New Buffalo 84343N Drive Point Deep Impact Metric Socket - 3/8 6 21mm

The New Buffalo 84343N is a professional-grade 3/8-inch drive deep impact socket designed for heavy-duty applications. This 21mm metric socket features a 6-point design that provides superior grip on fastener heads, reducing the risk of rounding and slipping during high-torque operations.

Key Features:

• 3/8-inch drive size for compatibility with standard impact wrenches and ratchets
• 6-point (hex) design for maximum contact with fastener flats, minimizing wear
• Deep socket configuration provides extended reach for recessed fasteners and threaded rods
• 21mm metric sizing for common automotive, machinery, and equipment applications
• Impact-rated construction withstands high-torque power tools and air impacts
• Heat-treated chrome molybdenum steel construction for durability and strength
• Black oxide or phosphate finish for corrosion resistance

This deep impact socket is ideal for automotive repair, mechanical service, and industrial maintenance where standard-length sockets cannot reach. The 6-point design is preferred for impact applications as it distributes force across the fastener's flat sides rather than corners, making it less likely to cause damage to expensive bolts and nuts.
