Hex Key Socket 1.1/2 in, Bondhus BO12229, Length 336 mm

Bondhus BO12229 is a 1.1/2-inch hex key socket with a length of 336 mm designed for driving large internal-hex fasteners. The tool provides a precise hex fit for efficient torque transfer and accurate alignment of hex-headed components. Its extended length improves reach into recessed or obstructed fasteners, making it suitable for workshop and industrial environments where larger fasteners and limited access are common.

Advantages

The hex key socket delivers a secure internal engagement that reduces rounding and slippage when applying high torque. Its long reach simplifies access to deep-set or recessed fasteners without requiring adapters or extensions. Manufactured to tight dimensional tolerances, the socket ensures consistent fit and repeatable performance on large hex fasteners. The straight-through design allows for use with compatible torque tools and drivetrains, enabling controlled torque application.

Suitable for

• Driving large 1.1/2-inch internal-hex fasteners in industrial assembly
• Accessing recessed or deep-set bolts in machinery and equipment
• Workshop maintenance and heavy-duty repair tasks
• Applications requiring precise torque transfer and alignment

Key specifications

• Internal hex size: 1.1/2 inch
• Overall length: 336 mm
• Type: Hex key socket (internal drive)
• Intended use: Drive large internal-hex fasteners and bolts
• Compatibility: Designed for use with appropriate drive tools and torque wrenches

How to use

Select a compatible drive tool and ensure the socket is fully seated on the fastener before applying torque. Insert the hex key socket into the drive tool and position the hex end into the internal-hex fastener, verifying full engagement of all faces. Apply torque smoothly and steadily, observing the required torque specification for the fastener material and assembly. After use, inspect the socket for wear or deformation and clean any debris before storage.

Usage recommendations

Use the 336 mm length socket for reach-critical applications and combine it with torque-controlled tools when precise torque values are required. Avoid excessive impact loading and replace the socket if signs of rounding or cracking appear to maintain safe and reliable operation.
