Socket Bit Proline 1/2" Impact Hex H8 x 60 mm — model 18403

Proline 1/2" Impact Hex H8 x 60 mm (model 18403) is an impact-rated socket bit designed for use with 1/2" drive impact wrenches and rattle guns. The bit features a hex H8 profile with a 60 mm length to reach recessed or partially obstructed hex-head fasteners while maintaining secure engagement under high-torque conditions. It is manufactured for durability in automotive, construction and industrial maintenance environments where impact accessories are required.

Advantages

The impact hex bit is made to resist deformation and cracking when used with impact tools by employing impact-grade steel and heat treatment appropriate for high-torque applications. Its H8 hex profile offers accurate fitment to reduce rounding of fastener corners while the 60 mm length provides extra reach without sacrificing control. The 1/2" drive interface ensures compatibility with a wide range of impact wrenches and accessories commonly used in professional workshops.

Suitable for

• Automotive repair and wheel hub fastening tasks
• Construction and assembly of metal frameworks
• Industrial maintenance and plant equipment servicing
• Any application requiring impact-rated hex drive accessories for H8 fasteners

Key specifications

• Drive size: 1/2" compatible impact drive
• Tip profile: Hex H8
• Overall length: 60 mm
• Intended use: Impact tool applications
• Material treatment: Impact-grade heat-treated steel (impact-rated)

How to use

Attach the Proline 1/2" impact hex bit to the 1/2" drive anvil of the impact wrench until it seats securely. Position the hex tip over the fastener head and apply short bursts of torque with the impact tool, controlling speed and direction to avoid stripping. For removal, set the tool to reverse and use steady, controlled impacts. Inspect the bit and fastener after use for wear or damage and replace the bit if the hex profile becomes rounded or shows cracks.

Usage recommendations

Use appropriate personal protective equipment and verify that the selected torque settings are compatible with the fastener and workpiece. Avoid using the bit in non-impact hand drivers to prevent premature wear, and store in a dry tool tray to limit corrosion and prolong service life.
