1/4" - 20 Grade 8 USS Coarse Thread Steel Alloy Hex Nuts
* Zinc Plated for corrosion resistance
Quantity: 100 Nuts (aprox 11 oz. net.)
Grade 8 nuts & bolts are considered some of the most durable and reliable available on the market. They are comprised of carbon alloy steel which gives them a high ksi rating.
Zinc or cadmium plated grade 8 nuts & bolts are able to resist corrosion.
The factor that makes grade 8 different from a lower grade is preload strength. Higher grade materials, such as carbon alloy steel, allow for greater torque strength. The preload, or thread tension in a fastener is higher when the type of steel being used is grade 8 in quality.
Grade 8 nuts & bolts are most useful for mechanical applications where high stress and strong load bearing pressures are a major factor.
One thing to consider is that it's usually a safe bet to go with the highest grade of nut & bolt you can. Manufacturers may recommend a lower grade, but it never hurts to go with higher quality materials. The worst thing that can happen is you paid a little more for the quality.
Therefore no refunds or replacements will be given unless clearly warranted. Each case will be judged fairly and the appropriate action taken.
I do appreciate your business.
