White Oak inch/lb Torque Wrench Sale

White Oak Armament has their inch ounce scope installation tools on sale. Most damaged scopes that come into LGS were ruined during installation. Seems like very few people can twist up proper inch/pound or especially inch/ounce numbers with a standard driver and by feel. They have scope slipping so grab the wrench and twist up some more resulting in bent scope tube overtorquing their screws, often in misaligned rings. A scope lapping kit and inch/pound wrench almost guarantees a good job even using discount chinese scope rings off fleabay.

I found most DIY'ers don't know the difference between inch-pounds and foot-pounds. So when the manual says torque to 20 to 30 inch-pounds they go to 20-30 foot pounds. I have removed may scope base screws from receivers after they were wrung off from over torque.

I learned a hard lesson in torque a number of years ago ....

thought I could not damage a 12mm x 1.0 shaft bolt w/ a tiny little 3" long snap-on 3/8" drive stubby ratchet ..... damn, was I ever wrong !

Murphy kicked my ass across 2 counties and in circles for a week all while screwing my ass w/ a un-greased splintered broomstick

there is a damn good reason for the right torque wrench and that chart of recommended max torque values for a given size & grade bolt in a given material

yes, it cost me thousands of dollars and many hours of my time

I just saw it on sale and didn't check prices elsewhere. My inch/pound wrenches are Snap-On and Proto. Mine have to be capable of calibration and sent in for annual calibration. My smallest torque wrench is 0.1 to 3.0 inch/ounce adjustible and calibrated. Sit it next to my 2,200 ft/lb wrench with ten foot handle it's a funny picture but have wrenches in inch/ounce, inch/pound, foot/pound and Metric kg/cm plus N/M. Like my meters have clients that have to include serial number of wrench and date of last calibration on invoice if want to get paid. Have most in insulated as well so if see a price under a few hundred dollars don't pay attention as professional torque wrenches are not cheap.

I agree Huey but still have seen Snap-on, Proto, Williams, CDI and Armstrong torque wrenches fail. Much less than the Chinese wrenches though.

Not sure what is so great about them. They are torque limiting. I have used fasteners professionally and at home most of my life. The trick on small screws and such mounting scopes is to go back and forth in an x pattern until they snug down evenly and blue Loctite. Putting a scope on a rifle is somewhat tedious and some people don't have the mechanical wherewithal to be careful.

I picked up someone's rifle with a scope on it a couple of weeks ago and could automatically tell that the scope was not rotated to vertical in relation to the rifle.

I know what you mean Melt but Torque wrenches provide consistency at the least and are required in many applications.

Oh certainly. I have my 1/2" drive for stuff that needs it. Just never thought necessary for iddy biddy stuff.

Pretty much all you mentioned plus Craftsman and a few other "American Made" come from two factories with brand name placed for company who contracted a particular order. My calibration company has a very specific list of wrenches will calibrate as found themselves wasting a lot of time fooling with a wrench and having to return uncalibrated due to not staying in acceptable range at various settings to certify.

Right up till you wring off a screw in a $5,000 part owned by a client mounted in a cabinet on their site. Promise when specs are given in inch ounces better use a wrench as often putting fastener in brass grommet set in circuit board that will snap if over tighten and then your hosed. Just snug doesn't feed the bulldog if circuit board if in something subject to vibration.

Or crush/bend a scope tube over tightening even with proper pattern of moving wrench from fastener to fastener. I have seen a ton of crushed tubes and warped tubes though not gone that far myself but have broken a scope mount screw or two before purchased my first inch/pound wrench. Guy came in gun shop once had mounts for AR that thought were same height bought in zip lock bag at gun show. Turned out one mount was about 1/8" taller than the other and he didn't notice till "snugging" final turns on screws installing a $1,500 Leupold scope. Could not get it on paper at 100 yards, brought into shop and scope had two half moon crescent indentations. Torque wrench might not have kept this from happening but a torque wrench mentality might have measured used bargain mounts in unmarked bag with a caliper to verify same height.

If work on remote terminals, cell towers, in switching centers, etc for Ma Bell won't pay your invoice if model, serial number, calibration date and company of every wrench and meter used not listed on invoice. Even on items as mundane as a battery terminal where "snug" if fine till wring off stainless fastener attaching lug or break attachment to internal plate in a $3,000 battery. "Snug" is defined much differently by a 300 pound diesel mechanic than a person assembling smart phones on an assembly line.

An inch/pound wrench will serve any man that fools with guns and scopes much well over a lifetime. If saves one bo-bo or one scope slipping in rings on last shot before the trophy buck stepped out its worth the hundred bucks. Crap, time saved removing one shake off screw in something of just moderate value pays for a cheap one.

Huey I can understand a micro torque wrench; however, you drifted off into PC board stuff. Those little wrench sets for the rings make zero sense from your original point.

My point being I can use the supplied right arm do hickey and not slip nor mar said expensive scope. Sometimes I use a ball peen hammer to coax it into position albeit a smaller version

This ain't the HAL9000

Huey,
I'm pretty familiar with torque wrenches. I'm a calibration technician in a cal. lab. On occasion I get a Craftsman or Tekton in to calibrate but mostly the wrenches I mentioned.

I've seen many good (and a few excellent) wrenches in the list I referenced.
The surprising one was a Tekton that not only successfully calibrated but maintained repeatability in a very narrow range.

Admittedly, many labs probably see substantially more TW's than I as much of my time is spent on meters and testers.

Have a NorBar torque wrench made in England that my calibration service has borrowed it twice to do an off site quality control job. They usually calibrate whatever is in my pile at the time for free for letting them use it. Say it's most accurate wrench in its class and range have ever calibrated.

Meltdown,
When pay to have a scope built by U.S. Optics, Shepard, March or semi custom in Leupold custom shop or even nicer European custom built scopes on top of a blueprinted rifle proper torque on all fasteners is important to consistency and warranty. If wasn't top notch smith's would not bother with using them. Just randomly twist screws on scopes that cost $3,000 for an entry level and see how it works out. Some of my scopes had a licensed smith install so as to not risk warranty from doubts if I fared it by maker.

An old article on off shelf units in the $1,000 to $4,000 range. You can Google up customs and request a quote for scope and watch them climb towards five figures.

http://precisionrifleblog.com/2014/0...-rifle-scopes/

Saw a guy bring in a $5,000 ATN THOR had shanked the front screw off mounting to an AR 10 using a 3/8 drive ratchet and socket. Swore he had barely begun to snug it when popped. Between scopes walking and screws broken off in top of $129 PEPR mounts it's stunning to see what people do. Have my own calibrated Snap On inch/pound wrench at LGS so don't have to mule back and forth from work and bang around as have a couple there. Shop has one but not calibrated so won't use it when installing a Night Force for a client and risk an issue on my end. A $150 wrench when installing $1,500 scopes is a small investment in a job done right.
