Specification Brand : uxcell BulletPoint1 : [Size] - 1/2" square drive, 27mm 6-point socket, 200mm (8") total length. BulletPoint2 : [Extra Long Depth] - Provide more space to accommodate longer bolts and a wider range of applications to convenience your work. BulletPoint3 : [CR-V Steel] - Made of heat-treated chrome vanadium steel to improve strength and durability, with polished and electrophoresis finish to prevent rust and corrosion. BulletPoint4 : [Radius Corner Design] - Radius corners prevent fastener wear and increase torque on fasteners by placing force on fastener's flat sides, rather than fastener corners. BulletPoint5 : [Pin Hole] - Individual pinhole base design adds extra security by placing in a locking pin for stability when exerting strong torque motion.

Made of chromium vanadium steel, integral heat treatment, strong force, high torque and good toughness. 2. Electrophoresis surface treatment, not easy to rust and corrosion resistance. 3. Has a 6-point opening, it can fit tightly to the hexagon of the fastener head so that the maximum torque can be applied without slipping. 4. To prevent round-off under stress, it grips the flat sides of the fastener head rather than the corners. 5. The through-hole in the drive end locks onto the tang of wrenches or drivers so it won't fall off or stick on fastener heads. 6. Thicken-wall, electric wrench is available. 7. For disassembly and tightening of hexagon head bolts and nuts, especially suitable for requiring large torque and narrow space. The product has no insulation properties and is not suitable for electrical environments.
