55 mm Non-Sparking Strike Wrench

This 12-point box strike wrench is built for hazardous environments where flammable vapours, combustible dust or sensitive magnetic equipment are present. The aluminium-bronze construction is non-sparking, non-magnetic and corrosion resistant, and it carries Factory Mutual approval. It is made in the USA without beryllium.

Suited for Maintenance in Explosive or MRI Areas

Mechanics and technicians working in refineries, chemical plants or clean rooms will benefit from the spark-free and non-magnetic properties. Buyers who need a ratcheting mechanism, a tether attachment point or an adjustable jaw should look at other tool types because this wrench offers none of those features.

Verify Fastener Size and Clearance Before Purchase

Confirm that the fastener you intend to turn measures exactly 55 mm across the flats, as the 12-point box head fits only that size. Ensure the 10-inch overall length and 1 1/8-inch head thickness can reach the bolt within your workspace, and check that a striking wrench is the correct tool for your application.
