Need some serious heavy-duty bolts? These Grade 8 hex cap screws are built tough. Made from hardened steel and finished with a yellow zinc coating, they resist rust and corrosion better than your average fastener. Each bolt is 5/8 inches in diameter and 6 inches long, with a coarse thread (5/8-11) that bites into materials securely. The hex head requires a 15/16-inch wrench for tightening. They come in a set of 9, so you’ve got plenty for your project. Use them for structural applications, machinery, trailers, automotive work, or anywhere you need high tensile strength. Just remember: Grade 8 means they’re heat-treated and strong, but always consult a professional if you’re using them in critical load-bearing situations. The yellow coating isn’t just for looks – it adds an extra layer of protection against the elements. Whether you’re fixing a farm implement, building a rack, or securing heavy equipment, these bolts offer reliable holding power. Keep a set in your workshop for when you need something sturdy and dependable.
