Socket bit for ratchet 20.0 mm long, CrV, 1/2" drive GEKO

Long 20.0 mm socket bit for 1/2" ratchet drive by GEKO, manufactured from chrome-vanadium (CrV) steel for consistent hardness and wear resistance. This socket bit provides extended reach compared with standard sockets, allowing access to recessed or hard-to-reach nuts and bolts while remaining compatible with standard 1/2" drive ratchets, extensions and torque tools. The compact hex profile ensures secure seating on fasteners and reduces cam-out during tightening and loosening operations.

Advantages

The GEKO 20.0 mm long socket bit combines CrV construction with a 1/2" drive interface to deliver reliable strength and durability for repeated workshop use. Its extended length improves accessibility in tight engine bays, machinery housings and assembly fixtures. Precision-machined edges and a uniform finish help ensure a firm fit on fasteners, which minimizes rounding and wear on both the tool and the component.

Suitable for

• Automotive repair and maintenance where recessed fasteners are present
• General workshop assembly and disassembly tasks
• Industrial maintenance on machinery and equipment with limited access
• Use with 1/2" drive ratchets, torque wrenches and extension bars

Key specifications

• Drive size: 1/2" compatible
• Socket diameter: 20.0 mm
• Overall length: long (20.0 mm socket depth on extended bit body)
• Material: chrome-vanadium (CrV) steel
• Finish: machined surface for secure fit and corrosion resistance

How to use

Attach the socket bit to a compatible 1/2" drive ratchet, extension or torque tool by inserting the square drive into the tool's receptacle until it locks. Position the socket over the nut or bolt head, ensuring full seating on the fastener before applying torque. Turn the ratchet or torque tool in the required direction to loosen or tighten; when using torque-sensitive operations, follow the recommended torque settings for the fastener and tool. Remove the bit by depressing the drive ball or release mechanism on the ratchet or extension and pull the bit free.

Usage recommendations

Use the socket bit with properly rated 1/2" drive tools and avoid applying impacts or excessive torque beyond the bit's intended capacity. Keep the bit clean and lightly oiled after use to reduce corrosion. For critical torque applications, verify calibration of the torque wrench and choose the correct socket size and length to prevent fastener damage.
