SOCKET BIT HEX 1/2" 14MM L100MM

Item No:MP04397

 

SOCKET BIT HEX 1/2"14MM L100MM is a socket socket wrench accessory, where" 1/2"" represents a 1/2-inch driving tool (such as ratchet wrench, electric wrench),"14MM" is the opposite side size of the socket socket hole, and "L100MM" represents the sleeve length. Its core function is to tighten or remove 14MM socket screws/bolts. It is mainly used in heavy scenes such as industrial, machinery, and automobiles that require large torque and deep hole operations. The following is a detailed description:

 

Core function: high-strength hexagon socket bolt operation

The 14MM socket hexagon bolt is a larger size and is often used for connections that require high tightening force (such as high-strength bolts above level 8.8). The sleeve transmits large torque through a 1/2-inch drive interface. It is combined with professional tools to prevent bolts from slipping or breaking. It is suitable for the disassembly and maintenance of heavy equipment.

 

 

typical application scenarios

1. Automobile and construction machinery maintenance

Engine and chassis: Engine block bolts, differential fixing screws, and suspension system main pin bolts (such as leaf spring fixing) of trucks, excavators and other construction machinery often use 14mm socket hexagon bolts, and large torque tools are required to ensure a stable connection.

Tire and brake system: The wheel hub screws and disc brake caliper fixing bolts of some heavy vehicles adopt an inner hexagonal design, and the 14MM specification is suitable for the disassembly and disassembly of medium size wheels.

 

2. Industrial equipment and steel structure assembly

Heavy machinery installation: Mold fixing bolts for injection molding machines and punching machines, and large motor base bolts (such as 14mm internal hexagon) need to be matched with hydraulic or electric wrenches to achieve precise torque control (such as the recommended torque is about 50-80N·m, adjusted according to the material).

Steel structure engineering: Connections for bridges and factory trusses (such as high-strength bolt connections), 14MM internal hexagon bolts are used for node fixation with moderate load, and the 100MM length of the sleeve can be operated deep into the sandwich of the steel frame.

 

3. Agricultural machinery and ship maintenance

Agricultural machinery: The gearbox gearbox of tractors and the fixing bolt of the cutting device of combine harvesters often use the 14MM internal hexagon size to adapt to the high-intensity vibration environment during field operations.

Ship parts: Fixing bolts for engine accessories (such as water pumps, oil pumps) and deck equipment (such as winch bases) of small and medium-sized ships require anti-corrosion sleeves (such as nickel-plated materials) to be used together.

 

4. energy and infrastructure

Power equipment: Fixing bolts for high-voltage switchgear and transformer brackets in the substation. The 14MM inner hexagonal design can resist vibration caused by strong current. The sleeve supports rapid disassembly and disassembly of power tools.

Pipeline engineering: Fixing bolts for natural gas pipeline valves and industrial pipeline flanges (some use internal hexagons), with a length of 100mm suitable for operation in narrow pipeline wells.

 

Tool characteristics and usage advantages

High torque output of 1/2-inch drive: Compatible with industrial-grade driving tools (such as pneumatic impact wrenches), it can easily cope with high-strength bolts (such as level 10.9 bolt pre-tightening force requirements), and the length of 100mm can also provide sufficient force arm when manually operated.

 

Adaptability for deep holes: The length of 100mm is suitable for scenarios where bolts are installed in deep holes or depressions (such as when the depth of the screw holes in the engine block exceeds 50mm) to avoid inconvenient operation due to too short sleeves.

 

Anti-slip and wear-resistant design: The inner hexagonal hole is tightly engaged with the bolt head. The material is mostly CR-V chromium-vanadium steel or S2 tool steel. The surface is quenched, which is wear-resistant and impact-resistant, suitable for frequent disassembly and assembly.

 

 

precautions for use

Strictly match the specifications: 14MM inner hexagon bolts and 1/2-inch outer hexagon bolts (corresponding to 14MM sleeves) need to be distinguished to avoid confusion that may cause tool damage or bolt slippage (the head of the inner hexagon bolts is a hexagonal groove, and the outer hexagon is a raised prism).

 

Key to torque control: When using power tools, the torque must be set according to the bolt strength level (for example, the recommended torque for 14MM and 8.8 bolts is about 70-90N·m). Overload may cause the bolt to break (especially on soft substrates such as aluminum alloy).).

 

Rust prevention and maintenance: After long-term use, check the wear of the inner hole (such as corners and corners that need to be replaced when rounded). Avoid humid environment during storage, and apply anti-rust oil to extend life.

 

 

 

 

 

 

Thanks to its characteristics of "large size socket hexagon + 1/2 inch strong drive + moderate length", this tool has become an indispensable tool for processing 14mm socket hexagon bolts in heavy machinery and industrial engineering. It is especially suitable for those requiring high reliability and efficiency. Disassembly and assembly scenarios.
