AN BOLT GAUGE

Thank you for getting it to me so fast! I will be ordering some A/C bolts soon!

A real must for anyone doing any aircraft repair. Easy to read.

Handy quick reference tool that removes the guess work.

Great! Made it easy for me to figure out what size bolts I had and needed. Not knowing anything about AN bolt sizes and types, it can get confusing but this helped with that!

Excellent! First of all I would like to say how helpful aircraft Spruce was on the telephone. I am a new aircraft builder and the AN bolt regiment is a bit confusing. This device takes the mystery out of it. I was able to go through my hardware and organize and label. Basically it’s a lifesaver. I highly recommend getting this device as one of the first tools you buy. Oh, as in an ending note, I received my order the very next day even during the Covid crisis.

Cool little gauge, especially if you do some of your own work

excellent

Excellent tool

Just what I needed and very fast thank you very much.

Product was right on time.

A durable all-metal gauge that makes aircraft hardware identification easy.

Its exactly what I wanted, and expected.

A simple gadget that does just what I need it to do . . .

Excellent product to keep organized. I was extremely happy how seamless the transaction, shipping and time frame was!

Get one!

If you are building or maintaining an airplane, you need this! I dont know how I got along without out it before. So much easier than measuring.

The order process was straightforward. Delivery was timely. This product now uses lighter gauge steel than the one it replaces. (But isnt that the case pretty much everywhere?) Rather than lines painted directly on the steel they are now applied using a thin plastic film overlay.

Great time saver. No more guessing what size or length a bolt is. Perfect for keeping your hardware assortment in order.

Now if only they would come up with a tool to identify nuts and washers by type and size AN

I bought one of these a few years ago. Had to calibrate it with a hammer because the decal wasnt on it straight. Very useful gage, but check it against another one, or known bolt sizes to make sure the length is correct.

Highly disappointed in this purchase. I bought the bolt gauge to assist in the education of A&P students at our local college. The metal has a sticker affixed to the front of it that has all of the bolt length info. The sticker was put on slightly crooked and also applied at the wrong height. As a result, the bolt gauge doesn’t read correctly. Poor QA job on this one. Will look to return this item in hopes this was a one-off. I expected better.
