Where this product is used

Ko-Ken inhex (internal hex) sockets drive Allen and hex head fasteners through a socket drive, providing better torque transfer and access in confined spaces compared to standard L-keys.

• Allen and hex head fastener driving in automotive, engineering, and machinery assembly applications
• Ratchet-driven hex fastener tightening where standard L-key torque is insufficient
• Access to recessed or deep hex fasteners with the benefit of socket drive extension bars

Key specifications

Selecting the right option

Select by drive size and hex size in mm (metric) or AF (imperial) to match the fastener and the ratchet or torque wrench being used. Inhex sockets suit situations where torque wrench control is required on Allen fasteners, or where L-key access is difficult. Confirm the key size engages correctly — an incorrect size will damage both the fastener and the socket.
