Screwdriver bit Proline ZR18645, 1 pc, 1/2" drive, 55 mm length

Proline ZR18645 is a single 55 mm screwdriver bit designed for tools with a 1/2" drive. Manufactured to fit standard 1/2" sockets and bit holders, this bit provides a medium-length option for general fastening and maintenance tasks in workshops, construction sites and repair environments. The compact length and 1/2" interface make it compatible with torque tools and ratchets that accept exchangeable bits.

Advantages

The bit offers a standard 1/2" drive interface that ensures compatibility with a wide range of sockets and bit holders. Its 55 mm length balances reach and control for tasks where a full-length bit would be unwieldy or a very short bit would not reach fasteners. Supplied as a single piece, it is convenient for replacing worn bits or building a tailored bit set for professional or DIY use.

Suitable for

• Workshop assembly and disassembly tasks
• Construction and on-site fastening jobs
• General maintenance and repair work
• Use with 1/2" drive ratchets, torque wrenches and bit holders

Key specifications

• Drive type: 1/2" drive

How to use

Insert the Proline 1/2" bit into a compatible 1/2" drive socket, bit holder or ratchet until it locks securely. Select the appropriate tool and fastening direction, apply steady pressure and turn at controlled speed to engage or remove fasteners. Inspect the bit tip before use and replace it if worn to avoid damage to fasteners. After use, store the bit in a holder or toolbox to protect the tip and maintain readiness for the next task.

Usage recommendations

Use this 55 mm bit where a medium reach and a 1/2" drive interface are required; avoid applying excessive torque beyond the tool or fastener rating and replace the bit when signs of wear or deformation appear to maintain safe and accurate fastening.
