    • Heavy duty washers with durable coating!

Why did you pick this product vs others?: I got these because I needed some black washers to match the black bolts I used on my pergola. Washer quality: These are well- machined, very heavy duty washers with complete black coating and a nice thick gauge steel construction. Look: I was happy and a little surprised that the coating didn’t scratch off when it was subjected to tool work, including an impact socket! Value for money: Very happy with these, and I think they’re very good quality for the money! ... show more

    • Too heavy for making chainmail armour (armor)
Size: 1/4" (100 pack)
I wanted to try these for a niche use - making chainmail, using half of these washers and half riveted rings. However, these are too heavy for that. Nothing wrong with them. The black coating helps prevent rust but does not mitigate it entirely.

    • Usable steel utility washers
Size: 1/2" (25 pack)
Review Image by vtam
These washers are serviceable utility type. Thickness is .092", OD is 1.375", ID is .602". They are stamped steel (not stainless). Not sure what to make of the finish, which is brownish black and fairly rough and uneven. See photo of back and front. I'm guessing maybe it's a heated oil finish. No idea how well it will last in damp environment. They call it a "Rustpert" finish. ... show more

    • Consistently made and coated
Size: 5/16" (100 pack)
All the washers (I got the 5/16"x7/8") are consistently and cleanly made. No rough edges, flashing etc. As far as the Ruspert coating, I'll need to expose them to the elements over time. The top black coating will scratch off somewhat easily, but as I understand it there are other coatings/layers underneath that make up the finish so the protection is likely still there. ... show more

    • As Described
Size: 5/16" (100 pack)
It's a bag of washers. They are true to size and seem uniform in construction. They will be handy for many projects.
