Extended Reach for Somerville Torque Systems

In tight spaces where wrenches can’t reach, Action Extension Bars Somerville give trades the control & torque transfer needed to keep precision within reach. Built for mechanics, fitters & industrial technicians, these bars extend your impact setup while maintaining balance & strength under heavy load.

Forged from impact-rated alloy steel, the bars are hardened to resist twisting under pressure. Quick-change pin & steel-ball retention systems keep sockets locked during vibration, while precision-machined shafts deliver smooth torque transfer from wrench to fastener. Whether accessing deep fittings or offset assemblies, these extensions provide total control across all connections.

All models are torque-tested individually to meet or exceed ratings for pneumatic & cordless impact tools, ensuring consistent output through demanding cycles. Ideal for automotive repair, fabrication & heavy assembly, they’re built to withstand real workshop punishment while maintaining alignment & drive integrity.

Use with Impact Wrenches for high-torque performance, pair seamlessly with Impact Sockets & Sets, connect via Air Hoses & Reels for steady pneumatic flow & secure your setup using Quick Couplers & Connectors. Keep tools organized on Workbenches & stored inside Tool Boxes & Bags for efficient operation across Somerville sites.

Frequently Asked Questions

Yes — every bar is impact-rated & tested to exceed torque loads typical of pneumatic & cordless wrenches, ensuring safe, consistent torque transfer.

Quick-change bars use steel-ball retention for faster socket swaps, while pin-lock versions provide extra security for heavy-duty or overhead work.

No — torque-limiting bars complement torque wrenches. They control maximum torque delivery but aren’t for calibrated measurements. Always verify with a proper torque wrench when accuracy is critical.

Clean shafts after use, apply a light protective film with Lubrication & Cleaning Gear & store them inside Tool Boxes & Bags or secured racks on Workbenches.
