Tools with tighter tolerances?
Are there any brands of tools, especially Allen wrenches, that aren't sand blasted or whatever to round all the edges? Seems that even my brand n ew Bondhus allen wrenches are rounded and sloppy. That's not great when torquing stainless bolts.

Honest question: how do you know it is not the bolts? That said, I have Wihas and Pedro’s that have well defined hexes.

Wera offer a hex plus design that supposedly puts more contact with the screw.
https://www-de.wera.de/en/great-tools/hex-plus/ But I agree with the above poster that precision require both the tool and the screws to be manufactured at tighter tolerances. |

Both the bolts and the hex wrenches are manufactured to certain tolerance windows, and to make sure tools and bolts fit together, the tolerance windows can't overlap. But that doesn't mean precision hex wrenches can't be manufactured closer to their maximum allowed tolerances to ensure a closer fit.

Silca plating method used on their hex tools to tighten the tolerance range. Explained nicely here: https://youtu.be/7dDVVAcGoZU?si=nIMp5YPLum6PedKW

Really liking my wera hex plus. Definite improvement over Bondus an Ekland for stubborn hex bolts

Which Bondhus version are they? They make a variety of quality levels and their higher end ones are of better quality.

As mentioned Wera Hex Plus is what you need.

All the good ones have already been mentioned, but I'll toss in Stanley Proto and Eklind as well.

I have a set of the Silca wrenches. I wouldn't pay full price because I'm cheap but at the sale price I got them at they are fantastic. Very high quality. However I never had a problem with any of the mid-grade wrenches I owned over the years either. I think my main set for the last few decades was a mid-level Bondhus.

Ive used a variety of bondhus, wera, eklind, and even Pittsburgh icon allens for my career over the last 10 years. All were the cheapest variety I could find, so I imagine lowest level. I've put them all through thorough abuse, especially throughout my apprenticeship, and they all perform the same. I always get a good laugh when I see the Silca $200 set
If the wrench fits loose, either the tip of the wrench is being rounded off from so much use, or improper engagement in the screw head... or the screw head isn't right. If the portion that engages with the screw is worn and slipping in the screw, cut the worn out part off and continue on. If it's the screw, chuck it when you are able to remove it and replace to save yourself a headache later on. Once the screw is buggered up just a little bit, it doesn't take long for it to get entirely ****ed. |
