Sign up for Wiha 351 SW 5.5mm Short Arm Allen Key / Hex Key – Professional Quality L-Wrench
Need a specific 5.5mm hex key?
This Wiha short arm Allen key is a professional-grade tool you can count on.
Wiha is a respected German tool brand known for quality and precision.
The 351 SW designation means it's a short arm, L-shaped wrench, which gives you good torque in tight spaces where a longer arm wouldn't fit.
The 5.5mm size is a less common metric size, but it's crucial for certain furniture assembly, machinery, bicycles, or automotive applications.
Made from hardened steel, it's tough and resistant to rounding out.
The finish is clean, and the edges are sharp for a secure fit in socket head screws.
It's a single, standalone key, not part of a set, so it's perfect if you just need to replace a lost one or have a specific job that requires this exact size.
Keep it in your tool roll, bike repair kit, or workshop drawer for whenever that particular bolt shows up.
Simple, reliable, and built to last.
