Shandong Chuanxiang Machinery Manufacturing Co., Ltd. is a manufacturer integrating development, production and marketing, mainly producing auto parts and facilities. Since its establishment, the company has always adhered to the fundamental principle of product development according to customer needs; the idea of establishing an enterprise with science and technology; Talent-oriented, Seek Truth and Be Pragmatic, keep improving, relying on advanced production equipment and technical strength for customs clearance; strict production management and quality control as a guarantee.

Hex bolts

Hexagon bolt is a metal fitting, also known as hexagon screws, hexagon screws or hexagon bolts.

Cross recessed countersunk head screw

Cross groove countersunk head screw is a kind of screw, the head is flat head, countersunk head, or half countersunk head. Countersunk head screws can also be called flat head screws, countersunk head screws, half countersunk head screws, half countersunk head screws. General countersunk head screws are cross grooved.

Flat pad

The flat pad is mainly stamped out of an iron plate. The shape is generally a flat gasket with a hole in the middle. There is a calculation formula in the "Quality Encyclopedia of Standard Fasteners" published by China Standard Publishing House. The formula is: weight of one thousand pieces m = 0.00785 × {3.1416/4 × Washer height × [square of outer diameter - square of inner hole diameter]

Hexagon socket head bolt

Cylindrical head hexagonal screws, also referred to as hexagonal bolts, cup head screws, hexagonal screws, have different names, but the meaning is the same. Generally used hexagonal head screws are also grade 4.8, grade 8.8, grade 10.9, and grade 12.9. Also called hexagonal screws, also called hexagonal bolts. The head is hexagonal head, and it is also cylindrical head. According to the material, it is divided into stainless steel and iron.

Hex nut

Hexagonal nuts are also called hexagonal nuts. Generally, there are many types of nuts, including hexagonal nuts, round nuts, square nuts, etc. Some standards for nuts are still relatively clear. Some specifications and size standards, material requirements standards, electroplating standards, etc. are relatively clear. And different types of nuts also have different standards. Introduce the specifications and standards of nuts in detail.

Tight top (the hex flat head is tight, the tip is tight and the hex tip is tight)

The inner hexagon screws are beautiful, and the nuts are not directional, unlike the outer hexagon bolts. For example, there are multiple bolt heads exposed on the table. If the direction of his head is not unified, it will feel messy, and the inner hexagon feels very neat.

Locknut

Anti-loosening nuts and self-tightening nuts are common fastening anti-loosening nuts. Including mechanical anti-loosening, riveting anti-loosening, friction anti-loosening, structural anti-loosening, etc.

Spring pad

The elastic pad is widely used in the load-bearing and non-load-bearing structures of general mechanical products. It is characterized by low cost, convenient installation, and is suitable for parts with frequent assembly and disassembly.

Large flat head (with pad) self-tapping

Self-tapping screws are used for non-metallic materials or too soft metal materials, without inner holes and tapping; self-tapping screws are pointed, so that they can be "self-tapping"; ordinary screws are all round heads and the size is the same. Self-tapping screws mean that the drilled hole is a hole that does not need to be tapped, and the screws used are different from the general ones. The head is long and pointed, and the tooth distance is relatively large, which is somewhat similar to a chip-free tap. You can screw in immediately without tapping. Metal materials and plastics usually use these methods.
