The APEX 84133 is a 1/4 inch drive, 6-point impact socket with a manganese phosphate coating, built for professional use in high-torque applications. Constructed from chrome molybdenum alloy steel, this socket delivers the tensile strength required to withstand repeated impact tool use without cracking or deforming. Off-corner loading geometry reduces contact stress on fastener flats, which limits rounding on worn or corroded hardware. Laser-etched size markings stay legible in dirty shop conditions, and a secondary hard-stamped size adds a backup ID method when coatings wear.
This socket is suited for automotive, fleet, and general mechanical service work where a 1/4 inch drive impact tool is the appropriate drive size. It is sold as a single unit, making it a direct replacement or add-on for existing socket sets. The manganese phosphate finish makes it a practical choice for technicians working in environments where corrosion is a concern, such as undercar service, marine mechanical work, or outdoor equipment repair.
Designed as an OEM-style replacement or standalone addition compatible with standard 1/4 inch drive impact tools and socket sets.
Installation of this socket requires only a compatible 1/4 inch drive impact wrench or ratchet. Before use, confirm the drive and socket are fully engaged and the retaining mechanism is secure. Do not use impact sockets with standard hand-ratchet extensions rated only for hand-torque applications. Inspect the socket for cracks or deformation before each use and remove from service if damage is found.
