Lisle 13660 3/8" Drive Hex Bit Socket 5/16"

The Lisle 13660 is a 3/8-inch drive hex bit socket designed for use with 5/16-inch hex fasteners. This professional-grade socket features a black oxide finish that provides corrosion resistance and reduces glare during use.

Key Features:

• 3/8-inch drive size fits standard ratchets and extensions
• 5/16-inch hex bit for secure engagement with hex fasteners
• Black oxide finish for durability and corrosion resistance
• Precision-machined for accurate fit and long service life
• Ideal for automotive, industrial, and general mechanical applications

This hex bit socket allows you to use your 3/8-inch drive ratchet or breaker bar with internal hex (Allen) fasteners, providing better leverage and control compared to traditional L-shaped hex keys. The socket design is particularly useful in tight spaces where a standard hex key cannot generate sufficient torque.
