Use this hook spanner from SKF to loosen or tighten a bearing lock nut without damaging it. The device's jaw features a small hook at its end that keys into the nut and ensures you achieve a secure hold. You can adjust the jaw to accept nuts sized between 20 and 22mm to suit your requirements. Thanks to a durable plastic handle that's resistant to dirt and oil, you can maintain a secure grip while you work. A hole in the handle lets you hang the spanner up safely when it's not in use.

• Plastic handle covering minimises direct contact and reduces the risk of corrosion
• Laser-engraved size specification for quick identification
• Can be used on bearings mounted on a shaft or sleeve for versatility

• Manufacturing assembly lines
• Mining and quarrying industry
• Automotive workshops

You can use a vernier calliper to measure the diameter of the lock nut you want to remove. This lets you adjust the jaw size of the spanner accordingly and ensure you get a good grip.
