In daily life, wrenches are not unfamiliar to us, so what are they and how to use them? Let FEITA electronic tools tell you!
1. Double headed solid wrench:
Usage: Tighten or disassemble hexagonal head bolts, nuts, and square head bolts and nuts. Safe usage rules:
When using, the wrench should be kept level with the plane between the bolt and the hexagonal head or nut of the bolt to prevent the wrench from slipping out and injuring people when applying force.
Do not add a sleeve to extend the force arm at the end of the wrench to prevent damage to the wrench.
Do not use a steel hammer to strike the wrench, as the wrench is prone to deformation or damage under impact loads.
Do not use metric wrenches on imperial bolts or nuts, nor do you use imperial wrenches on metric bolts or nuts to prevent slipping and injury to the user.
2. Double ended box wrench:
Usage: Tighten or disassemble hexagonal head bolts or nuts
Features: The ring wrench made of Crv steel is sturdy and durable, with a torque 10% -20% higher than ordinary alloy steel ring wrenches and 30% -100% higher than carbon steel ring wrenches.
The twelve corner holes of the Crv steel ring wrench are machined by push machining, with high accuracy in hole shape.
The precise twelve degree division ensures that the six corners of the nut are uniformly stressed and not damaged.
The neck of the ring wrench adopts a bending design of 15 to 45 degrees, which can be used to tighten bolts or nuts in the groove area, making it less prone to hand injury during use. Safe usage rules:
Do not use metric wrenches on imperial bolts or nuts, nor do you use imperial wrenches on metric bolts or nuts to prevent slipping and injury to the user.
Do not add a sleeve to extend the force arm at the end of the wrench to prevent damage to the wrench.
Do not use a steel hammer to strike the wrench, as the wrench is prone to deformation or damage under impact loads.
3. Dual purpose wrench:
Usage: Tighten or disassemble hexagonal head bolts or nuts and square head bolts or nuts.
Features: The dual-purpose wrench made of Crv steel is sturdy and durable. The torque at the open end is more than 100% higher than that of carbon steel wrenches, the torque at the plum end is 10% -20% higher than that of ordinary alloy steel wrenches, and 30% -100% higher than that of carbon steel wrenches.
The special opening of the quick dual-use wrench allows the wrench to change the turning angle without having to be removed from the hex nut. Safe usage rules:
Do not use metric wrenches on imperial bolts or nuts, nor do you use imperial wrenches on metric bolts or nuts to prevent slipping and injury to the user.
Do not add a sleeve to extend the force arm at the end of the wrench to prevent damage to the wrench.
Do not use a steel hammer to strike the wrench as it is prone to deformation or damage under impact loads
4. Monkey wrench:
Usage: Tighten or disassemble hexagonal head bolts, nuts, and square head bolts or nuts.
Features: The “FEITA Non Thai” wrench is made of high manganese steel, while the “FEITA Non Thai” wrench is made of CR-V steel.
The torque of the adjustable wrench made of Crv is more than 20% higher than that of a general adjustable wrench.
The combination of the movable trigger and the trigger body is precise, with a small gap that is not easy to loosen or slip, and the adjustment is smoother.
The thickened handle has a good hand feel when used, and the “FEITA Non Thai Brand” wrench is coated with sanding nickel on the whole, which is beautiful and has good rust resistance.
When using, the size of the wrench must be adjusted accurately to prevent loosening and slipping.
When using, the bolt or nut should be tightened in the forward direction.
Do not add a sleeve to extend the force arm at the end of the wrench to prevent damage to the wrench.
Do not use a steel hammer to strike the wrench, as the wrench is prone to deformation or damage under impact loads.
5. Internal hexagonal wrench:
Usage: Tighten or disassemble hexagon socket head screws and set screws. Mainly used for assembly and maintenance work in industries such as mechanical manufacturing, automobiles, engines, and agricultural machinery. Safe usage rules:
Do not use metric hex wrenches for imperial screws, nor do you use metric hex wrenches for metric screws to prevent slipping and injury to the user.
Do not add a sleeve to extend the force arm at the end of the hex wrench to prevent damage to the hex wrench.
Do not use a steel hammer to strike the hex wrench, as the hex wrench is easily damaged under impact load.
6. Socket wrench:
A socket wrench is composed of multiple sockets with hexagonal or hexagonal holes and equipped with various accessories such as handles and extension rods. It is particularly suitable for turning bolts or nuts with very narrow positions or deep depressions.
For nut or bolt ends that are completely lower than the connected surface, and the diameter of the concave hole cannot be used for open end wrenches, adjustable wrenches, and ring wrenches, use a socket wrench. In addition, due to space limitations of bolt components, only a socket wrench can be used.
7. Multi functional wrench:
Nowadays, there are various types of bolts, which makes it inconvenient for us to prepare multiple wrenches for disassembly. Now, Dongguan Feitai Electronics Co., Ltd. has launched a new “multifunctional wrench”, also known as a multi-functional adjustable wrench. Its main feature is that it can be disassembled and installed with various parts, making it easy to use, efficient, sturdy, reliable, lightweight, and portable. Someone may ask, how to use a multifunctional wrench? There are two sets of universal wrenches, one small wrench is 210mm long and the other large wrench is 32mm long. They can be used in narrow spaces and can automatically match various nuts. Water pipes, screws, round, square, diamond, etc. can all be tightened by 6-32mm. Water and electricity maintenance, home appliance maintenance, a set in hand, everything is done!
A new type of multifunctional wrench, which is composed of a socket with two internal corners, a sleeve column, a gear, a pin shaft, a spring, a ball, a snap tooth, a spring card, a flat screwdriver, and sockets with two internal corners of different sizes. It consists of a set of wrenches with different caliber sockets, and the other end of the wrench can be designed as a flat end. Its structure is simple, easy to manufacture, and easy to operate, saving time and effort, achieving the goal of a tool with multiple uses.
