The locking screw of the handle of a faucet is a small metal component among many components of the faucet

This screw is visually invisible, as it is masked by hot and cold symbols or hidden under the handle So let; S brief talk about the symbols for hot and cold

The hot and cold symbol refers to a small decorative component installed on the handle There are both metal and plastic This symbol has two main functions: one is to indicate the direction of the location of cold and hot water; Another type is for decorative purposes, which can block the screw holes So to replace the valve core of the faucet, you need to first remove this hot and cold symbol

Removing this hot and cold symbol is removing the handle

The main function of the locking screw is to firmly fix the handle onto the valve core of the faucet, preventing it from changing over time Why do some faucets experience loss and collapse when the faucet handle is open after not being used for long And some won; T Loosen? There are three factors that can cause the handle to loose

1: Valve core elements; The quality of the valve core used in the faucet is not up to standard, and after some time of use, the valve core wears severity, causing the gap to increase;

2: Handle elements; The screws on the handle have missing threads and the operation between the square hole on the handle and the valve core rod is too loose

The lake of effective threads, in layman# 039; S terms, refer to the lake of thickness at the screw position on the handle, which is too thin The thread only needs two circles of grooves, and over time, it cannot be accepted

Another issue is that the square hole on the handle does not cooperate properly with the square valve stem on the valve core, which is too loose Therefore, every time the faucet is turned on or off, it is usually fairly accepted by the locking thread on the handle

This situation basically occurs on handles made of zinc alloy materials Due to the soft texture of zinc alloy materials and their susceptibility to corrosion, faucets are used in high humidity environments

The handle made of brass material basically does not exhibit this phenomenon, but the handle made of copper material has a high cost and is less commonly used

3: The elements of locking screws

After talking a lot, it# 039; S finally time to go into detail about the locking screws

The thread standard for locking screws is generally M5, which means the diameter of the screw is 5 millimeters

There is a difference between iron and stainless steel in materials, and iron locking screws are generally treated with blackening on the surface, with the intention of causing the screws to rot later

Lock things to differentiate between those with a single character, a cross, and an inner hexagon

From the perspective of the locking end structure, there are flat, pointed, and concave pointed ends
