Ampco - 16mm x 18mm 12 Point Box Wrench - Double End, Aluminum Bronze, Plain Finish

Box wrenches are used for tightening and loosening bolts or nuts in areas where movement is limited. The end(s) of the box wrench are designed with an enclosure that can be placed over the fastener for gripping and rotating.

Non-ratcheting wrenches must disengage and re-engage from the fastener to loosen or tighten.

Non-sparking wrenches are used in environments where flammable or combustible elements are present.

Double end wrenches are designed with two working ends which may be the same or different sizes.

Plain, uncoated tools do not have a finish or coating.

Aluminum bronze offers non-sparking, non-magnetic and corrosion-resistant properties and is ideal for use where flammable or combustible elements are present.
