Ultra-thin Hollow Socket for Hydraulic Torque Wrench

The ultra-thin hollow socket for hydraulic torque wrench is purpose-designed for use with the WB and WBT hollow hydraulic torque wrench series, providing the thin-wall, large-bore through-hole profile required to engage directly over the nut face in the cassette-type hollow wrench configuration. Unlike standard sockets, these hollow cassette sockets must fit within the radial space available inside the wrench ring while simultaneously engaging the full nut bearing face, requiring precise dimensional control of both the inner bore profile and the outer cassette seating surface.

The through-bore design accommodates bolt stud protrusion above the nut face while the ultra-thin wall thickness maximizes the nut drive engagement height within the available axial space, ensuring reliable drive engagement even on nuts with minimal height above the joint face. Both metric hex and inch hex internal profiles are available to cover the bolt standards used in major target industries. Material is high-grade alloy steel with heat treatment matched to the cyclic high-torque demands of hydraulic wrench operation.

Socket cassette dimensions are matched to the specific WB and WBT wrench body dimensions for which they are intended, ensuring correct seating in the wrench ring and proper load transfer path from the wrench ring to the nut. Dimensional certification and material traceability are available for quality-critical applications in power generation, oil and gas, and structural engineering where tool component documentation is required. Full cassette sets covering the capacity range of the WB and WBT wrenches are available as inventory kits for maintenance and service operations.
