Socket Bit 1/2" GEKO T00143-11 11 mm 12-point (hexalobular) insert, hardened, pack sizes 10/100

GEKO Socket Bit T00143-11 is a 1/2" drive, 11 mm, 12-point (double hex / hexalobular) insert engineered for use with ratchets and torque tools. Manufactured from hardened steel, this socket bit is intended for repeated fastening and loosening of 12-point fasteners commonly found in automotive, industrial maintenance and assembly applications. Available in pack sizes of 10 or 100 pieces, the design focuses on durability and consistent engagement with 12-point heads.

Advantages

The hardened steel construction improves resistance to wear and deformation during high-torque applications, while the 12-point profile allows multiple engagement positions for easier alignment with fasteners. The 1/2" drive interface ensures compatibility with standard ratchets and torque wrenches used in professional repair and assembly environments. Pack options of 10 or 100 pieces provide flexibility for individual technicians or larger workshops and production lines.

Suitable for

• Automotive repair and service tasks involving 12-point fasteners
• Industrial maintenance and machinery assembly
• Workshop and production environments requiring bulk socket bits
• Application with 1/2" drive ratchets and torque tools

Key specifications

• Drive size: 1/2" compatible interface for ratchets and torque wrenches
• Insert size: 11 mm nominal across flats for 12-point fasteners
• Profile: 12-point (double hex / hexalobular) for multiple engagement angles
• Material: hardened steel for improved wear resistance
• Pack sizes: available in packs of 10 or 100 pieces

How to use

Select the 11 mm 12-point socket bit and attach it securely to a 1/2" drive ratchet or torque wrench. Position the bit over the corresponding 12-point fastener and apply torque in a controlled manner, keeping the tool aligned with the fastener axis to avoid rounding. For high-torque or precision applications, use an appropriate torque setting and verify engagement before applying full force. After use, inspect bits for wear and replace any units showing deformation or rounding at the contact surfaces.

Usage recommendations

Use with properly sized 1/2" drive tooling and matched 12-point fasteners. For long service life, avoid excessive side-loads and remove bits showing visible wear or cracking. Keep bits clean and lightly lubricated if used in corrosive environments to maintain reliable engagement.
