SATA GL25201 1/2" Drive Long Hex Bit Socket 4mm

The extended length lets you reach fasteners that are deep, obstructed, or hard to access, improving reach and reducing tool repositioning in tight spaces.

1/2" drive compatibility, 4mm hex bit, extended long-socket design, chrome-plated corrosion-resistant finish, laser-etched size markings, and heat-treated durability for heavy use.

The 4mm hex bit is machined to tight tolerances for a precise engagement, minimizing cam-out and providing reliable torque transfer.

Automotive repairs, machinery maintenance, bicycle and motorcycle servicing, appliance repair, and any task requiring reach into recessed or obstructed fasteners.

Attach the socket to a 1/2" drive ratchet or torque wrench, align the 4mm hex bit with the fastener, apply steady torque, and remove once the fastener is secured.

Yes, it’s designed for impact-ready use, but always wear eye protection and follow tool manufacturer guidelines to avoid over-torquing or damaging fasteners.

The long socket provides greater reach to access recessed fasteners, while the integrated 4mm bit offers convenience and secure engagement that may reduce slipping in tight spaces.
