Torque wrench questions

[Ripcode]

I currently do not have a torque wrench.

What would be the best range in ft/lbs to cover what needs to be torqued on an AR?

I have a Sear Craftsman that I use for my LMT and it has held up very well. It will do everything I need to work on an AR.

Paul, what is the range in ft/lbs of your torque wrench?

I cover the AR torque requirements under: FAQ's, BASIC INSPECTIONS AND PROCEDURES

ETA: Two torque wrenches might serve you better than one due to the range of torques:

a TW in ft/lbs


a TW in in/lbs.


Going from the lowest torque called out (Carrier Key Screws: 50-58 in/lbs) to the highest torque called out (Barrel Nut: 30-80 ft/lbs) you have a calculated total torque range of 50 to 960 in/lbs. A dedicated torque wrench covering each, in/lbs and ft/lbs, might serve you better.

Good info! Thanks!

And a thanks to Paul too! Looks like I have an excuse to go to Sears this weekend.

Alrighty... the Bobro mount nuts should be 14 to 20 in/lbs for torque.

I have been looking and the wrenches I can find so far are in in./lbs are 25 and higher.

Anyone know where to get one in smaller in./lbs increments or starting at 10??

For a torque that low, you might need to look at a torque screw driver rather than a torque wrench.

My personal 1/4" drive, in/lb torque wrench goes from 20-200 in/lbs which is a pretty normal torque range for that size drive.

ETA: Snap-On has a couple 10-50 in/lb torque wrenches in 1/4" drive, but you're looking at about $250.00+. A 5-40 in/lb torque screwdriver is about $210.00.....high prices to justify for some I would guess.

I know, I know.... And I like quality tools. The thing is I need this tool for one thing! LOL!

Brownell's has a pretty good selection of them that aren't nearly as expensive as what's been mentioned so far, but I don't have personal experience with any of them.

Put some blue loctite on the screws and hand tighten them until they are SNUG. I never used a torque wrnech on any of my optic mounts and they worked just fine.

I'll agree, I've gone without in the past, and the use of a torque wrench in this application is certainly questionable. Also, going without has not failed me either.

I opted to use a torque wrench with my ADM Aimpoint mount, after hearing about issues with optics working loose.I already own the torque wrench, the ADM mount recommended torque spec falls within the range of my torque wrench, so it only made sense to me to follow the Mfgr's install instructions.

Yes Sir, there are certainly more affordable options out there.

I've dealt mostly with Snap-On throughout my career, so from experience I always considered them top of the line when it comes to torque wrenches.

Thanks for all the helpful advice gentlemen!

I will forego the torque wrench for my Bobro mount, but I will still plan picking up a wrench or two for future tasks.
