Heavy-duty jobs call for heavy duty tools. The STEELMAN 95845 1/2-Inch Drive x 15-Inch Long Impact Extension Bar is made to give you the reach you need on those tough jobs that demand the most of you and your tools. This durable tool is forged from durable chromoly (CrMo) steel to endure a lifetime of use. This 15-inch extension gives you over a foot of additional reach letting you work on recessed or other hard-to-access fasteners with the power of a pneumatic or electrically powered impact wrench. Made to be compatible with any heavy-duty 1/2-inch drive ratchet, torque wrench, adapter, and socket, this tool is here for the long haul with a rust and corrosion resistant black oxide protective coating. A spring loaded detent ball on the male end of the extension secures attached sockets and a through hole and machined groove around the female end lets you use a retaining ring or cotter pin to hold the extension securely to an impact wrench’s anvil.
