Apex 80666 Triple Square Bit Socket 1/2 in Drive 12 Mm

Product Description

The APEX 80666 is a 1/2 inch drive Triple Square bit socket designed for fastening and removal of XZN-profile fasteners commonly found on European vehicles. The base socket is constructed from heat-treated alloy steel for durability and extended tool life. The bit itself is manufactured from S2 steel, a high-impact tool steel that resists rounding and breakage under heavy torque loads. At 4.68 inches in length and 12 MM in size, this socket provides adequate reach for recessed fastener locations typical in European automotive applications. It is sized for use in professional repair bays, fleet shops, and specialty automotive service environments.

Triple Square, also called XZN, fasteners appear frequently on German and other European vehicle platforms, particularly on drivetrain, suspension, and brake components. This bit socket is intended for use by automotive technicians and professional mechanics working on vehicles that require XZN tooling. The 1/2 inch drive interface is compatible with standard 1/2 inch drive ratchets, breaker bars, and torque wrenches, making it straightforward to integrate into an existing tool setup.

Installation Notes

This bit socket is intended for use by qualified automotive technicians. Before loosening or torquing fasteners, ensure the vehicle is properly supported and relevant systems are depressurized or powered down as required. Seat the socket fully onto the fastener before applying torque to avoid fastener rounding or bit damage. Inspect the bit tip for wear before use on critical drivetrain or brake fasteners.
