What tool is used to keep the Hi-Lok fastener from spinning as you attach the collar?

A hexagonal wrench is specifically designed to engage with the shaping of the Hi-Lok fastener, providing the necessary grip to prevent it from spinning while the collar is being attached. This tool helps maintain alignment and control during the installation process, ensuring that the fastener is properly secured without losing torque or position.

In the case of Hi-Lok fasteners, which consist of a pin and a collar, affixing the collar while preventing rotation is crucial for the integrity of the assembly. The hexagonal shape of the wrench allows for effective engagement with the hex head of the Hi-Lok pin, facilitating the installation process.

Other tools like a torque wrench are primarily used for measuring and applying a specific amount of torque to fasteners, while pneumatic drivers and socket drivers may not provide the precise control necessary to keep the fastener from spinning during collar attachment. Each of these tools serves its own purpose in fastening applications, but the hexagonal wrench is uniquely suited for this task with Hi-Lok fasteners.
