A beam type torque wrench is more accurate and stays in calibration while the click type don't - that's why many people prefer them. The beam type can be had with a lifetime warranty at Sears for around $25 for the 1/2".

A click type torque wrench should NEVER be set below the lowest setting - they will lose calibration. They should be stored set to the lowest setting, which is not 0. For the HF wrenches, it's around 20 ft-lbs. In addition, before use, they should be manually activated several times to lubricate the mechanism.
Point taken, I guess I should have said "lowest marked setting" instead of zero.

Quote from decolores9 :
I have both the 1/4" and the 1/2" from HF, and they are fine for "approximate" torque. The settings are not accurate though, especially for lighter wrenches like the 1/4". I tried several in-store with a calibrated standard before just accepting they were only about 20% accurate and read "high". They can be calibrated, but unless you have the tools to do this yourself it's not worth the cost.
My 1/4" HF torque wrench goes down to 35 inch lbs and 20% high would be about 42 inch lbs. If you're torquing on something soft and\or fragile like brass, plastic or aluminum... and if you're not careful there is definitely potential for an issue. And, if you place 100% faith in the tool and the fact that nothing can go wrong like maybe you set the wrench to the wrong setting (like you read ft lbs and the spec is actually either inch lbs or NM) you're asking for trouble. I guess for anything less than 42 inch lbs then I would just tighten without the torque wrench and hope for the best.

I know these are probably not considered the "approved standard" but for reference the Snap On brand click types in this torque range @ $250 plus are +- 4%. Isn't that an 8% accuracy range swing? At 20% high, and I don't know if that was confirmed on every torque wrench HF puts out or just a certain lot or even a particular wrench, I think $9.99 is worth taking a chance on as a DIY'er. If all else fails, subtract 20% on your torque setting.

Quote from decolores9 :
As a result, the 1/2" is OK for things like lug nuts where a wide range of torque settings is acceptable. The in-lb wrenches like the 1/4"and 3/8" are essentially useless and will cause damage if used out of the box without calibration.

My advice is that most people will get better results with a beam type torque wrench from Sears.
I'm not going to take every, or any for that matter, torque wrench I purchase, regardless what I paid for it and have it calibrated before use. The pro models, even the beams, are expected to be fairly accurate out of the box. Maybe one of the mechanics out here can chime in and tell what interval they have their wrenches cal'd at but I think you'll find a wide and varying opinion on that as well. Someone with a decent bench vise, a couple barbell weights and the ability to follow some basic math can roughly calculate the accuracy of a ft. lb torque wrench of either the click or beam type if desired.

Quote from decolores9 :
Torque wrenches were discussed in the mechanic's tools thread.
I have made a note of this for future reference. Thank you.

Quote from genec1 :
A beam is more accurate but more challenging to use, especially depending on placements. I'd recommend getting a good quality beam to match the click, especially if you're doing anything more than lug nuts on steel rims. Periodically use the beam to verify the click, preferably at 3 points and including the top torque you'll use the click for. Bear in mind how the wrenches move (especially the head of the click). 100lb-ft is a very common lug nut torque now-a-days. I bought 2 of the 1/2" clicks (#239) such that I strictly use the first and if I get uncomfortable with the first, I'll shelve it immediately and use the second.
That's a good idea and recommended if you have no faith at all in the accuracy of your torque wrench. I think rbreding's objective was to purchase the set of three torque wrenches from HF for about $30 and not have to buy a set of "standards" as well. Currently, the best price from Sears on a 3/8" beam 0 to 75 ft lb is $17.99 for (Craftsman), the 1/2" beam 0 to 150 ft lb is $22.49 (Craftsman), and the cheapest 1/4" drive beam is $76.09 (Armstrong) for a grand total of $116.07. Not a bad deal if you must have beam types but kind of defeats the purpose IMO. Again, my 2 cents and that from an unqualified DIY'er.

No disagreement that beam type torque wrenches can be more difficult to use in some situations, where you cannot easily see the scale while applying the torque. In those situations, a helper can usually read the scale, though.

Given the overlap in scales (12 in-lb=1 ft-lb), the HF 3/8" drive torque wrench is not really needed, since the HF 1/4" and 1/2" cover the range. As you note, there is no beam type Craftsman 1/4" drive wrench, and the resolution of the 3/8" drive beam wrench is 30 in-lbs.

However, there is a big accuracy issue with the HF 1/4" torque wrench. The first issue is that it operates differently than the other torque wrenches - there is only one "click" and it is very quiet and soft and easy to miss. They are hard to use, much harder than other click wrenches or a beam type.

Accuracy seems to be in the range of +/-50% out of the box, for the ones I tested. Unfortunately, I discovered this issue when I overtorqued valve cover bolts. I set the wrench to the correct 80 in-lb setting, but had oil leaks. Upon investigation, the 130 in-lb of torque the wrench applied at the 80 in-lb setting was enough to dimple the valve cover around the bolts. When I went back to the store and tested several, they were all over the place, but none within 20% of the set torque. In my experience and opinion, I can't trust the 1/4" HF and it is essentially useless.

To achieve accurate low in-lb torque settings, for bearing preloads, valve cover bolts, etc. a better choice is a screwdriver style beam wrench or a smaller beam wrench with a 0-50 in-lb range. It's a machinists tool and you can usually find them for $10 or so at flea markets, but they are getting harder to find.

I completely agree with the 3/8" being unnecessary. The only reason I have both 1/4" & 3/8" is because I bought the 3/8" first for a specific job. When another job came up and was below the range of my 3/8" I picked up the 1/4". Would not have bought them both if I had anticipated my needs correctly to begin with.

I have experienced the same with my 1/4" wrench. The lower the setting, the less defined the click. I usually use a single finger and move my whole arm to give myself the best chance of not missing that click or release.

If that is the case with the +/- 50% accuracy then I would definitely agree they are way out of tolerance. As I mentioned, and as you probably already know, this can be "rough checked" fairly easily with a decent sized bench vise and some weights to see the degree of accuracy on the ft. lb wrenches. This way you could check one before using it and if it wasn't any good return it for either a refund or give a replacement a shot but of course that's a hassle and not practical when you need to torque something now and have no back up. The inch lb ones will require a cal shop unless you have some smaller weight standards.

Agreed.

I've seen one recently on display. The website says in store only. I'd say call your local HFT.

You should be able to use a coupon on a sale item unless the sale is specifically mentioned in the exclusions. You cannot combine coupons on a single item, though they should allow the free item along with the discount coupon.

Remember, no running with a scissor lift.

Has anyone seen an item-specific coupon to get the 17' multi-position ladder for cheaper than $135 - 20% = $108?

There's also lubrication, contamination, etc that can change it over time. I trust it for now but I checked before first real use and I'll probably check within a year (already done several wheel swaps and such with #239). I just have no faith in it being accurate for my entire lifetime.

I agree, to an extent, G1. Another major factor would be the frequency of use. For instance, if you are only swapping wheels and tires seasonally for say 40 years that's 80 uses of normally 4 wheels times 4 to 6 lug nuts typically (equals 1920 cycles at 6 lugs over 40 years providing you're not using the same wrench to remove the lugs - not typically recommended). My understanding is that you should have your wrench recal'd after 5000 cycles or every 12 months and any time the wrench is 25% or more out of tolerance. For me, I'll be checking mine and if it goes beyond 25% then I'll make the determination as to whether or not I need to pay $30 or more to have it recal'd or if I can find a new one that's less than 20% out of tolerance for $9.99 at HF.

question, I'm trying to get the 68056 4 ton jack. I see coupons for this for $99 on ebay but can not find them on here. I did however find the coupons for 68048 and 68050 and I went through online and added these to the website shopping cart but when I put in the coupon codes it says they are not valid. The coupons state that they can be used online if the code is entered correctly, what am I doing wrong?

I snagged this from Avalon's post 3531 back on page 236. 4 Ton Heavy Duty Floor Jack with Rapid Pump and the Q is good until October 12.

If you are still having problems getting coupon codes to take in your cart I'd give them a call.

(No doubt someone will chime in and tell me that I'm breaking the cardinal rule of SD by suggesting someone make a call - let the barrage begin...)

Someone passed me this mag and I was pleasantly surprised to find this Q page inside. Nothing real special to see here but the air palm sander #98895 gets some pretty good reviews and it's less than half price with this Q. Oh and $9.99 torque wrenches, torque wrenches, torque wrenches... have we beat this one to death yet? Might be a good time for me to stock up though...

Posting both the .jpg and the .pdf since the .jpg isn't too clear and I wasn't sure how well it would print. The .pdf should print just fine.
