Description

Hex Bolt Grade 8 Yellow Zinc 5/16″ – 18 NC

Hex Bolt Grade 8 Yellow Zinc 5/16-18 has a higher tensile strength then a grade 5 bolt

• Grade 8 bolts are made of medium carbon alloy steel that has first been quenched to harden them, then tempered to restore some ductility
• Grade 8 bolts are generally harder, but more brittle than grade 5 bolts
• Electro-plating gives grade 8 bolts their yellow sheen (yellow zinc) and provides some corrosion resistance; however, they will eventually rust if the coating is damaged or scratched off or if the bolts are exposed to high saline environments

Lengths available: 1/2″, 3/4″, 1″, 1-1/4″, 1-1/2″, 1-3/4″, 2″, 2-1/4″, 2-1/2″, 2-3/4″,  3″,  3-1/2″, 4″, 4-1/2″, 5″, 5-1/2″, 6″
