How much torque does a barrel nut need?
Torque past 35 foot-pounds, until the next hole in the nut aligns with the gas-tube hole in the receiver, but do not exceed 80 foot-pounds. After aligning the barrel with the receiver and installing the barrel nut, use a torque wrench in conjunction with a barrel wrench to properly tighten the nut.
What is the proper torque for a Picatinny rail?
The recommended torque values for tightening screws of individual assemblies for mounting optics given in in/lbs and Nm are: when mounting a Weaver/Picatinny rail on the action, 15-55 in/lbs or 1.69-6.21 Nm (Badger 15 in/lbs or 1.69 Nm), Warne and Nightforce 25 in/lbs or 2.82 Nm, Vortex 55 in/lbs or 6.21 Nm);
Does Leupold recommend Loctite?
For example, we do not recommend the use of Loctite or other similar products in mounting our optics. These products can act as a lubricant, creating additional torque on the screws, which can exceed the recommend specs and actually damage your riflescope, limiting your ability to dial shots.
Can you over torque lug nuts?
Excessively tightened lug nuts can strip the threads, distort brake rotors, damage the wheel, and possibly shear off the lug stud.

How do you calculate nut torque?
DETERMINING TORQUE
The general equation for bolt load based on applied torque is T = KFiDb where K = torque coefficient. K is a function of the coefficients of friction and collar friction in the joint, and these are based on variables such as surface finish, coatings, and so on.

When should you not use Loctite?
Avoid using threadlock on frequently removed small nuts and bolts, especially on light-duty bolts, such as those used to hold on side panels. Loctite should never be used on radiator shroud bolts. Why not? The radiator shroud bolts thread into nuts that are embedded into the plastic gas tank.
Should Loctite be used on scope mounts?
Is it better to over torque or under torque?
They’re all tools designed to both fasten properly and to prevent over-tightening or under-tightening a bolt. Over-tightening can cause damage to the fastener, and under-tightening can result in making the item you are attaching or assembling structurally weak and potentially unsafe for use.

What if I over torque my lug nuts?
When you over-torque the lug nut you could cause stress fractures and this makes it no longer certified for the load rating, there is a risk of the lugs breaking under normal conditions and your wheels will pass you in traffic, rare, but it does create a safety concern.
What is the tightening torque?
Torque tightening is the accurate application of torque to a nut so that a bolt can hold its load securely without breaking. Too little and our materials aren’t properly tightened – making it structurally unsafe.
