Review on SNUG Fasteners SNG586: High-Quality 1/4-20 Stainless Steel Nylon Insert Hex Lock Nuts - Pack of 50 by Richard Counts

If you need a nut for attachment, use a nylon insert nut. If you want a nut that doesn't wobble, use stainless steel. These SNUG nuts combine the best of both worlds. The nylon insert is slightly smaller than the nut and grips the bolt, while the stainless steel ensures they stay rust-free. These nuts are good quality with a clean finish. Nice plastic storage container that really looks like it will last a while. highlighted.
