HF Universal Impact Joint Sets, any experience?
Harbor Freight offers two versions of Universal Impact Joint Sets. The
first style, Item 67986 I am familiar with. Been using that style for years in my hand sets. The second one, Item 67920 I am not. Any advantages to the second version. Stronger, work better, horror stories... http://www.harborfreight.com/3-piece...set-67986.html http://www.harborfreight.com/2-piece...set-67920.html I'm not particularly fond of Universals, but sometimes they save the day. I see they have a set of Impact Wobble Socket Extensions too, that might be a better way to go. I really like my 3/8 standard drive wobble extensions. Would like something beefier though for use with my 1/2 inch impact wrench. http://www.harborfreight.com/3-piece...set-67066.html -- Leon Fisk Grand Rapids MI/Zone 5b Remove no.spam for email |

The 2 piece set contains just 3/8 and 1/2 inch but they use a different design to achieve the "universal" action. Not sure if you understood that or not...

Good quality ones will have a spring inside to hold the socket at an angle to make it easier to place on a bolt in a tight location. Andy |

Ditto. I have seen more sockets fly off at high speed with the 67986 style than the 67920 style, which is why I prefer the latter.

I've seen wobble extensions break at the thin portion, too. All are Pittsburgh, so if you have an HF store local to you, go for it. They're lifetime guaranteed and likely to last at least as long as the Crapsman crap Searz sells. -- Learning to ignore things is one of the great paths to inner peace. -- Robert J. Sawyer |

Would like something beefier though for use with my 1/2 inch impact wrench. http://www.harborfreight.com/3-piece...wobble-socket- extension-set-67066.html First, very little of what I do involves impacts, and like you, I'm not crazy about universals in general. However, even for hand use, I very much prefer the second (ball) type. I have three; 1) A maybe 15 year old 1/2" drive Snap-On with almost zero use. 2) A 40+ year old 3/8" Craftsman[1] thats had tons of hard (hand only) use/abuse... at least several times a month since new. 3) Last but not least, a 5 or 7 year old 1/4" Snap-On thats also seeing moderate to heavy service. They're great, wouldn't be without them! They don't have nearly as much propensity to 'wind up' and walk sockets off bolt heads and nuts, and in my experience don't become nearly as floppy, even after much use. Like all universals, the straighter you can keep them in use, the better. Remember, I've been talking hand use here. If your going to do a lot of impact work, you'll probably be much happier with a set/s of universal sockets. Yes, I know they cost mega bucks. Erik [1] Way back when (and maybe even today for some mfg's) they used to tack weld the cross pin's of these type universals. I suspect that cracking at the weld/s was an issue, as most now have swaged collars retaining the pin. My 3/8" joint is the older/cheaper welded type, and is much smaller in diameter than all the collar types I've seen lately. The smaller diameter has been just the ticket on more than a few occasions through the years. So far, it's hasn't cracked... don't know to attribute this to exclusive hand use, luck of the draw, or both. |

It looks to me as though the first style can drive at more extreme angles, while the second style is shorter, so if elbow room is at a premium, they would be preferred. Also -- the first style goes on down to 1/4" drive, while the second only handles 3/8" and 1/2" drive. I see they have a set of Impact Wobble Socket Extensions too, that might be a better way to go. I really like my 3/8 standard drive wobble extensions. Would like something beefier though for use with my 1/2 inch impact wrench. http://www.harborfreight.com/3-piece...set-67066.html Perhaps as restricted in angle capability as the second set -- or perhaps even more restricted. So -- the question is -- how often do you need the greater angle of operation? They are a lot less efficient at such angles anyway.

HF Universal Impact Joint Sets, any experience?
I was never a fan of the 3-piece universal joints, even for hand tool use..
and yes, I worked with tools for income for many years. A powerful impact wrench, which generally always speeds up immediately when the load is suddenly removed, is entering a potentially hazardous area.. hazardous to the user and anyone nearby, but also risking damage to someone else's property. The 2-pc sockets have less joints, meaning less loss of power, and they don't have a position where they can lock. The 3-pc universals or sockets are generally weaker and will throw parts or sockets when they lock, or break, and/or cause the user to figure out a better solution. Using a universal joint also intrduces another sloppy joint in the power chain when a socket follows. All accessories used on air or electric impact tools need to have locking pins to engage the next part (not ball and detent attachment), IMO, not just because OSHA or other agency states it. I have the ball-joint 2-pc sockets and also the 2-pc separate universal joints which incorporate the locking pins, and no related injuries, so there's that part of a debate. Much of the experience with my ball-joint type drive accessories was in a lower power range of a 3/8" drive impact, for rapid removal of auto body sheetmetal or used without universals for various trim panel fasteners. Utilizing a control valve at the air inlet of an impact driver will allow the user to limit the maximum speed of the air motor if the fastener or drive accy suddenly disengages. This feature is also helpful for detecting a fastener that is frozen, which may just snap unexpectedly with full power applied. When using 1/2" drive accessories in general, and with a ball-joint universal, I always wear leather gloves and pay strict attention to what's taking place at the fastener. YMMV.. as well as the perceived usefulness of your eyes and fingers. -- WB .......... "Leon Fisk" wrote in message ... Harbor Freight offers two versions of Universal Impact Joint Sets.
