.

Choose these washers for their adherence to strict military standards for material and construction.
Copper and brass washers are corrosion resistant in wet environments, nonmagnetic, and electrically conductive. Nickel copper washers (also known as Monel) are more corrosion resistant than stainless steel. They have excellent resistance to salt water and some acids.

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 loosening. 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.
Silicon Bronze washers are corrosion resistant in wet environments, nonmagnetic, and electrically conductive.
K500 nickel washers (also known as Monel) have excellent resistance to salt water and some acids. They may be mildly magnetic.
Washers that meet ASME B18.21.1 adhere to strict dimensional standards.

As a screw is tightened, these metric 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. They meet a DIN or ASME standard for split lock washer dimensions.
Standard split lock washers have a left-hand helix that have right-hand threads to prevent loosening. They have uneven split ends that bite into fasteners for a tight grip but won’t work with hardened surfaces. They hold better than curved or wave washers. These washers are not reusable after tightening.

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.

High-Temperature Dry-Running Thrust Bearings
![](/prerenderstable/mvPRE/contents/gfx/imagecache/445/4457n11-@halfx_1696516388.png?ver=imagenotfound)
Graphite provides a layer of dry lubrication that operates in high-temperature environments.
Graphalloy bearings perform at extreme temperatures and under water. They are electrically conductive and wear resistant. They’re also our highest temperature thrust bearings.
Note: Dynamic load capacity is the maximum load a bearing can withstand at a given shaft speed. If your application’s load and speed requirements are below the values listed, the bearing will work.

Extreme-Temperature Belleville Disc Springs
![](/prerenderstable/mvPRE/contents/gfx/imagecache/971/97125k51p1-d03d-digitall@halfx_636987820250687405.png?ver=imagenotfound)
These springs withstand temperatures from -400° to 1100° F. All are 718 nickel, a high-strength, corrosion-resistant alloy that's also known as Inconel. Use them on shafts, bolts, and the ends of valves to maintain tension and separate components. Unlike Belleville washers, they return to their original height once the load is removed.
Deflection is the distance a spring compresses under load. Flat load is the load at which the spring is completely compressed.
Springs may be stacked to increase working load and deflection. In a nested stack, working load is multiplied by the number of springs used, while deflection remains unchanged. In an inverted stack, deflection is multiplied by the number of springs used, while the working load remains unchanged. In a nested and inverted stack, both load and deflection are increased.

Alnico magnets aren't as strong as rare earth magnets, but they withstand the highest temperatures. Slide onto a rod or use a bolt or screw to install.
Warning: Maximum pull ratings are based on direct contact with rust-free and unpainted iron plate. Variations in material condition will significantly reduce these ratings. Do not use for lifting over people.

Medium-Pressure Inline Strainers
![](/prerenderstable/mvPRE/contents/gfx/imagecache/980/9802k31-@halfx_637571926327856344.png?ver=imagenotfound)
- Max. Pressure for Water, Oil, and Diesel Fuel: 500 psi @ 70° F
- Temp. Range: 32° to 180° F
Use these strainers in medium-pressure applications to protect sensitive equipment from damage caused by debris. The screen is in the strainer body to save space. Strainers have good corrosion resistance.
