Apex 84551n 1/2 in Drive Deep Impact Socket 11/16 in

Product Description

The APEX 84551n is a 1/2 inch drive, 6-point deep impact SAE socket sized at 11/16 inch. It is machined from Chrome Molybdenum Alloy Steel (Cr-Mo), a material chosen for its high tensile strength and resistance to the torque loads produced by pneumatic and electric impact drivers. The deep profile allows it to reach fasteners on extended studs, recessed bolts, and long threaded shafts where a standard-depth socket cannot seat fully. An off-corner loading design shifts the drive contact away from the fastener flats, reducing rounding on worn or soft fasteners. This socket is suited for professional mechanics, HVAC installers, and trade technicians who run impact tools daily.

This socket fits into heavy-duty service work across mechanical, HVAC, plumbing, and electrical trades wherever 1/2 inch drive impact tools are standard. The 11/16 inch size covers common fastener applications including conduit connectors, equipment mounting hardware, and structural fasteners. The deep well design is especially useful when driving nuts down long bolt shanks or accessing fasteners inside recessed panels and equipment housings. High-visibility laser-etched size markings and a secondary hard stamping allow fast identification in a cluttered tool tray or impact gun socket rail.

Key Features

• Chrome Molybdenum Alloy Steel (Cr-Mo) construction rated for impact tool torque loads
• 6-point drive geometry for full flat engagement on hex fasteners
• Off-corner loading design reduces fastener rounding during high-torque applications
• Deep profile reaches extended studs, recessed bolts, and long threaded fasteners
• Manganese phosphate coating provides corrosion resistance in wet or outdoor environments
• Dual identification: high-visibility laser-etched markings plus secondary hard stamping

Compatibility

Designed for use with standard 1/2 inch drive impact wrenches, ratchets, and torque wrenches across professional and industrial tool platforms.

Installation Notes

Seat the socket fully onto the impact driver anvil before applying torque to prevent slippage or anvil wear. Inspect the socket and retaining ring for cracks or deformation before each use, as impact sockets are subject to fatigue over time. Always use impact-rated sockets with pneumatic or electric impact tools — chrome-finish hand-tool sockets are not rated for impact loads. Keep the socket clean and lightly oiled at the drive square to maintain fit and reduce wear.
