Lock Nut Spanner TMHN 7

Specifications

How to choose Spanners

Points to check when selecting, with the values for this product (TMHN 7).

1. 1. Match the locknut number

   This product: Compatible Nut Nominal Number 5～11

   Hook spanners are supplied for each corresponding locknut number, such as HN 4 or HN 5, so the number determines compatibility. If the claw and nut groove dimensions do not match, the tool slips and can damage the nut or groove, so confirm that the locknut number to be used falls within the compatible range.

2. 2. Check the outer diameter range

   The outer diameter range of locknuts that a spanner can engage is set for each product, and listed products cover 16 to 210 mm. Adjustable types cover multiple outer diameters with one tool, but the range is limited, so check that all the nut outer diameters you have fall within it.

3. 3. Select the spanner type for the task

   For reliably gripping a specific size, the hook type is suitable; where sizes are mixed on site, the adjustable type is suitable; and where manual force is insufficient for large nuts, the impact type used with a hammer is suitable. If the nut has holes in its face, the pin type is required. Decide the type based on the nut shape and the work content.

4. 4. Check large units against outer diameter d and dimensions

   For large locknuts, the catalogue may indicate compatibility by the applicable outer diameter d, and listed products cover 148 to 746 mm. Surrounding space and the swing radius are also relevant, so check together with overall length L whether the tool fits in the work area.

5. 5. Control angle for tapered seat mounting

   When mounting self-aligning ball bearings and similar units on tapered shafts or adapter sleeves, controlling the push-in amount by tightening angle prevents over- or under-tightening. Sets with a protractor are intended for this application, and for sets supplied with a carrying case, also confirm the storage dimensions.

6. 6. Check handle material and identification

   In humid sites, corrosion-resistant materials such as resin handles are easier to handle. When holding many sizes, markings showing the model number or compatible range help prevent mix-ups. Check the body material and markings, including storage methods.
