SK 4421 3/8-Inch Drive 5/8-Inch Extra Long Spark Plug Socket
The SK Hand Tools 5/8-Inch Extra Long Spark Plug Socket features SK's high polish SuperKrome finish, which protects the tools from the harsh working environments found in today's workplace. All included sockets feature SK's SureGrip hex design, which drives the side of the fastener, not the corner, to avoid edge breakage. Breaking can occur on rusted or damaged fasteners when a traditional straight cornered hex tool is used, but the tool's SureGrip design protects against this. The external hex bolster also allows for extra turning power through the use of a wrenches.
