Summary of information:We have more than ten years of production experience in the screw industry, the main products are: column plastic stud, ...

Wood screws are similar to machine screws, but the thread on the screw is a special thread for wood screws, which can be directly screwed into wooden components (or parts) to connect a metal (or non-metal) part with a through hole to a wood screw. The components are fastened together. This connection is also a detachable connection.

The fastener with a nut is composed of a polygonal nut and a bolt. The bolt includes an integral screw rod and a screw head. The fastening surfaces of the nut and the screw head are polygonal. There are external threads on the periphery of the screw, and the main point is that the axial three-dimensional shape of the nut and the screw head is an odd-numbered truncated cone, and the odd-numbered angle is an arc angle, and each arc angle corresponds to an elastic surface.

In all kinds of machines and equipment, the various parts are fixed and assembled by bolts and nuts. However, after the machine and equipment are used for a period of time, the bolts and nuts will become loose, which will bring great safety hazards to the use of the machine and equipment. For this reason, when bolts and nuts are used for connection, a spring washer is installed between the nut and the connected part. The spring washer is in the shape of a circular ring, and the ring is not closed, and is sleeved on the bolt. The addition of the spring washer has a certain anti-loosening effect, but it can only prevent the nut from rotating relative to the bolt. In the case of large vibration of the machine, the bolt will rotate relative to the connected part.

Screw refers to a screw, which is a tool that uses the physical and mathematical principles of the inclined plane, circular rotation and friction of an object to gradually fasten objects and parts. A screw is a common term for fasteners. Fasteners are widely used in machinery, electrical appliances and buildings. They are generally made of metal or plastic, cylindrical in shape, and grooves engraved on the surface are called threads.

double-headed pin puller includes a slider hammer and a sliding rod, two ends of the sliding rod are respectively provided with different types of pin-pulling parts, the pin-pulling parts are threadedly connected with the sliding rod, and the sliding rod is also provided with There is a sliding rod limit block, and the sliding rod is slidably connected with the slider hammer. The double-headed pin puller can install two types of pin-pulling heads at the same time, and can pull out two different types of pins. It is easy to use and has high work efficiency. Disadvantage: Single function, cannot be used to install pins.

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: hardware boat nuts, saddle-shaped single-sided with pattern teeth, A483 hexagon nuts, chamfered hexagon socket head furniture bolts and other products, we can provide you with suitable products.
