The APEX 84900 is a 9/16 inch, 6-point impact socket with a 1/4 inch drive, built for professional trade use in high-torque applications. Constructed from chrome molybdenum alloy steel, this socket delivers the tensile strength needed to withstand repeated impact tool use without cracking or deforming. A manganese phosphate coating provides corrosion resistance for long service life in shop and field environments. Laser-etched markings paired with a secondary hard-stamped size designation keep the socket clearly identified even after heavy use. Off-corner loading geometry reduces the risk of fastener rounding under load.
This socket is suited for mechanical, automotive, and industrial service work where a 1/4 inch drive impact wrench or ratchet is the tool of choice. The 9/16 inch SAE size covers a wide range of fastener applications common in HVAC equipment access panels, plumbing fixture mounting, and general mechanical assembly. Sold individually, it integrates easily into an existing impact socket set or serves as a direct replacement for a worn or lost socket.
Designed for use with 1/4 inch drive impact wrenches, air ratchets, and hand ratchets accepting standard 1/4 inch square drive sockets.
Install and remove with a 1/4 inch drive impact wrench or ratchet. Ensure the socket is fully seated on the fastener before applying torque. Inspect the socket for cracks or deformation before each use and replace if wear is evident. Do not use impact sockets with non-impact hand tools where the torque rating of the drive tool exceeds the socket design limits.
