I bet someone with a mig welder could sneak in a tack weld to a bolt and let you run the whole screw out...

I hear ya on HF being junk. 2.5 mm is a tiny hex/allen . I dont care who makes it , its a crap shoot to turn one that small and not break it off. I needed a set of ball-end allens and my 3 mm broke first use too. Im a Millwright and I do buy tools from HF because most of the time , their tools are fine for what I need to do. I just buy their impact grade allens and sockets and so far ,so good. Their issue is their return policy, if it came in a set , the entire set it came with has to be returned . They wont just exchange the broken one for another. A couple ideas on how to extract the broken piece....possibly, find a rare earth magnet and put it up close to it and then take a small hammer and tap the sides , maybe the vibration and jiggling will coax it out.The following is not strictly brewing equipment, but equipment related to and used with brewing. If I've posted to the wrong forum, please move this post to the correct forum.
I have separate tools used on brewing equipment than for general household work. These include screw drivers, wrenches, etc. Maybe an "overkill", but I've used all my regular household tools for many things over the years including working on cars, fixing lawn mowers, working on bicycles, household repair, garage repair, etc... etc... etc... Just doesn't feel right to me using these tools anywhere near by brewing equipment.
Recently I needed a 2.5 mm hex wrench to tighten the coupler between the mill moter and the mill. Used a Kobalt household hex key set I purchased from Lowes a few years ago. Yes, I've used the Kobalt set for bike repairs/tweaks, but I didn't have the metric size needed for the coupler so I used the Kobalt hex key. Never had an issue. Also, never had an issue using the Kobalt hex keys to tighten the crap out of things.
Was recently near a Harbor Freight and, against my better judgement, purchased a set of standard and hex keys.
Used the Harbor Freight 2.5mm hex key for the first time today. Barely turned it in the coupler screw and it snaps off. A piece of the 2.5mm hex key is stuck in the coupler screw. Luckily, the coupler screw is tight and I was able to mill as planned. Nothing similar ever happened with the Kobalt set.
Now, of course, I can't remove the coupler from the shaft as part of the 2.5mm hex key shaft is in the top of the coupler screw.
Harbor Freight, IMO, equals junk, junk, junk. Doesn't matter if there is a 20% off coupon, a 40% off coupon or even a 100% off coupon, Harbor Freight is junk. Harbor Freight items are just inferior quality. Probably Chinese junk.
Now, my second problem. How to remove the bit of 2.5mm hex shaft in the screw of the coupler? I tried to reverse drill the 2.5mm kex key shaft stuck in the coupler screw using the smallest drill bit available. No luck.
I was hoping to be able to turn the 2.5mm hex shaft with needle nose pliers, but the break is flush with the top of the coupler screw.
Any suggestions?
Thanks.
Yup, that's probably too small for the job. But there's not much choice in flush/snagless bolt heads that size either. Although should one expect the allen wrench to snap off a tad higher up?2.5 mm is a tiny hex/allen
The HF hex key material should be soft enough to drill seeing as how it snapped off in the first place. I'd just drill a hole down the center large enough to remove most of the material. Then slip the other end of the drill bit into the hole and wiggle it, just a little bit. Hit it with a few drops of WD-40, PB Blaster, or Kroil before you drill; the heat generated by drilling will draw the oil in and help free it.
Thou shalt not buy tools less than Dewalt lest thee shall regret.
I understand your frustration when your tool broke, but it was a 2.5mm hex. It flexes with finger pressure. You can't get too surprised with shearing when you overnighted. Furthermore, given this site and what we do here and what you were doing... was beer involved? I've used beer-superpowers to break things more than once.Returned the broken hex set to HF over the weekend for a refund. Person asks, "Why returning?". I reply, "These are sh*t". Surprised look and "Oh". Refund received.
It is something of a crap shoot.
I am still looking for a tarp that can last more than 10 months in the California sun though.
