Trident Wrench

BOSI brand three-pronged Trident Wrenches from China are made of high-quality 40Cr alloy steel. The socket heads are heat-treated for high hardness and wear resistance. The unique Y-shaped three-pronged design integrates three different socket sizes into one unit, and the torque-enhancing hexagonal tail can be used with other wrenches for additional torque.

They are available in five combinations: 8-9-10mm, 8-10-12mm, 10-12-14mm, 12-14-17mm, and 14-17-19mm, all with a length of 140mm. This wrench conforms to standards GB/T3390.1 (sockets) and GB/T3390.2 (transmission accessories). It is suitable for quick assembly and disassembly of hexagonal head bolts and nuts in automotive repair, mechanical assembly, and home emergencies.

Product Specifications

What is a Trident Wrench?

A Trident Wrench is a hand tool that integrates three different sized socket heads arranged in a Y-shape onto a single handle. Unlike a single socket wrench, it eliminates the need to change socket heads; simply rotate the handle to select the corresponding size, making it suitable for quick operations.

This BOSI three-pronged wrench is forged from 40Cr alloy steel, with a heat-treated head to ensure the precision and hardness of the socket's inner bore. The tail has an external hexagonal design; when greater torque is required, another wrench can be used to hold the tail for additional force.

Its compact size (only 140mm in length) allows it to fit in a vehicle tool bag or a household drawer. It is used for assembling and disassembling common-sized nuts and bolts, and is especially suitable for emergency automotive repair, motorcycle maintenance, and furniture assembly.

Packaging and Shipping

The packaging box of BOSI Trident Wrench is made of thickened corrugated paper, and the quantity of each box varies according to the specifications (80 or 60 pieces). Separate the box to prevent mutual friction. Suitable for retail in supermarkets and hardware stores.

Attach a certificate of conformity before shipment. Due to its small size and light weight, it is suitable for express delivery. Please consult customer service for packaging size and weight details.

FAQ

Q: How to distinguish the three specifications of a Trident Wrench? 

A: Each fork arm is engraved with a specification number (e.g., 8, 9, 10). When using, simply slip the corresponding socket onto the nut and turn the handle.

Q: How to apply force to the outer hexagon of the tail? 

A: Clamp another open-end wrench or adjustable wrench onto the hexagonal head at the end, and turn the torque-enhancing wrench to increase the torque. This is suitable for removing rusty or overtight nuts.

Q: What should I do if the sleeve is worn and slipping inside? 

A: 40Cr has high hardness after heat treatment and is not easily worn under normal use. If slippage occurs, the nut may be deformed or an incorrect size may be used. If the socket is indeed worn after inspection, a new wrench needs to be replaced.

Q: Can it be used for impact wrenches? 

A: No. A three-pronged wrench is a manual tool and cannot withstand impact loads.

Q: How to choose the appropriate combination of specifications? 

A: 10-12-14mm is commonly used in automobiles, 8-10-12mm in motorcycles, and 12-14-17mm or 14-17-19mm for heavy machinery. Choose according to the commonly used nut size.
