Review on 🔒 SNUG Fasteners SNG587 50-Pack 5/16-18 Stainless Steel Nylon Insert Hex Lock Nuts - Durable and Reliable Fastening Solution by Jeremy Hahn

You can buy similar stainless steel nuts with nylon inserts for $1.18 each or a pack of 10 for $6.06. For the math it would cost $59.00 to buy this 50 pack separately which costs $8.65 or if you choose 10 packs it costs $30.30 for 50. Obviously that's a great deal. I've never needed 50 at once, but I need them regularly and I like to have a few extras so I don't have to run to the store every time I need a pair. The stainless steel feature makes these nuts the perfect choice for anything that will be exposed to moisture or used outdoors. The nylon insert ensures that the nut does not loosen due to vibration. Excellent purchase. You will not be disappointed.
