You have to wonder if a shorter length adapter is better or does really make no difference? The Bosch and the Milwaukee Shockwave 1/2 drive adapters are only 2 inches in overall length and the Milwaukee 3/8 shockwave is just 1.85. And both the Milwaukee 1/4" and 3/8" adapters leave just 3/4" of shank between the collet and the bottom of the socket. I don't have the 1/2 inch Shockwave to measure
The Titan and TSC ones are longer so both those have 1-1/4" of shank exposed.
Not many seem to advertise a specific torque value but I see the Dewalt 1/4 inch drive adapter list a 2000 in/lb (166 ftlbs) rating on both the 3/8 and 1/2 size. Doesn't give an overall length though that I can see
So is there a specific spot adapters usually break or is it just a random thing.
I'm guessing for the price of most 1/4 hex socket adapters you have to pretty much consider them as a disposable wear item if they do break. :confused3:
I have a 6 inch long Milwaukee
quick load extension not exactly designed for square drive sockets but can always jury rig something up in a pinch with an adapter. But I don't care to break it either its easy to wreck a spring loaded quick release holder using an impact driver. And at $10.00 each they are not all that cheap.

That one came as part of Shockwave bit kit. There are also a 3inch and a 12 inch available.
So while working on my riding mower recently using a socket with short adapter on my impact driver (seems that I never grab a ratchet anymore :laughing: ) I began to realize I just couldn't easily reach what I needed to. Got me started thinking maybe having something x-tra long like these
6 inch socket extension just to have around or put in my work tool bag if needed. No clue how they might hold up. I also looked at some wobble extensions but reviews were pretty mixed on those. :confused2:
I read some where that using long extensions and drive adapters actually reduce the power load to the fastener.
