"I repaired a floor using these and they are very easy to use. The old boards were in varying states and I was concerned at the size of the nails as smaller ones (round type)had clearly split the wood when used by the previous owners. These go in very well and without damage even very close to the ends of boards. They grip nice and tightly and I am well pleased with the results, just bought my second pack as another area of the house requires some repair. I found holding the nail straight until a good third was in the board helped keep the nail straight and true, also going in slowly to start with boards in very bad shape."
