Square Strut Channel Washers
 |
Combine these washers with nuts, threaded rods, or bolts to hang strut channel or attach objects to it. They take the pressure off fasteners, protecting mounting surfaces and preventing damage to the channel.
304 Stainless Steel—The choice for wet and outdoor environments, these resist rust. However, they won't hold up to the harsh chemicals that 316 stainless steel can.
316 Stainless Steel—Superior to 304 stainless steel, these won't degrade when exposed to harsh weather, salt water, and most chemicals.
