About This Product

Hey DIYers and mechanics - these Grade 8 hex flange bolts are the real deal! You get 50 pieces of seriously tough fasteners that can handle pretty much anything you throw at them. The 5/16-18 thread with 1 inch length under the head is perfect for all sorts of projects - automotive work, machinery, construction, you name it. The black phosphate and oil finish isn't just for looks - it provides solid corrosion resistance so these won't rust up on you. The flange design is brilliant because it acts like a built-in washer, distributing pressure evenly and saving you time. Full coarse threads mean they bite hard and hold tight.
