Review on White Nylon Insert Marine Stainless by Firman Harrington

I am remodeling my boat and wanted these nuts first because they are marine grade stainless steel. I like that they have a nylon lock nut insert to keep them from loosening, although there are some problems tightening the nuts on the bolts against resistance when you need to reach the gunwale to attach it, for example. I used a small, long-necked socket wrench to hold the nut securely while I screwed the bolt in with my other hand. The result is worth it - the bolt does not hang out. I put these nuts on these marine grade #8 bolts and they thread correctly into the B08J9VC5CM. However, note that you get 50 nuts per pack and 100 screws/bolts.
