What are torque specs for socket head screws?
The below chart refers to usage in steel. Proper torque spec varies depending on the material, bolt grade or wether lubrication is used such as oil, wax, or anti-seize Always go to the manufacturer for proper torque specs if needed. Lubrication added to a dry bolt will typically reduce the torque value 15-25%.

What’s the proper way to torque a head bolt?
DO IT RIGHT OR DON’T DO IT. It is very important to torque your head bolts correctly. The actual preferred method for attaining the proper torque is by figuring out the fastener stretch, not by using a torque wrench. When torquing, you are applying a clamping load on the object you are torquing.

What does torque mean on a head bolt?
A crucial component of engine building is setting the torque on head bolts. Torque refers to how tight a bolt should be. When setting the torque, reliance on the specifications set by design engineers is vital. One essential tool you must have is a good quality torque wrench. Without one, you are like a ship without a compass at sea.
How much torque do you need for a cylinder head?
Usually, you start at one bolt, and you work your way around in a circular pattern. Doing so ensures that your head won’t be warped during the tightening sequence. The manufacturer usually stipulates that you must tighten the bolts in incremental steps. For example, suppose the final torque on a bolt is 40 foot-lbs.
What does the torque sequence mean on a cylinder head?
Torque sequence refers ro the pattern in which you tighten the bolts. The overall goal is to spread the torque evenly as you are tightening the bolts. Usually, you start at one bolt, and you work your way around in a circular pattern. Doing so ensures that your head won’t be warped during the tightening sequence.
What are the torque settings for head bolts?
SOURCE: head bolts torque settings According to my haynes manual for G-S reg, 1989-1998 it goes as follows, Stage 1:- Tighten all bolts by hand until bolt heads just contact cyl. head. Stage 2:-Tighten all bolts to 40Nm or 30lb ft. Stage 3:-Angle tighten all bolts a further 60 degrees. Stage 4:-Angle tighten all bolts again a further 60 degrees.
What are the torque requirements for bolts?
The required bolt clamping force for a joint is 20000 lbs. The torque required for a 3/4″ dry steel bolt to achieve this tension can be calculated as. T dry = (0.2) (20000 lb) (0.75 in) = 3000 (in lb)
What are the torque specs for the intake manifold bolts?
To ensure engine stability, engine bolts must be torqued or bolted down to a certain weight specification under manufacturer guidelines. The fuel rail bolts to the intake manifold at 7.42 foot-pounds of torque. The nuts and bolts of the intake manifold connect to the cylinder head at 30 foot-pounds of torque.
What does torque mean when tightening bolts?
When you tighten a bolt in a bolted joint, you use a twisting force, called torque. Torque is related to bolt tightness , but many additional factors – such as friction – combined into a single “nut factor” can have a significant impact on the relationship of torque to the tightness of the bolted joint.
