a grade 8 bolt is stronger, about twice as strong.
The torque needed to loosen a bolt or joint is often much higher than the torque needed to put the bolt in in the first place. There is no set value difference between the two, unfortunately.
grade refers to composition and strength. Generally a higher Grade ( number or alphabet) is a stronger material. For example Grade C is stronger than Grade A Grade 8 bolt is stronger than grade 5 bolt.
A grade 5 hardness bolt is a bolt made of medium carbon steel and depending on the manufacturer can either be or not heat treated.

They are grade eight, and a special length. Do not use a normal bolt.
A type of indicator of the temper (grade) of the bolt. I think 3 lines = grade 8. other bolts use different indicators, too. on japenese bolts, sometimes a dot is used so they can count revolutions to reach desired torque of bolt without using torque wrench. hope that helps ya.
The first thing we have to know is--what torque? Is it Head bolt torque, rod bolt torque, main cap torque, water bolt torque, or something else? Please specify.
The bolt holding the blades on a John Deere L108 mower is typically a 5/8-inch diameter bolt. It's important to use the correct grade of bolt, usually a Grade 5 or Grade 8, to ensure durability and safety. Always refer to the owner's manual for specific maintenance guidelines and torque specifications.
Consult a generic torque specification chart based on the size and grade of the of the bolts (top of bolt will have that info on it).
To arrive at the proper bolt torque, you start by determining the specifications required for the joint, which includes factors like bolt size, material, and the type of joint. Next, you refer to torque tables or guidelines that provide recommended torque values for the specific bolt grade and size. It's essential to consider the lubrication condition of the threads, as lubricated bolts require different torque settings than dry ones. Finally, using a torque wrench, you apply the specified torque in a controlled manner, often following a specific sequence to ensure even distribution of load.
The torque specification for a 3/4 inch supertitanium bolt can vary based on the bolt's grade, thread pitch, and application. Generally, a common torque range for a 3/4 inch bolt is approximately 150 to 300 foot-pounds. It's essential to consult the manufacturer's specifications or relevant engineering tables for precise torque values tailored to specific uses and conditions. Always consider factors like lubrication and joint conditions, as they can affect the required torque.

The bolt could have been faulty, or the torque wrench may not be calibrated.
The torque of a water pump bolt can be requested from the manufacturer. The Chevy Trailblazer has a high torque for the water pump bolt.
