There are many types of rivets, which are divided according to their use: hollow, solid, semi-hollow, core-pulling, core-punching, etc. The geographical restrictions also produce names in many places, but in terms of specifications, they should be detailed: head shape Diameter * Head thickness * Tube diameter * Length (excluding head thickness) * Aperture * Hole depth. Normally, the aperture and depth have been omitted. If you do not have drawings or pictures, you should include these elements. By telling the material again, it can basically be produced directly.

Hollow rivets are usually used in clothing, footwear and other industries. They need to be riveted again. They are used for heavy workpiece joints. They are often unremovable structures. Semi-tubular rivets are the most widely used. The bundles (small diameter tails) are hard wire. It can be manufactured without the need for pre-holes to penetrate the steel plate with a thickness of 0.5mm. The rivets can not be bent and deformed. They are widely used in lock boxes, suitcases and military bags. Hollow nails (semi-tubular rivets) are made of soft wire and generally require riveting. After cracking, there are many types. At present, the shafts on some toys have begun to be replaced by semi-hollow nails or sub-nails in a large area, which can greatly reduce the production cost. The core pulling and core rivets are mostly used for riveting of relatively thin soft materials. Generally, the requirements are not strict, and the manufacturing materials are usually produced by using a plastic material.
