Socket wrench 3/4" 27 mm, Honiton H1627, 6-point drive

Honiton H1627 is a single-piece 6-point 27 mm socket with a 3/4" drive designed for heavy-duty fastening and loosening of nuts and bolts. The socket delivers accurate torque transfer and a secure grip on hexagonal fasteners, and is compatible with 3/4" ratchets, torque wrenches and extensions commonly used in automotive, industrial and workshop environments.

Advantages

The 6-point geometry reduces the risk of rounding fastener corners and concentrates force on the flats for reliable engagement. Constructed as a one-piece socket, it provides consistent internal dimensions for repeatable torque application and improved durability under high loads. The 3/4" drive interface ensures compatibility with a wide range of heavy-duty hand tools, allowing use with torque measurement tools and long-handled breakers when higher leverage is required.

Suitable for

• Automotive repair and maintenance tasks involving larger nuts and bolts
• Industrial assembly and maintenance where higher torque is needed
• Workshop use with 3/4" ratchets, torque wrenches and extensions
• Heavy machinery service and farm equipment maintenance

When it may not be suitable

This socket is intended for use with a 3/4" drive tool and is not compatible with smaller drive sizes without an adapter. It is designed for standard hexagonal fasteners; it may not be appropriate for damaged, rounded, or non-hex fasteners where specialized extractors or different drive profiles are required. For very tight spaces or low-torque precision work, a smaller drive size or specialized low-profile socket would be more suitable.

Key specifications

• Drive size: 3/4"
• Socket size (across flats): 27 mm
• Internal profile: 6-point (hexagon)
• Construction: single-piece socket
• Typical use: high-torque fastening and loosening

How to use

Select a compatible 3/4" drive ratchet, breaker bar or torque wrench and attach the socket securely to the tool. Fit the socket squarely onto the nut or bolt head, ensuring full engagement of the 6-point profile on the flats. Apply steady torque in the correct direction—clockwise to tighten, counterclockwise to loosen—or follow the torque values specified by the equipment manufacturer when using a torque wrench. Use extensions or a breaker bar for additional reach or leverage as required. Inspect the fastener and socket engagement during use to avoid slipping and minimize wear.

What to consider before purchase

• Verify that your existing tools use a 3/4" drive or that you have an appropriate adapter.
• Confirm 27 mm is the correct across-flats size for the fasteners you will work on.
• Consider the torque requirements of your tasks to ensure compatibility with a 3/4" drive socket.
• Assess whether a 6-point profile is preferable to a 12-point or specialty socket for your application.

Usage recommendations

Use the socket with properly rated tools and appropriate torque settings. Store in a dry place to prevent corrosion and inspect for wear or rounding before use. If a fastener shows significant damage, choose a dedicated extractor or repair method rather than applying excessive force that could damage the socket or tool.
