Our OEM style bolts are exact factory sizes with the same head style and strength ratings (10.9 grade) and meet or exceed the factory specs. 10.9 grade bolts are very strong, heat treated fasteners and wont strip out or round off like cheaper 8.8 grade bolts offered by other companies. These are all heat treated and zinc plated to look great, resist corrosion, and last the life of your motorcycle. They are stronger and lighter than the stainless steel bolts being offered by other companies as well. -Can I find these at a local hardware store?- As most of us know from experience, OEM style fasteners are not available at our local hardware stores. The metric hex bolts found at Ace or Lowes are not the same. These fasteners are only found at the cycle dealerships and expensive to purchase on an individual basis. It's nice to have them on hand, right when you need them. -Will I get every nut and bolt found on my bike? What isn't included?- This kit is designed as a maintenance only kit and is a great assortment of the most commonly used fasteners found all over your bike. It is not a full on restoration kit. It doesn't include shock or suspension/linkage bolts, axles/axle nuts, swing-arm bolt, and no case bolts longer than 45mm.
