Sturdy Hold for Home Renovations

When I tried this product, I was pleasantly surprised by the incredible hold it provided. I used it for some DIY home renovation projects and it held up incredibly well. The black oxide coating provides an added layer of protection against rust and the nylon insert made it easy to tighten without losing grip. The only downside was the price, which may be a bit steep for those on a budget. Overall, a great addition to any tools and home improvement kit.

Pros
  • Durable and long-lasting with its black oxide finish
Cons
  • Sometimes the nylon insert can cause difficulty in tightening the screw properly

White Inserts on Black Nuts

White nylon lock that negates the purchase of anodized black lock nuts. You can find black on black. Much more attractive

Pros
  • Industry and Science
Cons
  • Functionality

Rusts best in nuts

They were installed in a damp location, not wet and rusted within 1 day. Came back and was disappointed. I understand it was steel/black oxide, not stainless steel/black oxide, but the black oxide should have helped prevent rust for at least a day or more.

Pros
  • Locknuts
Cons
  • Mostly good but...
