100 Pcs 5/16-18x1" Grade 5 Hex Flange Bolts - Serrated Zinc Coated Full Thread

About This Product

Hey DIYers and mechanics, this 100-piece set of 5/16-18x1 inch Grade 5 hex flange bolts is seriously handy to have around the workshop! These aren't your ordinary bolts - the serrated flange design means you often don't even need separate washers since the built-in flange acts like one and bites into the surface to prevent loosening. The Grade 5 rating means they're strong enough for most automotive and construction applications without being overkill. With coarse full threads (that's UNC threading for the pros), they're easy to start and provide good holding power. The zinc clear coating gives them decent corrosion resistance for both indoor and outdoor projects. The 1/2 inch wrench size makes them easy to tighten with standard tools, and at 1 inch long under the head, they're versatile for various thicknesses of materials. Having 100 pieces means you'll have plenty for current projects and leftovers for future repairs. Perfect for automotive work, furniture building, machinery repairs, or any project where you need reliable, medium-strength fasteners. Much better than running to the hardware store every time you need a specific bolt!
