Heavy-duty jobs call for heavy duty tools. The STEELMAN PRO 79369 1/4-Inch Drive x 6-Inch Long Friction Ball Impact Extension Bar is made to give you the extra reach you need on those tough jobs that demand the most of you and your tools. This durable tool is forged from resilient chromoly (CrMo) steel to endure a lifetime of long, high stress use. The tool’s 6-inch length gives you that little bit of extra reach you need when working on recessed or hard-to-access fasteners with a pneumatic or electrically powered impact wrench. Made to be compatible with any heavy-duty 1/4-inch drive ratchet, torque wrench, adapter, and socket, this tool is here for the long haul with a rust and corrosion resistant black phosphate protective coating. A spring loaded friction ball on the male end of the extension secures attached sockets and a ball detent recess on the female end holds the extension securely to a ratchet or other drive tool. Designed to meet or exceed ASME tool standards this extension is covered by a limited lifetime guarantee.
