Apex Tools CMS-5422 1/2-Inch Drive 12-Point Spline Socket 11/16-Inch

The Apex Tools CMS-5422 is a professional-grade 1/2-inch drive spline socket designed for 11/16-inch fasteners. This socket features a 12-point spline design that provides superior grip on both hex and 12-point fasteners, making it ideal for high-torque applications where standard sockets may slip or round off fastener corners.

Key Features:

• 1/2-inch drive size for use with standard ratchets and breaker bars
• 11/16-inch socket opening for precise fastener engagement
• 12-point spline design distributes force evenly across fastener surfaces
• Constructed from heat-treated chrome alloy steel for durability
• Ideal for automotive, industrial, and heavy equipment maintenance

Spline sockets are particularly effective on worn or damaged fasteners where conventional hex sockets may fail to grip properly. The CMS-5422 is built to professional standards and is suitable for both hand tools and impact applications.
