ABSTRACT:
A nail includes a shank with a head and a tip portion on two ends of the shank. Two guide flanges extend radially outward from the shank and a flexible and deformable sleeve is mounted to the shank and located between the two guide flanges. The nail penetrates an object and defines a hole which is defined by a periphery which cuts into the sleeve so that the nail is cannot be pulled out from the object.
