[Included] - 1/2' drive 17mm 6-point socket, 3' total length; 1/4' hex shank, 2.87' length socket adapter. [Extra Depth] - Provide more space to accommodate longer bolts and a wider range of applications to convenience your work. [Secure/Firm] - Spring-loaded ball to retain sockets and prevent them from dropping. [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. [Hex Shank Socket Adapter] - Attach to any powered / cordless drill chuck or impact driver to turn it into a high-speed nut driver.
Durable Construction Made with chromium-vanadium steel forging, high strength and good wear resistance, durable to use. For disassembly and tightening of hexagon head bolts and nuts, especially suitable for requiring large torque and narrow space. Hex Shank Socket Adapter Provide extra length to access hard-to-touch spaces. Specifically machined to be securely installed in a handheld screwdriver, drill driver or impact wrench. 6-Point Socket It can fit tightly to the hexagon of the fastener head so that the maximum torque can be applied without slipping. Specification: Socket - Square Drive: 1/2-inch Total Length: 78mm / 3-inch Socket Adapter - Hex Shank: 1/4-inch Square Drive: 1/2-inch Total Length: 73mm / 2.87-inch Product Details 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 ). Spring Loaded Ball Detent & Chamfered End Locks securely onto sockets and prevents them from being dropped for undisturbed work and improving accuracy and efficiency when working. 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.
