Review: As Advertised, Quality Seems Good - I was in need of some hardware to repair the cutting blade on a Black & Decker hedge trimmer. I believe the OEM hardware is SAE, but I just bought metric which is close enough to the SAE spec. I originally tried a 12 mm bolt but had to use 14 mm to ensure the threads were engaged in the nylon lock nut. I then ground off some threads with an angle grinder. This hardware works great, the only thing I wish is that it would be slightly larger, as I had to use some washers underneath.
Review: Locking nuts for steel bolts... - An absolute must for assembling steel cabinets as it locks the nuts. Happy to see these medicine-type cabinets coming back into fashion. Can be used for any thin steel assembly. Great to have around. The quality is great & there are a lot of them.

### ⭐⭐⭐⭐⭐ functional and durable
*by J***Y on July 13, 2025*

These worked well! I'm late to review these, but that just means I can say that they have been holding fine for a couple of years now. The finish was excellent and the machining certainly precise enough for my purposes.
