Ball-End Hex Keys

I purchased both metric and AS of truss rod hex keys (Allen wrenches), with difficult access to the relevant internal adjusting bolt making it hard to determine exact size to use. The round - or ball - end on these wrenches allows one to approach the bolt from the slight angle (which is necessary unless you have the specific size in a specially designed/angled tool) required because of an interfering cross brace. Short story is that the ball end enabled me to determine best fit and make required (albeit small) adjustment. If you know what size you need, get the specific and best tool. If you don't, these did their job for me, were reasonably priced and quickly shipped. Recommend.

I got both sets , and have used a few already , the quality of these is absolutely top notch , they are strong and sturdy . Why get cheap substandard stuff when for a very reasonable price you can get something that's gonna last and that you have total confidence in !!!

My allen wrenches were all messy in a box. Now I have these two cool organized ones. It's great quality too!

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!
