Frequently Asked Questions

Does this set include SAE sizes?

No. These nine keys are metric, from 1.5 to 10 mm. Use a correctly sized SAE key for inch-size fasteners rather than substituting a near-fitting metric key.

When should I use the ball end?

Use it when surrounding equipment prevents straight-on access. For loosening tight fasteners or final tightening, use the straight hex end fully seated wherever possible and follow the equipment manufacturer's torque requirements.

Can I use these for arborist and utility equipment maintenance?

Yes, when the equipment uses metric internal-hex fasteners within the included sizes. Confirm the fastener size, clean debris from its recess and isolate equipment according to its service instructions before making adjustments. This set is for hex recesses, not Torx fasteners.

Are these electrically insulated tools?

No electrical insulation rating is specified for this set. Do not rely on the black oxide finish for electrical protection. Follow your crew's electrical safety procedures and use appropriately rated insulated tools where required.
