Fast wrench 72T (torque super German standard)/Socket head CRV (50BV30)/Pliers wrench 45# Heat treated high carbon steel/Screwdriver hex head CRV (6150)

 

1. Speed wrench 72T (torque exceeds German standard)

 

core features

72-tooth design: High gear density, small rotation angle (only 5°) can complete one bite, suitable for operation in small spaces.

Torque exceeding German standards: The torque intensity is higher than German industrial standards (such as DIN), can withstand greater pulling force or thrust, and is not easy to slip or break.

 

Function and purpose

Tighten/remove bolts and nuts

It is suitable for car maintenance, mechanical assembly, construction and other scenarios, especially in situations where high-frequency and rapid screwing is required (such as chassis screws and engine parts). The efficiency is about 50% higher than that of ordinary wrenches.

 

The ultra-standard torque design can deal with high-strength bolts (such as steel structural connections and heavy equipment fixation) and avoid loosening due to insufficient torque or damage to wrenches due to overload.

 

Working in tight spaces

The compact structure of 72 teeth allows the wrench to turn quickly in limited spaces (such as engine compartments, pipe gaps) without the need to adjust the wrench angle frequently.

 

2. CRV sleeve head (50BV30 material)

material properties

50BV30 steel: Carbon content is about 0.5%, and boron (B) and vanadium (V) are added. Its hardness (HRC45-55), toughness and wear resistance are better than ordinary carbon steel, and it has strong impact resistance.

 

Function and purpose

Adapt to various bolt heads

The shape of the inner hole of the sleeve head accurately matches the bolt head (hexagonal, twelfth, etc.) to avoid slipping and damaging the bolt. It is often used for automobile tire replacement, home appliance dismantling, industrial equipment maintenance, etc.

 

Use with wrench/ratchet wrench

It can be combined with speed wrenches and ratchet wrenches to amplify torque through the lever principle. It is suitable for tightening bolts in deep holes or hidden positions (such as gearbox screws, embedded wall parts).

 

Resistance to high-intensity operations

The 50BV30 material can withstand high torque operations and is not easy to deform or break. It is suitable for bolt disassembly and disassembly of heavy machinery (such as construction machinery and marine equipment).

 

3. Clamp wrench (45 #heat treated high-carbon steel)

material properties

45 #high-carbon steel: The carbon content is about 0.45%. After quenching + tempering heat treatment, the hardness (HRC40-45) and wear resistance are improved, and the jaws are not easy to crack.

 

Function and purpose

 

Clamping and fixing

Used to clamp round, hexagonal and other workpieces (such as water pipes, steel pipes, bolts), fix parts during pipe installation and mechanical maintenance to prevent slipping.

 

Torsion and removal

The opening size of the jaw can be adjusted to adapt to pipes or bolts of different diameters. It is especially suitable for tightening/removing rusty and slipping bolts (such as old equipment screws), which is more labor-saving than ordinary wrenches.

 

Cutting and bending

Some pliers wrenches have both shearing edges and can cut soft metals such as iron wire and copper wire, or bend small metal pieces (such as wire joints).

 

4. CRV hexagonal screwdriver (6150 material)

material properties

6150 steel: Carbon content is about 0.5%, chromium (Cr) and vanadium (V) are added, it has high hardness (HRC50-55) and strong fatigue resistance, and the screwdriver head is not easy to wear or collapse.

 

Function and purpose

Tighten/remove hex screws

Adapt to internal and external hexagonal bolts (such as furniture connectors, electronic equipment screws), especially in scenarios requiring precise torque control (such as precision instrument assembly), the 6150 material can reduce the risk of wire slippage.

 

multi-scene application

Electronic maintenance: Remove the inner hexagon screws of laptops, mobile phones and other equipment;

Furniture installation: Tighten the hexagonal connectors of tables, chairs, and wardrobes;

 

Industrial assembly: It is used for batch installation of hexagonal bolts in mechanical equipment and is resistant to high-frequency use.

 

5. The overall value of the 201-piece tool set

One-stop solution: It includes various types of tools such as wrenches, sockets, pliers, and screwdrivers, covering scenarios such as home maintenance, car maintenance, and industrial maintenance, without requiring separate purchase of a single tool.

 

Material durability: CRV steel, 45#heat-treated high-carbon steel and other materials ensure that tools are not easily damaged during long-term use, and are suitable for professionals or DIY enthusiasts.
