Frequently Asked Questions

1. Are these hex bit sockets suitable for impact wrenches and impact drivers?
Yes. These hex bit sockets are manufactured from premium heat-treated Chrome Molybdenum (Cr-Mo) steel and are designed for use with pneumatic impact wrenches, cordless impact wrenches and impact drivers. However, when working with smaller hex fasteners, it is recommended to use lower power settings or controlled torque to help prevent damage to the fastener or hex socket. This ensures maximum performance while reducing the risk of stripping or rounding the fastener.

2. What sizes are included in the set?
The set includes eleven 60mm long hex (Allen) bit sockets in sizes 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 10mm, 12mm, 14mm, 17mm and 19mm.

3. What are hex (Allen) impact bit sockets commonly used for?
Hex impact bit sockets are commonly used on automotive brake components, suspension systems, engine assemblies, motorcycles, machinery and industrial equipment where internal hex fasteners require higher torque for removal or installation.

4. Can individual sockets be purchased separately?
Yes. Individual replacement sizes are available, allowing you to replace a lost or damaged socket without buying a complete new set.

5. How is the set stored?
The set is supplied in a durable EVA foam tool control tray with a dedicated location for every socket. The tray fits neatly into most tool chests, roll cabs and top boxes, helping to keep your tools organised and easy to locate.
