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

This scratch is currently invisible because it is covered by the hot and cold symbols or hidden under the handle So let&# 039; S brief talk about the hot and cold symbols first

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 effects: one is the prompt effect, which shows the direction of cold water and hot water; Another method is to create a decoration effect, which can block the raw holes So the first step in replacing the valve core of the faucet is to remove the hot and cold symbol first

Removing this hot and cold symbol is the first step in removing the handle

The main effect of locking the screen is to firmly fix the handle onto the valve core of the faucet, preventing it from changing over time Why do some faucets appear loose and collapsed when the faucet handle is opened after not being used for long And some won&# 039; Loosen? There are three factors that can cause the handle to loose

1: Valve core elements; The quality of the valve core used by the faucet is not up to standard, and after some time of use, the valve core is frequently worn, causing the gap to become larger;

2: Handle elements; The tear on the handle lakes uses valid 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 simple terms, is the lake of thickness at the scratch position on the handle, which is too thin As long as the thread has only two circles of pattern tea, it cannot stand it for a long time

Another issue is that the square hole on the handle and the square valve stem on the valve core do not cooperate properly, which is too loose Thereforee, every time the faucet is turned on or off, it is fundamentally born equitably by the locking thread on the handle

This situation basically occurs on handles made of zinc alloy materials because zinc alloy materials have a soft texture and are prone to corrosion, specifically when faucets are used in high humidity environments

The handle made of brass material basically does not exhibit this phenomenon, but the cost of the handle made of copper material is too high and it is urgently used

3: Elements of locking screws

After a lot of verbosity, it&# 039; Finally, my turn to elaborate on the locking screws

The general thread specification for locking screws is M5, which means that the diameter of the screw is 5 millimeters

There is a difference between iron and stainless steel in the information The locking screws of iron are commonly blackened on the surface to prevent them from rotting later

Locking tools are used to differentiate between flat, cross, and hexagonal

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