General Purpose Washers

Your go-to metal washer for every screw size. Washers take the pressure off nuts and screws to protect mounting surfaces.

Steel

Corrosion-Resistant Chrome-Plated Steel—The brightest, shiniest finish we offer, this plating has a mirror-like appearance that is often used in decorative applications. It resists salt water and chemicals better than zinc plating and is less likely to wear off.

SAE Washers

Originally designed for the automotive industry, these washers conform to SAE sizing standards. They generally have smaller diameters than USS washers to fit in cramped spots and are thinner to create more precise gaps. Washers distribute pressure under screws and nuts to protect your mounting surface.

Encased Neodymium Disc Magnets


1	2

Powerful performance with built-in durability. A protective case shields these magnets from the elements as well as cracks and chips when handling, mounting, or sweeping them. With the highest strength-to-size ratio of any magnet, these deliver powerful pull force even in tight spaces.

Warning: Maximum pull ratings are based on direct contact with rust-free, unpainted iron surfaces. Variations in material condition will significantly reduce these ratings. Do not use for lifting over people.

USS Washers

These washers meet USS sizing specifications and typically have larger diameters than SAE washers. As a result, they accommodate larger screws and nuts and distribute pressure across a wider surface area. They are also thicker, so they withstand heavier loads and span wider gaps when used as spacers.

Encased Ceramic Disc Magnets

Our most economical magnets with built-in durability. A protective case shields them from cracks and chips caused by bumps and drops. Ceramic magnets deliver a cost-effective balance of corrosion and temperature resistance. However, they are not as strong as rare earth magnets.

Warning: Maximum pull ratings are based on direct contact with rust-free, unpainted iron surfaces. Variations in material condition will significantly reduce holding strength. Do not use for lifting over people.

Nonmarring Encased Neodymium Disc Magnets

These safeguarded magnets grip surfaces without marking them. The rubber-coated case protects metal housings and control panels from scratches and adds friction for a tight grip. It also shields the magnet from cracks and chips caused by drops and bumps. With the highest strength-to-size ratio of any magnet, these deliver powerful pull force even in tight spaces.

Warning: Maximum pull ratings are based on direct contact with rust-free, unpainted iron plate. Variations in material condition will significantly reduce these ratings. Do not use for lifting over people.
