Shop Enerpac hydraulic torque wrench Allen drives for controlled tightening and loosening of internal-hex fasteners. These accessories allow compatible Enerpac hydraulic torque wrench systems to apply high torque to socket-head bolts and other fasteners that require an internal hex drive.
Select the correct Allen drive by matching the accessory to the compatible torque wrench, drive configuration, and fastener hex size. Proper compatibility and full fastener engagement are essential for safe and accurate bolting.
Choosing an Enerpac Hydraulic Torque Wrench Allen Drive
Start with the hydraulic torque wrench model and series being used, then determine the internal hex size of the fastener. The Allen drive must be compatible with the wrench system and correctly sized for the fastener.
Match the Fastener Hex Size
The Allen drive must fit the internal hex of the fastener correctly. A drive that is undersized, oversized, worn, or damaged can reduce contact with the fastener and increase the risk of rounding or tool damage.
Verify Torque Wrench Compatibility
Allen drives are not universally interchangeable between every hydraulic torque wrench. Confirm the applicable wrench series and drive configuration before selecting an accessory.
Confirm the Required Torque
The Allen drive and the complete hydraulic torque wrench system must be suitable for the torque required by the application. Physical fit alone does not confirm that an accessory is appropriate for a high-torque bolting job.
Applications for Hydraulic Torque Wrench Allen Drives
Allen drives are used in industrial applications involving large socket-head and internal-hex fasteners, including heavy machinery, manufacturing equipment, power generation, structural assemblies, process equipment, and plant maintenance.
Complete Your Hydraulic Bolting System
Pair the correct Allen drive with a compatible Enerpac hydraulic torque wrench, torque wrench pump, hoses, and reaction accessories to create a complete controlled-bolting system.

Enerpac Hydraulic Torque Wrench Allen Drive FAQs
What is a hydraulic torque wrench Allen drive?
An Allen drive is an accessory used to transmit torque from a compatible torque wrench to a fastener with an internal hex recess, such as a socket-head bolt.
How do I choose the correct Allen drive size?
Match the Allen drive to the internal hex size of the fastener and verify that the accessory is compatible with the specific torque wrench model or drive system being used.
Can an Allen drive be used with any Enerpac torque wrench?
No. Compatibility depends on the wrench series, drive configuration, accessory design, and required torque. Always confirm compatibility before use.
Why is proper Allen drive fit important?
Full engagement between the Allen drive and fastener helps distribute torque correctly. Poor fit can damage the fastener, accessory, or surrounding equipment and can create an unsafe bolting condition.
