THE BACKGROUND OF THE INVENTION
It is troublesome to repair a flat tire especially in highway where no auto-body shop near. The flat tire repair kit at present on the market which contains an inserter, band rubber and super glue is not easy to use because the tire has to be removed from wheel. It is very hard to insert band rubber into nail hole on flat tire. The present invented barrel formed bolt, such as barrel-formed screw or barrel formed nail can be easily screwed or hammered into nail hole of a flat tire on wheel.
THE BRIEF SUMMARY OF THE INVENTION
Barrel formed bolt, such as barrel formed screw or barrel formed nail, can be easily screwed or hammered into a nail hole of a flat tire to stop air leakage. User must apply super glue to lubricate the barrel-formed screw or nail to facilitate the insertion and to create an airtight seal. There is no chance for barrel formed screw or nail to get loose because of the form of barrel formed screw or nail and adhesion of super glue. Barrel formed screw, barrel formed nail, super glue and screw driver come in a kit.

FIG. 2 is a perspective view of a barrel formed nail.
THE DETAILED DESCRIPTION OF THE INVENTION
Referring now in detail to the drawings, numeral 10 of FIG. 1 is barrel-form screw Numeral 11 of FIG. 1 is cap of barrel formed screw 10. Numeral 12 of FIG. 1 is cross-shaped groove on the top of cap 11. Numeral 13 of FIG. 1 is barrel formed screw body of barrel formed screw 10. Numeral 14 of FIG. 2 is barrel formed nail. Numeral 15 of FIG. 2 is nail cap of-barrel formed nail 14. Numeral 16 of FIG. 2 is cross-shaped groove on the top of nail cap 15. Numeral 17 of FIG. 2 is barrel formed nail body of barrel formed nail 14. Before the insertion of barrel formed screw 10 or barrel formed nail 14 into nail hole of flat tire user has to apply super glue to barrel formed screw 10 or barrel formed nail 14 for lubrication to facilitate the insertion and to create an airtight sealing. Because of the form of barrel of barrel formed screw 10 or barrel formed nail 14 and the adhesion of super glue it is very hard for barrel formed screw 10 or barrel formed nail 14 to come loose. By driving car forward or backward slowly inch by inch one can turn nail hole on flat tire to face the back of car. Once turning nail hole on a flat tire to face the back of car user lubricates the barrel formed screw 10 or barrel formed nail 14 with super glue and inserts or hammers it into nail hole of flat tire while it is on wheel After the insertion of barrel formed screw 10 or barrel formed nail 14, user has to wait for a couple of minutes to let super glue set before he/she inflates the repaired flat tire. A flat tire repair kit contains a barrel formed screw, a barrel formed nail, a tube of super glue and a screw driver. Barrel formed bolt is of a variety of size.
