Socket wrench bit Honiton 12-point 1/2" drive 18 mm H1718

The Honiton 12-point 18 mm socket with a 1/2" square drive is a hand tool accessory designed for use with ratchets and torque wrenches. Its 12-point internal profile allows the socket to engage fasteners at multiple rotational positions, making it easier to reach nuts and bolts in confined or awkward spaces. The socket is sized for 18 mm hex fasteners and built for typical automotive, mechanical and maintenance applications where standard metric sockets are required.

Advantages

The 12-point design reduces the need for large swing angles when repositioning the ratchet, improving access in tight areas. Compatibility with a 1/2" square drive ensures it can be used with a wide range of ratchet handles and torque tools. The socket’s metric size provides a precise fit for 18 mm nuts and bolts, helping to minimize rounding of fastener corners and enabling secure torque transfer.

Suitable for

• Automotive repair and maintenance
• Mechanical assembly and disassembly
• General workshop and service tasks with 18 mm metric fasteners
• Use with ratchets and torque wrenches that accept a 1/2" drive

When it may not be suitable

This socket is intended for metric 18 mm hex fasteners and is not appropriate for imperial-size nuts and bolts. It is a single-size tool, so tasks requiring multiple sizes will need a set or additional sockets. If very high torque beyond typical ratchet or standard torque wrench limits is required, consider impact-rated or specialist sockets designed for extreme loads.

Key specifications

• Drive size: 1/2" square drive
• Internal profile: 12-point
• Socket size: 18 mm (metric)
• Intended use: hand-operated ratchets and torque wrenches

How to use

Select a compatible 1/2" drive ratchet or torque wrench and attach the Honiton 18 mm socket by pushing the drive into the socket’s square recess until it clicks or seats. Place the socket over the fastener and apply steady turning force using short ratchet strokes in confined spaces. When using a torque wrench, set the required torque value and tighten the fastener to the specified torque. After use, remove the socket and store it in a toolbox or socket rail to prevent damage and loss.

What to consider before purchase

• Confirm the fastener size is 18 mm (metric) to ensure correct fit.
• Verify your ratchet or torque wrench accepts a 1/2" square drive.
• For heavy-duty or impact applications, consider impact-rated sockets rather than standard hand sockets.

Usage recommendations

Use the socket with appropriately rated hand tools, avoid excessive impact loads, and apply torque within the range of your ratchet or torque wrench. Keep the socket clean and dry and store on a rail or in a case to preserve fit and function.
