Trigger Clamps Stanley FATMAX M

The Stanley FATMAX M Trigger Clamp is a compact, reliable clamping tool designed for general workshop and DIY use. Constructed from fiberglass, nylon and resin, it offers a balance of strength and light weight. With a maximum clamping width of 300 mm and a low-profile form factor (161 mm wide, 445 mm deep, 25 mm high), this trigger clamp provides secure holding for gluing, assembly and temporary fastening tasks. The black-and-yellow finish improves visibility on a busy workbench and helps locate the tool quickly.

Advantages

The clamp combines a durable composite construction with an ergonomic trigger mechanism for controlled tightening and release. Its 300 mm clamping capacity covers a wide range of common woodworking and repair tasks while the molded jaws distribute pressure evenly to reduce marring. The lightweight materials reduce user fatigue during repeated use and the visible colour scheme aids fast identification among other tools.

Suitable for

• Holding workpieces during glue-ups and assembly
• Temporary fastening for carpentry and joinery tasks
• Clamping panels, frames and mouldings
• General workshop repairs and DIY projects

How to use

Position the clamp so the jaws align with the surfaces to be held, then squeeze the trigger to advance the movable jaw until the desired clamping pressure is achieved. Release the trigger mechanism to lock the clamp in place. To remove or reposition, press the release lever or appropriate trigger release to free the jaw and withdraw the clamp. Use steady, even pressure when tightening to avoid over-compressing delicate materials.

Usage recommendations

For best results, protect finished surfaces with thin pads or scrap material between the jaws and the workpiece. Inspect the clamp periodically for wear, especially the jaw faces and trigger components, and avoid exposing the tool to prolonged UV or chemical exposure to maintain the integrity of the composite materials.
