I had a seized bolt with a torque spec of only 20 foot lbs - I was totally befuddled! Turns out it's from Loctite!!
Loctite 262 red threadlocker is compatible with metal materials with a 24 hr cure time. Delivers great performance with a shear strength of 1450 psi
It’s still nowhere near a pneumatic 2-1/2″ drive with 10,000 ft-lbs of forward torque and 20,000 ft-lbs of nut-busting.
So the Auto Shop doesn't have to worry about Loctite and thus uses loctite even though the torque rating is low....
Presto!!
The DIYer can't get it off!!
For instance, Ingersoll Rand’s newest high-torque cordless impact wrench can generate 1500 ft-lbs of nut busting torque

Well unless you get a very expensive Cordless!!
That's a $350 dollar Cordless Drill!!
Luckily the job I was trying to do was from an error by the Auto shop - so I'll just bring it back to the auto shop for them to fix the error they made. hahaha.

For example, 2,160 pounds per square foot converts to 15 pounds per square inch (2160 psf ÷ 144 = 15 psi).
The notations of lb-ft and lb/ft are NOT equal. The / is very often used to denote the word “per” as in pressure lb/in^2 = pounds per square inch (pressure) which is represented by formula F (force) = A (area) x P (pressure).
To calculate PSI from newtons, divide the force by 4.448, then divide again by the area in square inches.
