Frequently Asked Questions

Are these sockets designed for impact tools?

Yes. They are manufactured from heat-treated Chrome Molybdenum steel and are specifically designed for use with pneumatic impact guns and cordless impact wrenches.

What is the advantage of a 6-point socket?

A 6-point profile provides greater contact with the flats of the fastener, helping to reduce slipping and minimise rounding under high torque.

What sizes are included?

The set contains nineteen metric sockets from 6mm to 24mm, including every size from 6mm through to 24mm.

What are the pin-and-ring holes for?

The dual retention holes allow sockets to be secured to compatible impact tools using a retaining pin and O-ring, helping prevent accidental socket detachment during heavy-duty use.

The ball-retaining groove provides a secure connection between the socket and 3/8" drive ratchets, extensions and impact tools.

Can these sockets be used with a standard 3/8" ratchet?

Yes. They are compatible with all standard 3/8" square drive ratchets, extensions and breaker bars, as well as impact tools.
