I've both imperial and metric kits and they serve me well almost daily. These are literally the most used tools in the shop!

Allen wrenches that work very well for adjusting truss rods. The ball ends help for acoustics with the adjustment end in the sound hole so you can turn at an angle.

An absolute must for any guitarist's toolkit. Get the Metric and the SAE and you are set.

I can't live without them. Buy both inches and mm
sets.

I have sets of Craftsman Hex Keys that I don't reach for when I need to adjust something on a guitar. These are far better and they were less expensive.

Bought both sets, use them all the time.

These allen wrenches are superb. Their sizes are accurate. Durable. The long handle construction give you the leverage to adjust hex shape truss rods with ease and accuracy!

A good quality product with a reasonable price. You must have it!

I needed a 2mm for the knobs on my Schecter. Figured I'd just get the whole set, given the low price. Works perfectly, I like the ball end for angles. I'll probably get the SAE set, too.

it's a must have set buy cause you'll need it for
