Washers for Cross-Bracing
Connect cross-bracing rods or cables to structural beams. These washers have a curved top surface that lets rods pass through and be secured with a nut at different angles. The flat bottom surface sits flush against structural beams. Washers have a locking tab that keeps them in place when force is applied. They’re also known as hillside washers.

Flanged Washers for Cross-Bracing
These washers have a flange to spread force across structural beams better than standard washers for cross-bracing rods and cables. Their top surface is curved to let rods pass through and be secured with a nut at different angles. The bottom surface is flat to sit flush with structural beams. These washers have a locking tab that keeps them in place when force is applied. They’re also known as hillside washers.
Galvanized washers resist corrosion better than primed washers.

Notched Washers for Wood
Also called No. 10 Western Timber and Victor washers, these have large ODs to prevent screws from sinking into wood. The notches allow you to temporarily secure them with nails to keep them from rotating during installation.

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.
Black-oxide iron washers have a matte-black finish that prevents corrosion in dry environments.
Hot-dipped galvanized iron washers are corrosion resistant in wet environments.

High-Load Oil-Embedded Thrust Bearings
Increased iron content makes these bearings stronger and more resistant to shock loads than standard oil-embedded bearings; however they operate at lower speeds. Startup friction causes them to release a thin layer of oil on the bearing’s surface. Color is silver because of the iron.
Iron-copper bearings support heavier loads than 863 bronze 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.
