The APEX 13MM23 is a deep-well metric impact socket designed for high-torque fastening applications in automotive, mechanical, and industrial service work. Built from alloy steel using a proprietary steel and heat treat process, it delivers greater strength, tighter dimensional tolerances, and consistent fit to fasteners for reliable torque transfer. The socket features a 3/8 inch square drive, a 13mm hex opening, and a 6-point drive profile. Overall length is 2 inches, making it suited for reaching recessed fasteners. Licensed trade technicians and professional mechanics are the primary installers of this tool.
The APEX 13MM23 is used in residential and commercial mechanical service environments wherever a deep-well 13mm socket is needed on a 3/8 inch drive impact wrench or ratchet. The deep-well, long-style design accommodates extended fastener shanks, studs, and recessed bolt heads. It is appropriate for automotive repair, equipment maintenance, HVAC mechanical assemblies, and general trade work requiring metric fastener engagement at depth. This socket ships individually and is sold as a single unit.
Designed for use with 3/8 inch drive impact wrenches, ratchets, and extensions requiring a 13mm deep-well metric socket.
Install and remove using a 3/8 inch drive impact wrench or hand ratchet. Verify the socket is fully seated on the drive anvil and fastener before applying torque. Do not use impact sockets on manual torque wrenches unless the tool manufacturer explicitly permits it. Inspect the socket for cracks or deformation before each use and remove from service if damage is found.
