Impact Extension Bar 200 mm 1" with Through Hole — Rockforce

Rockforce Impact Extension Bar 200 mm 1" with Through Hole provides a durable, extended reach solution for impact wrench and pneumatic tool applications. The 200 mm length increases access to recessed or hard-to-reach fasteners while the 1" drive fits compatible impact sockets and accessories. A through hole allows secure use of a retaining pin or spring retainer to prevent socket separation during high-torque operations.

Advantages

The extension bar is manufactured for compatibility with impact tools and is heat-treated to withstand repeated high-torque loads typical of automotive, industrial maintenance and construction work. Its through-hole design ensures reliable socket retention under vibration and sudden torque changes. The simple cylindrical profile and standard 1" drive make it easy to pair with a wide range of heavy-duty sockets and adapters.

Suitable for

• Accessing recessed bolts and nuts in automotive repair
• Industrial maintenance where extended reach is needed
• Construction and assembly tasks with heavy fasteners
• Pneumatic and electric impact wrench applications

Key specifications

• Length: 200 mm
• Drive size: 1 inch
• Design: solid extension bar with through hole for pin or retainer
• Intended use: impact-rated for use with impact wrenches and pneumatic tools
• Material/treatment: heat-treated steel suitable for high-torque applications

How to use

Select the appropriate 1" impact socket and slide it onto the extension bar. Insert the extension bar into the impact wrench or adapter, ensuring the connection is secure. If necessary, insert a retaining pin or spring retainer through the through hole to lock the socket in place before applying torque. Operate the impact tool according to the manufacturer's instructions and recommended torque ranges for the fasteners you are working on.

Usage recommendations

Use only impact-rated sockets and accessories with this extension bar. Inspect the extension bar and retaining hole for wear or deformation before each use. Avoid using cheater bars or applying non-standard loading that could exceed the product's intended impact-rated capacity.
