Also known as shoulder washers.
As you tighten your screw, the rolled collar compresses under the head to create an insulating barrier between a screw shank and a mating surface.
These washers have a flat bottom and high walls to protect metal screw heads from electrical current.
Reinforce holes in soft material to keep them from collapsing around screws.
Use on clamps with open arms to keep the holding screw in place.
Use the angled edges to hold and align tie-down straps.
Flat and oval head screws sit flush within these washers for a neat, finished appearance.
Cover oversized holes and the ends of tubes and pipe with these cup-shaped washers.
Repair sagging, cracked plaster with these washers. The holes allow plaster to flow through to form a secure bond between the washer and the wall.
Steel washers provide a stronger bearing surface than plastic washers
Plastic washers resist moisture, chemicals, and friction and are good electrical insulators.
These washers have a flange to spread force across structural beams better than standard washers for cross-bracing rods and cables.
These washers have prongs that pierce foam insulation so they stay in place.
A square hole prevents these washers from turning with the bolt or shaft.
Able to withstand pressure greater than 2,000 psi, these one-piece bonded washers create the tightest seals.
Able to withstand pressure greater than 3,000 psi, these one-piece bonded washers create the tightest seals.
These washers are rated to withstand pressure up to 100 psi.
Also known as thread-sealing washers, use these under nuts and other washers.
Create a stronger seal than metal or rubber alone. These one-piece washers are metal for strength with a bonded rubber seal that creates a tight grip.
Mount components to your enclosure without worrying about leaks.
Eliminate cavities under screw heads where contamination may occur.
Designed for use with square-neck bolts such as carriage bolts, these washers have teeth that dig into wood and other soft material to prevent rotation.
Also known as shoulder and insulator washers, these nonmetal washers block electrical current and prevent corrosion from mating different types of metal.
Keep pipe flange connections sealed during demanding applications. When installed under flange bolt heads, these springs compensate for shock loads, vibration, and thermal expansion and contraction.
Reduce the knockout size in an outlet box or enclosure so you can attach a different size of conduit to it.
Seal out moisture while reducing the knockout size in an outlet box or enclosure so you can attach a different size of conduit to it.
