Spanner Types, know your spanners

Spanners Types

Spanners, also known as wrenches, are essential tools used for gripping, turning, and tightening or loosening fasteners such as nuts, bolts, and screws. There are several types of spanners available, each designed for specific purposes. Here are some common types of spanners and their uses:

Open-End Spanner: This type of spanner has a U-shaped opening at both ends, with each end fitting a specific size of fastener. Open-end spanners are commonly used for tasks where there is ample space around the fastener. They provide quick access and can be used in tight spots.

Combination Spanner: Combination spanners have an open-end on one end and a closed-end (box-end) on the other. The closed-end has a circular opening that provides better grip on the fastener. Combination spanners are versatile and suitable for a wide range of applications. They offer the flexibility of an open-end spanner and the added torque of a closed-end spanner.

Adjustable Spanner (Wrench): Also known as an adjustable crescent wrench or adjustable wrench, this spanner has a movable jaw that can be adjusted to fit different sizes of fasteners. It is particularly useful when working with fasteners of varying sizes. Adjustable spanners are commonly used in plumbing and general maintenance tasks.

Box-End Spanner (Box Wrench): A box-end spanner has a closed-end with a six or twelve-point socket that fully encloses the fastener. This design provides a secure grip on the fastener and allows for higher torque application. Box-end spanners are often used in heavy-duty applications and situations where more force is required.

Ring Spanner (Ring Wrench): A ring spanner has a closed-end with a circular opening that fully encloses the fastener. It offers a secure grip on the fastener from all sides and allows for high torque application. Ring spanners are commonly used in automotive and mechanical applications.

Ratchet Spanner: A ratchet spanner has a ratcheting mechanism incorporated into the closed-end. This allows for continuous rotation without removing the spanner from the fastener. Ratchet spanners are highly convenient when working in tight spaces or when a quick turning action is required.
