5/8″-11 x 3″ Yellow Zinc Hex Head Cap Screw Grade 8
Grade 8 Hex Head Cap Screws are manufactured from medium carbon alloy steel that has been quenched and tempered for strength. Grade 8 is the highest grade offering of the SAE J429 classification with a minimum tensile strength exceeding that of Gr.5 by 25% to over 40%, depending on the diameter. Grade 8 HHCS are commonly used in heavy construction equipment, commercial vehicles and applications that demand a high strength fastener. Hex Head Cap screws feature an integral washer face under the head for a smooth bearing surface and a chamfered thread at the tip to allow for ease of assembly. They can be used in a threaded hole or mated with a nut in a through bolting application. Grade 8 bolts are identified by a head marking with 6 radial lines evenly spaced 60 degrees apart. They meet the material specification SAE J429 Grade 8 and can be supplied either in a plain finish or with a Zinc Yellow (Dichromate) plating with a chromate secondary layer that offers additional protection from corrosion and has an attractive yellow/gold appearance.
