DURALOK™ FASTENING TOOLS are torque devices specifically manufactured to secure and release Duraclamps® and the Bolts.

The super tough plastic clamp that does everything a metal clamp can do and more.

Wedge shape is ideal for a wide variety of square and round tubing.

Hexies are polypropylene floats, hexagonal in shape, with smooth rounded sides. Their unique design creates a "work through" blanket that conserves energy and reduces costs by dramatically decreasing heat and fluid loss, while suppressing odors and vapors. 

Plier type action is ideal for use on specialized shapes and lengths. Molded with the same high strength engineering plastic as the Duraclamp.

Clamps easily adjust to accommodate a wide variety of shapes and sizes. Unique design holds metal firmly throughout the finishing process.

Tests show that Marine Duraclamps can withstand high levels of torque in the most difficult environments. Store them on board in your tool box and they will never corrode. Totally resistant to most chemicals, they'll always work as good as new.
