Grade 8 Bolts
Grade 8 bolts are considered some of the most durable and reliable one can find. They are comprised of carbon alloy steel, thus giving them a high psi rating. Zinc or yellow zinc grade 8 bolts are available to resist corrosion. We have these, and any other types of bolts you need here at NutsandBolts.com. Our easy to navigate website makes shopping for the right fasteners simple.

Grade 8 Bolts: Strength and Durability
The factor that 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. One thing to keep in mind is that it's almost always a safe bet to go with the highest grade of bolt you can when in doubt. Manufacturers may recommend a grade 5 or grade 6, but it never hurts to go with higher quality materials. The worst that can happen is that you paid a little more for the peace of mind.
