Hex Head Cap Screws-Bolts Grade 8 Fine

Grade 8 Hex Bolts (Hex Head Cap Screws) - Fine Thread

Grade 8 / Fine Thread / Hex Head / Yellow Zinc Plated

A grade 8 bolt is stronger than the more commonly used grade 5. It is made of alloy steel and has six radial lines on the top of the bolt head. Grade 8 bolts have a tensile strength of 150,000 pounds per square inch. We recommend using grade 8 nuts, flat washers and high alloy lock washers with any grade 8 bolts / hex cap screws.

Bolt pictures are a general representation and not an actual picture of the product you will receive. Threads will vary according to the individual bolt sizes and dimensions. ISO standards for threads are: length is twice the diameter of the bolt plus ½ inch. If you are looking for fully threaded bolts please call direct at 800-872-5557.
