Q 1. What is a KM4 locknut socket used for?

A. The KM4 locknut socket is designed for the safe, accurate installation and removal of KM locknuts — specialised precision nuts used to secure bearings and other critical components on shafts. Specifically, it is used to tighten and loosen lock nuts on tapered journals, adapter sleeves, and withdrawal sleeves.

Q 2. Why can I not use a standard socket or spanner on KM locknuts?

A. KM locknuts feature slots around their circumference, which means a standard socket or spanner cannot engage them correctly. Attempting to use improvised tools risks slippage, rounding, or distortion of the nut and potential damage to the shaft or component it secures.

Q 3. How does the KM4 socket engage with the locknut?

A. The KM4 socket is purpose-built to engage directly with the locknut's slots, providing a positive drive connection that distributes torque evenly. This prevents slippage and distortion, maintaining the integrity of both the locknut and the component it secures.

Q 4. What drive size does the KM4 socket use?

A. The KM4 locknut socket uses a 1/2 inch square drive, allowing it to be used with standard 1/2 inch ratchets and torque wrenches.

Q 5. Can I use a torque wrench with the KM4 socket?

A. Yes. The 1/2 inch square drive on the KM4 socket is fully compatible with ratchets and torque wrenches, enabling accurate torque application during bearing installation and removal.

Q 6. Does the KM4 socket require a lot of clearance around the bearing arrangement?

A. No. The KM4 socket demands less space around the bearing arrangement than a hook spanner, making it practical in confined or restricted access situations.

Q 7. What are the dimensions and weight of the KM4 socket?

A. The KM4 socket measures 35 x 35 x 40 mm (L x W x H) and weighs 0.167 kg.

Q 8. Is an extension tube available for the KM4 socket?

A. Yes. The reach of the KM4 socket can be extended using the 696800-KM4EXT Extension Tube, which is available separately.

Q 9. When will my order be dispatched?

A. In-stock orders placed before 14:30 Monday to Friday are usually dispatched the same day.

Q 10. What warranty does this product come with?

A. Every product comes with a different guarantee and warranty. Warranty details are shown in the product's tech specs or datasheet where available.
