Metric Leveling Washers for I-Beams
Mounted on an I-Beam
Commonly called beveled washers, these metric washers are tapered to fit inside an I-beam's flange to provide a parallel bearing surface.
Zinc-plated steel washers are coated for corrosion resistance in wet environments.
Hot-dipped galvanized steel washers are ten times more corrosion resistant than zinc-plated washers.
18-8 stainless steel washers are the most corrosion-resistant option.

Leveling Washers for U-Channels
Tapered to fit in a U-channel, these washers create a parallel bearing surface. They have a zinc-plated finish, so they resist corrosion in wet environments.

Wedge Lock Washers
These two-piece washers provide more locking power than split, tooth, and spring lock washers. Wedges on the inside lock the two pieces together, and serrations on the exterior grip surfaces to resist loosening from high vibration and shifting. Washers are reusable.
316 stainless steel washers have excellent resistance to chemicals and salt water. They may be mildly magnetic.
Zinc-flake-coated steel washers are corrosion resistant in wet environments.
316 stainless steel and zinc-flake-coated steel washers are comparable to NORD-LOCK® Series washers.
Black zinc-flake-coated steel washers are comparable to Sherex TEC Series washers.
Spring lock washers are comparable to NORD-LOCK® X-Series washers. They withstand vibration better than standard wedge lock washers by combining the locking power of a wedge lock with the clamping force of a spring lock.
