Description
Hex Bolt Grade 8 Yellow Zinc 7/16″ – 14 NC
Hex Bolt Grade 8 Yellow Zinc 7/16-14 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: 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″

Charles –
The bolts are excellent grade and appearance but I was disappointed that they were advertized as having patial thread but they are not. Had to use them anyway but the application would be better suited to shouldered bolts. Don’t go by the picture.
