Hex Bolt Grade 8 Yellow Zinc 5/8 – 18 NF

Description

Hex Bolt Grade 8 Yellow Zinc 5/8 – 18 NF

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

• 5/8″ – 18 TPI (Threads Per Inch) Fine thread bolts
• 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″, 1-1/4″, 1-1/2″, 1-3/4″, 2″, 2-1/4″, 2-1/2″, 2-3/4″, 3″, 3-1/4″, 3-1/2″, 3-3/4″, 4″, 4-1/2″, 5″, 5-1/2″, 6″, 6-1/2″, 7″, 7-1/2″, 8″
