304 Stainless Steel Square Washers for Unistrut, 1/4" - 5/16" Hole, 1-5/8" x 1-5/8" (Lot of 48)

These 304 stainless steel square washers are designed specifically for use with Unistrut metal framing systems, providing secure and stable connections for bolts ranging from 1/4" to 5/16". The square shape fits perfectly into Unistrut channels, preventing rotation and ensuring even load distribution during installation. Constructed from corrosion-resistant T-304 stainless steel, they offer excellent durability in harsh environments, including outdoor, marine, or chemical exposure settings, where rust and degradation are concerns. Key applications include construction, electrical conduit support, HVAC installations, and mechanical assemblies. Advantages over standard carbon steel washers include superior corrosion resistance, longer lifespan, and maintained strength in high-moisture or acidic conditions, though they come at a higher cost and may be overkill for dry, indoor use. Drawbacks are minimal but include higher weight compared to aluminum alternatives. Based on attached images, this lot of 48 washers appears to be in new or like-new condition, with no visible wear, scratches, or damage; they are packaged in a plastic bag. No serial numbers or faceplates are present, and there are no attached parent/child assets like sensors. For technical details, refer to Unistrut's general accessory guides (e.g., Unistrut Engineering Catalog PDF available at https://unistrut.com/resources/catalogs). Estimated market price is based on comparable online listings for similar stainless steel Unistrut washers.
