3/4-16X3" grade 8 bolts hex cap screws bolt steel zinc
Grade 8 bolts are considered some of the most durable and reliable. They are made of carbon alloy steel, that gives them a high psi rating. Zinc or yellow zinc grade 8 bolts help to resist corrosion.
Grade 8 Bolts: Strength and Durability
This makes a grade 8 bolt different from a lower grade bolt is its preload strength. Higher grade materials, such as carbon alloy steel, allow for greater torque strength in the threads of the bolt. The preload, or thread tension in a fastener is higher when the type of steel being used is grade 8 in quality.
The most useful areas for grade 8 bolts are for military, aerospace, or marine related mechanical applications where high stress and strong load bearing pressures are a major factor. The off road vehicle market also has a need for grade 8 bolts for the same reasons.
