Screws and nuts are more common hardware accessories in our lives, which can be seen in many occasions. Nut is the nut, and bolts or screws screwed together used to play a fastening role in the parts, divided into carbon steel, high strength, stainless steel, plastic steel and other major types. Screw is just a general statement of fasteners, then the screw nut bite dead how to do it? This article is a brief introduction!

A, screw nut introduction

Screw nut is a unified whole, the nut is a screw in an accessory, screws include: bolts, screws, nuts, as long as there is a threaded fastener bolts by the head and screw two parts of a class of fasteners, need to cooperate with the nut, used to fasten the connection of two parts with a through hole. Nut with internal threaded holes, the shape is generally shown as a flat hexagonal column, there are flat square or flat cylindrical, with bolts, studs or machine screws, used to fasten the connection between the two parts, so that it becomes a whole piece.

Two, screws and nuts bite dead how to do

This is often encountered in our lives, bite dead often occur in stainless steel, alloy materials screws, nuts, is because when the fasteners are tightened, the pressure on the threaded surfaces in contact with the destruction of the oxide film, the loss of the oxide film of the metal contact will occur peeling off and produce each other to bite tightly; we need to use a professional Lubrication equipment for coating after to solve this problem.

Three, link type

Screw nut big link in our life has many types, can be divided into three main. Non-removable - this is a use of welding, bonding or punching point riveting and other removable threaded connections to change to non-removable threaded connections of the anti-loosening method is commonly used in some of the requirements of the anti-loosening of the important occasions of high reliability and does not need to be disassembled; Mechanical fixing - the use of mechanical fixing pieces to make the threaded parts and the connection between or between threaded parts and the threaded pieces fixed and Mechanical fixing - the use of mechanical fixing parts to make between the threaded parts and the connected parts or between the threaded parts and the threaded parts are fixed and pinned tightly to stop loosening; increasing friction - the use of increasing the friction between the threads or the end face of the screws and nuts or increasing the friction between the two at the same time to achieve the purpose of locking.

The above is about the relevant content of the screw nut, I hope it can help you!
