Socket bit 1/4" 12 mm long hex GEKO T00141-12, set sizes 10/100 optional

Long hex socket bit for 1/4" drive, GEKO model T00141-12 with a 12 mm hex size. This tool is designed for fastening and loosening hex-head fasteners in confined or recessed areas where a standard-length bit may not reach. It is compatible with 1/4" manual ratchets, bit holders and adapters, providing extended reach for tasks in automotive maintenance, machinery repair, assembly and general servicing.

Advantages

The long 12 mm hex design gives improved access to recessed bolts while maintaining a secure fit on hex fasteners. Constructed from hardened steel with a precisely machined hex profile, the bit resists rounding of fastener corners and provides reliable torque transfer. Its 1/4" drive shank ensures compatibility with a wide range of drivers and adapters, making it a versatile addition to tool kits that require extended reach without sacrificing control.

Suitable for

• Automotive repairs where bolts are recessed or obstructed
• Machine maintenance and equipment servicing in tight spaces
• Assembly tasks requiring precise access to hex fasteners
• General household and workshop repairs with 1/4" drivers

Key specifications

• Drive size: 1/4" compatible shank for manual ratchets and bit holders
• Hex tip size: 12 mm
• Length: long/extended profile for access to recessed fasteners
• Material: hardened steel with machined hex profile for durability
• Finish: corrosion-resistant surface treatment for longer service life

How to use

Insert the 1/4" shank of the socket bit into a compatible ratchet, bit holder or adapter and ensure it is securely seated. Place the hex tip onto the fastener head and apply steady torque, keeping the bit aligned with the fastener axis to avoid cam-out or rounding. For tight or recessed fasteners, use the extended length to reach the head while maintaining a stable grip on the driver. Remove the bit from the driver after use and store it in a designated slot in your tool kit to prevent loss.

Usage recommendations

Use appropriate hand tools and wear eye protection when working on machinery. Avoid applying impact or excessive bending loads to the bit; for heavy torque applications, select a socket or tool rated for those forces. Keep the bit clean and lightly lubricated if exposed to corrosive environments.
