Slotted Square Plate Washers

Slotted hole square plate washers allow for adjustability for bolts that are not in the middle of the plate. They are available in plain or hot dipped galvanized for additional corrosion protection in harsh environments.

Square Beveled Washers – Hardened and Malleable

Square beveled washers are most commonly used when you have two unparallel surfaces that need to be bolted together, such as fastening bolts through the flanges of I-beams in structural applications. The type of beveled washer required depends on the material of the bolt being used. For instance, when A490 or A325 are required, you will need to use hardened beveled washers (F436). Malleable beveled washers are suitable for most other applications.

Square Plate Washers

Designed to limit stress on contacting parts, square washers are useful for reducing noise, vibration and electrical current. Required in many building codes, square plate washers are more effective in creating a good friction connection between the sill plate and the anchor bolt.
