The nail rod of the coiled nail handles the split rod, thread, ring pattern, etc., the polished rod is easy to disassemble, the thread is suitable for the connection of hardwood, and the ring pattern is suitable for the connection of softwood.

　　1. The surface treatment of coil nails is divided into dipping paint, galvanizing, color zinc plating, dacromet, etc. Generally, only dipping paint is used in China. The uniformity of dipping paint has a direct impact on the effect of lubrication, tightening and rust prevention. .

　　2. 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 is, 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;

　　3. The matching of the nail gun and the coil nails should be good. The design of the nail gun has certain requirements on the angle and nail distance of the coil nails. The compatibility of large nails is good. For nails with wire diameters below 2.3, you must first know what to use. Whether the nail gun matches the nail.

　　4. 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 joint is clean and tidy, and the poor welding wire is easy to deform and break during use, causing the nail to be stuck.

　　5. You must be careful 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 made. 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 nails one size smaller.
