Apex 84394 Impact Bit Socket 3/8 in Drive Hex 10 Mm

Product Description

The APEX 84394 is a standard-length impact bit socket designed for 3/8 inch drive tools with a hex bit configuration in 10 MM. Built from chrome molybdenum alloy steel, it delivers the torsional strength needed to handle high-torque impact driver output without cracking or deforming. A manganese phosphate coating provides corrosion resistance for jobsite and shop environments. Laser-etched markings combined with a secondary hard stamping keep the size readable even after heavy use. Off-corner loading geometry reduces rounding on fastener heads, extending the working life of both the socket and the fastener.

This socket is suited for professional mechanics, maintenance technicians, and tradespeople who run 3/8 inch drive impact wrenches or impact drivers. It covers common assembly, disassembly, and service tasks on automotive, HVAC, and mechanical equipment where a 10 MM hex drive bit is required. The standard length profile fits into tight clearances while still providing adequate depth for most fastener applications. Sold individually, it works as a direct addition to an existing 3/8 inch drive impact socket set.

Key Features

• Chrome molybdenum alloy steel construction for high-torque impact resistance
• Manganese phosphate coating resists corrosion in wet and chemical-exposure environments
• Laser-etched markings with secondary hard stamping for permanent, readable size identification
• Off-corner loading reduces fastener rounding during high-torque application
• Standard length profile compatible with 3/8 inch drive impact tools
• 10 MM hex bit configuration for common metric fastener sizes

Compatibility

Designed as an OEM-style replacement and add-on socket for 3/8 inch drive impact wrenches and impact drivers using standard-length hex bit sockets.

Installation Notes

Installation is performed by mechanics and service technicians using 3/8 inch drive impact wrenches or manual ratchets. Ensure the socket is fully seated on the drive anvil before applying torque. Inspect the socket for cracks or wear before each use, and do not use impact-rated sockets on non-impact hand tools beyond their rated torque capacity.
