Fasteners are the most widely used mechanical basic objects, and the inspection and distribution methods are also different. Of course, the most important thing is quality control. After all, quality is the most important criterion to measure whether an object is qualified. Then, the first thing related to quality is appearance, size, impact test, forging streamline; the appearance after heat treatment, hardness, torque, tension and gold content are higher. Heat treatment involves more appearance, hardness, torque, tensile force, metallography, etc. Surface treatment involves more hydrogen embrittlement testing, electroplating, salt spray, etc., including testing of harmful substances during transportation.

It usually includes the following 13 types of parts: bolts, studs, screws, nuts, self-tapping screws, wood screws, washers, retaining rings, pins, rivets, components and connection pairs, welding nails, wire thread inserts.
