The nail rod treatment of coil nails is divided into smooth, screw and ring.

The nail heads of the coil nails are pointed, blunt, chisel point, blunt chisel, etc., which are determined according to the hardness and toughness of the material. Generally, only pointed ends are used in China. Most coil nail users mistakenly believe that the sharper the nail, the better. This concept is wrong. Any nail has its special application occasions. It should be determined according to the specific situation. This has a certain relationship with the nail gun and the material.

The matching of nail gun and coil nails should be good. The design of nail gun has certain requirements on the angle and nail distance of coil nails. The compatibility of large nails is good. For nails with wire diameters below 2.3, you must first know the nail gun used. Does it match the nail.

The welding wire of coiled nails is very important. The hardness and toughness of the good welding wire are just right, the appearance of the welding spot is clean and tidy, and the poor welding wire is easy to deform and break during use, causing the nail to be stuck.

You must be cautious when choosing nails. Nails with non-standard spot welding spacing will seriously affect the life and work efficiency of the nail gun. In addition, you must pay attention to the traps in the purchase. In order to reduce costs, many nail manufacturers cut corners and make the wire diameter thin and the nails short. Consumers are the last losers. When buying nails, they must use a vernier caliper to measure and weigh them. The size and weight of the nails must be consistent with the logo on the outer packaging. Otherwise, it is cheaper to buy a smaller nail.
