In daily life, wrenches are not unfamiliar to us, so what are they and how should we use them? Let the hardwaretools.comc website tell you!
- Double headed wrench:
Purpose: To tighten or remove hexagonal bolts, nuts, and square bolts and nuts. Safe usage rules:
When using, the wrench should be kept level with the plane of the bolt and bolt hexagon or nut 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.
Metric wrenches should not be used for metric bolts or nuts, nor should they be used for metric bolts or nuts to avoid slipping and injuring the user. - Double headed plum blossom wrench:
Purpose: To tighten or remove hexagonal head bolts or nuts
Features: The plum blossom wrench made of Crv steel is sturdy and durable, with a torque 10% -20% higher than ordinary alloy steel plum blossom wrenches and 30% -100% higher than carbon steel plum blossom wrenches.
The twelve corner holes of the Crv steel plum blossom wrench are machined by push cutting, with high hole shape accuracy.
Accurate twelve corner indexing ensures even force distribution at the six corners of the nut without damage.
The neck of the plum blossom wrench adopts a bending design of 15 degrees to 45 degrees, which can tighten the bolts or nuts in the groove area, and is not easy to hurt hands during use. Safe usage rules:
Metric wrenches should not be used for metric bolts or nuts, nor should they be used for metric bolts or nuts to avoid slipping and injuring 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. - Dual purpose wrench:
Purpose: To tighten or remove hexagonal bolts or nuts and square 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, while the torque at the plum blossom 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 tightening angle without having to remove it from the hex nut. Safe usage rules:
Metric wrenches should not be used for metric bolts or nuts, nor should they be used for metric bolts or nuts to avoid slipping and injuring 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 - Active wrench:
Purpose: To tighten or remove hexagonal bolts, nuts, and square bolts or nuts.
Features: The “FEITA Non Thai” adjustable wrench is made of high manganese steel, while the “FEITA Non Thai” adjustable wrench is made of CR-V steel.
The adjustable wrench made of Crv has a torque that is more than 20% higher than that of a regular adjustable wrench.
The movable wrench and wrench body are precisely matched, with small gaps that are not easy to loosen or slip, making adjustment smoother.
The thickened handle feels good when used, and the “FEITA Non Thai Brand” wrench is coated with sandding nickel as a 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 in use, bolts or nuts 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. - Hexagonal wrench:
Purpose: To tighten or remove 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 metric screws, nor should you use metric hex wrenches for metric screws to avoid slipping and injuring the user.
Do not add a sleeve extension arm to 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 it is highly susceptible to damage under impact loads. - Socket wrench:
A socket wrench is composed of multiple sockets with hexagonal or twelve pointed holes, and is equipped with various accessories such as handles and extension rods. It is particularly suitable for turning bolts or nuts with very narrow or deeply recessed positions.
If the nut end or bolt end is 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, a socket wrench should be used. In addition, due to space limitations of bolt components, only socket wrenches can be used. - Multi functional wrench:
Nowadays, there are various types of bolts, which makes it inconvenient for us to prepare multiple wrenches when disassembling. Now, Dongguan Feitai Electronics Co., Ltd. has launched a new “multifunctional wrench”, also known as a multifunctional adjustable wrench. Its main feature is that it can be used for multiple purposes, and various parts can be disassembled and installed. It is easy to use, efficient, sturdy and reliable, lightweight and easy to carry. 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 small spaces and can automatically match various nuts. Water pipes, screws, round, square, diamond shaped and other 6-32mm can be tightened. It can be used for water and electricity maintenance, home appliance maintenance, with one set in hand, everything can be done!
A new type of multifunctional wrench, which consists of a socket with two inner corners, a column, gears, a pin shaft, a spring, a ball, teeth, a spring card, a flat screwdriver, and sockets with two inner corners of different sizes. It is composed of a wrench matched with sockets of different diameters as one set, and the other end of the wrench can be designed as a flat mouth. Its structure is simple, easy to manufacture, and easy to operate, saving time and effort, achieving the goal of a tool with multiple uses.
