A ratcheting combination wrench has a fixed jaw opening and is therefore non-adjustable, placing it under 820411. The ratcheting mechanism controls the direction of torque application but does not change the jaw size. Only wrenches where the jaw opening can be varied — such as a crescent wrench — are adjustable under 820412.

A set consisting solely of socket wrenches, drives, and extensions — all from heading 8204 — remains classified under 8204 (820420). Heading 8206 applies only when the set combines tools from two or more of headings 8202 through 8205. A pure socket set does not cross that threshold and stays within 8204.
