12 Point Box Strike Wrench 27 mm

The Ampco Safety Tools WS-27 is a non-sparking, non-magnetic striking wrench made from aluminum bronze. It is built for professionals working where flammable vapors, liquids, dust or residue are present. The tool is also suited for use near sensitive magnetic equipment such as MRI and clean room environments. It carries Factory Mutual approval and is beryllium free.

27 mm head size for metric fasteners

The single specification that decides fit is the 27 mm head size, which matches metric fasteners of that dimension. The 12 point box opening engages the fastener securely for striking applications. The head thickness is 13/16 in and the overall length is 7 in, providing the necessary leverage. This wrench is not tether capable.

Striking wrench used with a hammer

Installation means placing the box end over the fastener and striking the handle end with a hammer to apply high torque. The non-sparking aluminum bronze construction prevents ignition hazards during impact. The corrosion resistant material withstands severe environments without degrading. Ensure the 27 mm opening matches the fastener exactly to avoid rounding or slippage.

Questions about this item

What does the 27 mm head size mean when I use this wrench on a fastener?

The 27 mm head fits metric nuts and bolts with a 27 mm across-flats dimension, allowing the 12 point box end to engage the fastener securely for striking applications.

How does the non-sparking, non-magnetic, corrosion-resistant construction affect where I can use this tool?

The aluminum-bronze alloy prevents spark generation in flammable atmospheres, avoids magnetic interference near MRI or clean-room equipment, and resists corrosion in severe environments; it carries Factory Mutual approval for such conditions.

What clearance and length do I need to fit and swing this strike wrench?

The wrench has a 13/16 in head thickness and a 7 in overall length, so you need enough space for the thick box head on the fastener and room to swing the 7 in handle for striking force.
