Performance Tool M899 Drive Impact Socket - 3/8 6-Point 13/16

The Performance Tool M899 is a heavy-duty 3/8" drive impact socket designed for use with impact wrenches and air tools. This professional-grade socket features a 13/16" (6-point) hex opening, providing superior grip on fasteners while minimizing the risk of rounding corners during high-torque applications.

Key Features:

• 3/8" drive size for compatibility with standard impact drivers
• 13/16" socket opening with 6-point design for maximum contact and reduced slippage
• Impact-rated construction from hardened chrome molybdenum steel for durability
• Black oxide finish resists corrosion and clearly identifies impact-rated sockets
• Thicker walls than standard sockets to withstand impact tool forces

This impact socket is ideal for automotive repair, equipment maintenance, and general mechanical applications where pneumatic or electric impact tools are used. The 6-point design is preferred for heavy-duty work as it grips the flat sides of fasteners rather than the corners, reducing wear on both the socket and fastener.
