What Is a Combination Spanner?
A combination spanner is a dual-purpose tool that integrates the features of both a wrench and a socket wrench, facilitating the tightening and loosening of bolts and nuts. Its design incorporates an open-ended jaw on one end for gripping bolt corners—allowing high torque application—and a ring-shaped socket on the other end for encasing the fastener completely, ensuring a secure, non-slip grip.
Widely used in machinery maintenance, automotive repair, DIY projects, and various fabrication tasks, combination spanners are prized for their functionality, combining two tools in one for convenience and efficiency. Characteristics such as versatility, compact design for easy carrying, and robust construction for longevity make them indispensable in toolkits. However, users should avoid over-torquing and ensure proper engagement with fasteners to prevent damage.
