【Size】1/2" square drive socket, M11 XZN spline bit, 3.07" (78mm) total length. The lengthened design makes it suitable for more work scenarios. 【Material】Made by drop forged, heat treated heavy duty chrome molybdenum (cr-mo) steel with a corrosion-resistant black phosphate finish, high strength, explosion-proof and durability. 【Great Tool】The impact grade XZN spline bit socket can work under the pressures of impact use and wear resistances, and is suitable to use on all air powered & battery powered impact tools. The XZN triple square bits are a must have for most European vehicles. 【Pin Hole Design】Individual pinhole base design adds extra security by placing in a locking pin for stability when exerting strong torque motion. 【Laser Mark】Size markings have been laser etched for quick and easy identification. High torque socket neet your various purposes. we've got sizes and styles enough to fulfill your need.

Chamfered End
Insert smoothly into the fastener head, reducing wear on the bit and fastener head.

Pin Hole
The through-hole on the drive end allows the use of locking pins & rings to lock the tang of the impact wrench or driver so that it won't fall off or stick on the fastener head. (Note: Do Not Include Pins and Rings ).

Radius Corner Design
Reduces wear and increases torque on fasteners by placing force on fastener walls rather than fastener corners, avoid stress concentrations that can cause cracking.
