Surprising How Handy This Is!

One of the biggest mysteries of my garage screw/bolt/nut collection is that I never know exactly what I have and what I need. I've never had a thread and bolt size checker. This is perfect. The pieces are removable, so you can check your bold or nut size on your project rather than having to remove them. This works particularly well when you are looking for a nut for a hard-to-reach bolt. This lets you quickly size the bolt in the hard-to-reach spot, and then you can turn around and size the correct nut for the bolt. Brilliant! The kit comes in a nice case with everything clearly labeled. It includes metric and imperial sizes. I am actually looking forward to organizing my nuts and bolts this winter.

Very handy

Works exactly as it should. From what I can tell, they seem to be accurate. Very handy to have around. Case is a little cheap feeling but works just fine for storing.

These gauges are more handy than you can imagine!

I already had a set of thread gauges when I ordered these. The reason I wanted another set was because they are just so incredibly handy that I wanted a set in my basement workshop in addition to the garage. I literally need these things in every work area.

My first set is the "gauges on a wire" type, and this set looked to be easier to handle and like the storage was nicer. Looks were not deceiving. The plastic box these come in is thin feeling, but durable enough for reasonable expectations. The inside organization foam with printed sizes is amazingly handy. Add in the anodized red and blue to differentiate SAE and Metric sizes and this kit is just so easy to use that it is incredible.

The threads in the gauges are smooth and high quality. The finish on the gauges are clean and nice looking.

I cannot recommend this kit enough for anyone who works with fasteners on a regular basis.

High quality timber screws - drive easily.

These are quality timber screws that have a finish that helps them glide into the wood easily. Great for landscape timbers and other construction tasks requiring strong, long fasteners. Very pleased with them.

What an Awesome Nut & Bolt Set - Best Nut & Bolts Ever!

I used these nuts & bolts on my beach cart. If you want the best nuts & bolts on the planet, you have just found them! Wow, what a difference they made on my application. I wish I had bought these nuts & bolts years ago.

Very sturdy material and great style!!

I bought this hooks for my front yard about a month ago. I love them!! They're strong and sturdy. I love the style and the material of the item. They're light weight but hold weight. Thy function just as expected. I would definitely purchase them again and do recommend them. Definitely great value for my money!

Work as expected, very reliable.

I use for drop mechanisms, very reliable, would I put them in a $600.00 plane, nope.
I have good luck with them, with rcskydiver, and drop box, highly recommend.
Out of 64 I had one act funny, Not bad.

no quality issues here, exactly what you'd expect, great deal

I've been using riv-nuts for a long time and they're a great solution when you need one. These are identical to the one's I've gotten from McMaster over the years. They crush evenly and the threads seem to be in spec. This is an extremely good value for the money! The case is nice, I love to see a label under the lid, and the included sizes range well for me. It's also very nice they come individually bagged so they don't end up disheveled from transit! I'm pleased to see so many of each size, even the big ones. This is a ridiculously good price for actual stainless steel!
