Self-Clamping Soldering Jig

Take the stress (and hand-strain) out of soldering power leads and connectors with this Self-Clamping Soldering Jig. Designed for RC builders and makers, this injection-moulded jig features two independent spring-loaded clampa with a maximum opening of around 13 mm – perfect for gripping XT60s, Deans-style plugs, bullet connectors, and thick silicone wire without needing a third hand.

The jig includes two vertical jaws for pairing wires or anchoring leads before soldering, helping to prevent slips, cold joints, or singed fingertips.

Made from heat-resistant, non-conductive plastic, it’s safe to use around sensitive electronics and won’t short out components like metal or carbon-based alternatives might.

Whether you’re wiring a new drone, repairing an ESC power lead, or assembling battery packs in the field, this compact tool keeps everything steady for cleaner, faster joints.

Why we like it:

• Reliable one-hand clamp action for stress-free soldering
• Spring clamp opens to ~13 mm to handle common RC connectors
• Holds plugs and wires securely for neat, controlled joints
• Heat-resistant, injection-moulded body won’t scratch or short components
• Lightweight and portable – great for the bench or your field kit

A simple but invaluable tool for anyone who solders regularly and wants cleaner, safer results – especially when working with chunky battery leads.

Two Colour Options: Black & Blue.
