The APEX 84904 is a 9/16 inch, 6-point impact socket with a 1/4 inch drive, designed for professional tradespeople who demand strength and reliability from their hand tools. Constructed from chrome molybdenum alloy steel, this socket delivers the structural integrity needed to withstand repeated high-torque impact use. A manganese phosphate coating resists corrosion, and laser-etched markings combined with a secondary hard stamping keep the size readable even in dirty shop conditions. Off-corner loading geometry reduces fastener rounding during drive engagement.
This socket is suited for mechanical, electrical, and maintenance trades working on equipment, fixtures, and assemblies that require 1/4 inch drive impact tools. The 9/16 inch SAE sizing covers a broad range of fastener applications found in residential and light commercial service work. It is sold as an individual unit, making it a straightforward replacement or addition to an existing impact socket set.
Designed for use with standard 1/4 inch drive impact wrenches, air ratchets, and hand ratchets in SAE applications requiring a 9/16 inch socket.
This socket is intended for use by qualified tradespeople familiar with impact tool operation. Ensure the drive tool is rated for impact use before attaching the socket. Do not use impact sockets with non-impact ratchets beyond their rated torque, and inspect the socket for cracks or wear before each use. Always wear appropriate eye protection when operating impact tools.
