In the field of maintenance, the sleeve is an indispensable tool. Whether it is a professional mechanic or a home user who loves DIY, they need to understand the various functions of the sleeve and how to purchase it correctly.

First, let's uncover the mystery of the sleeve family! From the most basic standard model to the high-end custom version, each sleeve has its own unique use and characteristics. For example, the common hexagon socket is suitable for most common bolt connections; while the twelve-angle design increases the contact area, which is especially suitable for operating environments with small spaces.

Next, let's talk about the choice of materials. There are three common materials in the mainstream market-stainless steel, chrome vanadium steel and titanium alloy. Among them:
stainless steel sleeve has strong corrosion resistance but slightly inferior hardness;
chrome vanadium steel takes into account both strength and toughness, and has extremely high cost performance.
as for the higher grade titanium alloy, it is light in weight and durable, but the price is relatively high.

So what specific scenarios need to use what kind of sleeve? In car maintenance, we often need to face complex and diverse screw specifications, so it is recommended to equip a complete set of suit; for simple home repair work, a few commonly used fixed dimensions are sufficient to meet daily needs. In addition, special tools of specific types are frequently used in areas such as installation and commissioning of garden trimming equipment.

In addition to paying attention to performance parameters, what should not be ignored is the consideration of ergonomics-whether the design of the grip is scientific or not directly affects the fatigue degree of long-term use. Modern high-quality brands generally adopt soft rubber wrapping technology to make the hand feel soft and non-slip while buffering the impact force to protect the health of the joints of hands.

of course, there are some hidden but very practical functions worth paying attention to: for example, the built-in magnet can firmly attract small parts to prevent them from being lost; In addition, the adjustable angle joint allows you to complete the fastening action at any tricky angle, etc. These are all good helpers to improve efficiency!

finally, I would like to give some warm tips to new friends who purchase for the first time: be sure to make clear your main application direction and then select the appropriate model range accordingly; At the same time, check the packing list to confirm whether there are complete accessories (such as extension rod quick disassembler, etc.); The most important thing is to try to choose reputable merchants to ensure reliable product quality.

The practical experience of many old users tells us that the correct maintenance method can significantly extend the life of the cylinder. Regular cleaning of residual dirt and lubricating oil to reduce friction loss are simple and effective measures.
