A combination spanner set is a group of wrenches with two different types of ends: an open-end wrench at one end and a ring or box-end wrench at the other end. These wrenches are designed to tighten or loosen nuts and bolts of various sizes.
Key features:
- Open-End Wrench: One end of the combination spanner is an open-end wrench with a U-shaped or C-shaped design. This end is designed to fit onto the flat sides of a nut or bolt.
- Ring or Box-End Wrench: The other end features a ring or box-end wrench, which has a closed loop or box-shaped design. This end provides a secure grip on the nut or bolt by fully enclosing it.
- Variety of Sizes: Combination spanner sets include wrenches in different sizes to accommodate various nut and bolt sizes. These sizes are typically measured in both metric and imperial units.
- Durable Material: Spanners are often made from durable materials such as alloy steel or chrome vanadium, which can withstand high levels of torque without breaking.
- Both Metric and Imperial Units: Sets may include a combination of metric (millimeter) and imperial (inch) wrenches to cover a wide range of fastener sizes.
- Laser-Etched Size Markings: Many combination spanners have the wrench size laser-etched or stamped onto the tools, making it easy to identify the right size quickly.
- Compact and Portable: Combination spanner sets are compact and portable, suitable for various repair or maintenance tasks, including on-site work.
- Organized Storage: These sets often come with a storage case or holder, which keeps the spanners organized and easily accessible.
- Versatile Use: Combination spanners can be used in various applications, including automotive repair, plumbing, construction, and machinery maintenance.
- Precision and Control: The wrenches provide precision and control when turning nuts and bolts, making them an essential part of many toolkits.
- Ratcheting Feature: Some combination spanner sets may feature a ratcheting box-end design, allowing for faster turning of fasteners without removing the wrench.
- Angle Offset: Some ring ends of combination spanners have an angle offset, which can be useful for accessing tight spaces or providing extra leverage.
- Size: 6-32mm
