คุณลักษณะ

• Use for complex locations where linear work is not possible.
• Can be connected between the socket and handle for angled diagonal work.
• For tightening and loosening bolts and nuts.
• Do not use for power tools such as impact wrenches. Joints consist of convex and concave drives and parts in between. Do not use them roughly because they have low torque transmission efficiency and are vulnerable to impact torque. Both JIS and ISO standards are about half as strong as the ratchet handle. Do not use more than one attachment (Extension Bar, Universal Joint, Socket Adapter).
