Besides missing 3 of 8, they're clearly zinc coated and not galvanized. It says galvanized on the label, but I know they're clearly not.

I keep these on my shelf for all kinds of crafts and fabrication. Aside of the most common use of joining two threaded rods together they have their place for me when I build jigs in my wood shop. I also may need a handle for a tool and these are a good solution. I have also used them as stand offs.Cheers

Product Reviewed: 30 Packs 3/8''-16 Coarse Coupling Nuts, Hex Coupling Nut for $16TL;DR; It’s a coupler nut?I use these mostly for threaded inserts on shop made handles as 3/8” is a fit for most of my gear. I cut them in 1/3 or 1/2 depending on the application and also use them as lathe arbors.These are pretty standard looking nuts and are fully threaded and galvanized per the description.Nothing to dislike here and the description is a match. The value is very good compared to others I’ve tried if you need an inventory.5StarsHow I review:Reviews start with 5 stars and I subtract points.- 0 for value but I try to provide guidance-0.5 to -3 for product not matching description e.g. stainless steel is actually plated steel-0.5 to -3 for product missing badly on executionI select products carefully so low (1-3 scores) are rare but detailed comments and critiques almost always are in the review. Most of my reviews come out 4-5 range.If possible I dismantle or destroy items to examine inner workings.

These are great coupling nuts, with the quality being just as good as ones I have bought from large companies who specialize in hardware sales. I've used quite a few of them on various projects and have had absolutely no issues. Would definitely not hesitate to buy more when these run out.

Coupling nuts are a great thing to have around if you work with threaded rods.I got these coupling nuts to round out my set of coupling nuts.They are well made and work as described.When it comes to parts like these, they either work or not.These coupling nuts work just fine.And are a good deal for the amount of product you get vs. the price.
