Single Ended Open Jaw Spanner

It is a commonly used hand tool in the mechanical and automotive industries. It is designed to fit onto nuts and bolts with a unique open-jaw design that allows for easy access in tight spaces. Also known as an Single Open End Spanner or open spanner, it is a type of spanner tool used for tightening or loosening nuts and bolts. 

It features an open jaw at one end, allowing it to easily slip over the nut or bolt head. This type of spanner tool differs from a double-ended spanner, which has jaws at both ends. Single-ended spanners are typically used in tight spaces where a double-ended spanner cannot fit. They are made of high quality materials such as chrome vanadium steel that are durable allowing them to withstand heavy use and resist corrosion.

How does a  single ended open jaw spanner work?

The spanner tool features an open jaw at one end, which allows it to slip over the nut or bolt head. The jaw is designed to grip the flat sides of the nut or bolt head, providing a secure grip and preventing slipping during use. 

1. The spanner is positioned over the nut or bolt head, with the open jaw facing the head

2. The spanner is then rotated in the direction of the desired movement (clockwise to tighten, counterclockwise to loosen)

3. The spanner's jaw grips the flat sides of the nut or bolt head, allowing it to turn with the spanner
