Get a set of 3/8" drive allen socket adaptors. They are a lot stronger and can be spun just as fast when the allen screw is loosened.
Avoid Asia made models and their US suppliers like Harbor Freight. US made tools such as Snap-On and Craftsman are good. Here are some sites:

- handles are good for benchwork and esp. on MC's. I used the socket driven, hex bit holders (Hansen?) when a pro wrench. Those bits are far beyond the normal high quality "black" hex allen wrench but somewhat clutzy for small entry areas.I don't use T handles. I use the L shaped ones and have have made a bunch of handles. I use different sizes of aluminum rod with a hole drilled through it and a groove milled in the length. Slide the wrench you need through the hole and the L piece goes into the slot. I have thought about adding a retainer but you only need the handle to break loose or tighten. Anything of any size I go to the type that have use sockets.
Most of Craftsman tools are now sourced from China.
You might find this article interesting; it discusses galling with stainless steel bicycle couplings. It's amusing that while we all argue over the "best" gun lube, they're all pretty much the same with only two exceptions, and some are even worse than no lube at all. It makes me want to switch to Krytox, but it ain't cheap.Or stainless steel galling. We're encouraged to use stainless fasteners in our panel builds, but I've cursed and screamed at more than my fair share of 1/4-20 nylocks. They seem to seize up on me every. Single. Time.I don't know if we got a bad lot of them or what, but since these enclosures aren't being placed in especially corrosive enviornments, I "cheat" and use plated nylocks instead to save myself wasted time and frustration. Haven't had one seize yet since I started doing that.
