    • Awesome bolts!
Size: (10 Sets) 5/16x1-1/4"
I recently needed a robust fastening solution for a project that required strength and corrosion resistance, and this 5/16-18x1-1/4" Stainless Steel Hex Head Screw and Nut Kit with 5/16 Nuts and 5/16 Fender Flat Washers proved to be exactly what I needed. I'm extremely impressed with the quality and performance of these fasteners. Right out of the box, you can tell these are made to last. The stainless steel construction is top-notch, giving them excellent resistance to rust and corrosion, which is crucial for outdoor and other demanding applications. What really stood out to me was how incredibly strong these screws and nuts are. I put them to the test in a demanding application, and they held up flawlessly. There was no stripping, bending, or any signs of weakness, even under significant stress. The inclusion of the fender washers is a great bonus. They provide a wider bearing surface, distributing the load more evenly and preventing damage to the materials being fastened. This added stability and security is a big plus. The threads on the screws are clean and precisely cut, making for smooth and easy installation. The nuts fit perfectly, and the whole assembly feels incredibly solid and secure once tightened. If you're looking for a reliable and incredibly strong fastening solution, especially one that can withstand harsh conditions, I highly recommend this 5/16-18x1-1/4" Stainless Steel Hex Head Screw and Nut Kit. The quality and strength of these fasteners are exceptional, and they've exceeded my expectations in every way. Great set of bolts! ... show more

Size: (10 Sets) 5/16x2-1/2"
Got these to bolt down my miter saw to my workbench top. They are durable & a made of quality metal. They didn’t strip when bolting down and this set came with all the necessary items need to get the job done. Size were as advertised and fit the measurements to my miter saw bolt holes and long enough to go through my workbench. Would buy again if needed to bolt other tools down with similar bolt whole dimensions. ... show more
