What each article number actually is

503.4620’s catalogue says “with reversing lever”, a 15° jaw, a 15° ratchet head and 72 teeth, and it prints 8, 10, 11, 12, 13, 14, 16, 17, 18 and 19 mm. The amazon.co.uk bullets on B00RKI9236 say reversible and do not use the word lever. 503.4250 is the flip set. ToolTeam’s bullets give DIN 3113 / ISO 3318, a 15° jaw, 72 teeth, 8–19 mm, 10 pieces and 1,244 g. They do not say “with reversing lever”. Reviewers of B017RKJHUE say you turn the spanner over, that the photographs show the lever model, and that 503.4620 is the lever article. The ratchet spanner set buying guide puts this check before the star line.

What changes at the fastener

On 503.4250 you seat the ring, pull, then lift the spanner off and turn it over. A hose, a bulkhead or the inner wing can leave no room for that lift. 503.4620’s lever is meant to change direction while the ring stays seated. Neither set should crack a seized nut. That method is on the how to use a ratchet spanner page. If you can turn the spanner over, the flip set does the same spinning job for about £85.51. If you cannot, the lever is the reason to pay about £96.97.

Sizes, price, and the bad Amazon fields

The gap of about £11.46 does not buy 9 mm or 15 mm. 503.4620 prints ten sizes and skips both. 503.4250 does not print its ten sizes. Do not paste 503.4620’s list onto it. 503.4620’s components line says 10 Allen keys. Length says 19 mm, the jaw, not the spanner. Weight says 661 g against a catalogue weight of 1,340 g. Ignore those three fields. Reviews call the case join floppy. 503.4250’s number-of-items field says 1 while the title says 10, and the warranty line says 0 months. ToolTeam’s 1,244 g is a trade-page weight. Choose 503.4620 when the lever matters and you have read the skips. Choose 503.4250 when you have checked there is no lever and the lower price is the point.

When a missing lever is a fault

A missing lever is a fault if the listing you bought described a lever and the tool has none. 503.4620’s catalogue does describe one. 503.4250’s title and trade bullets do not. Reviewers expected a lever because the gallery looked like 503.4620. Under the Consumer Rights Act 2015, goods have to match the description, be of satisfactory quality and be fit for purpose. The short-term right to reject is normally 30 days. A “0 months” line does not cancel that. A photograph of the other article is not the same as a title that says “reversing lever”. Used tools, or a size the title named and then omitted, are a separate complaint. A size the title never listed is not a fault.

Common questions

Which article number has the lever?
503.4620. The KS Tools catalogue says “with reversing lever”. 503.4250’s ToolTeam bullets do not, and amazon.co.uk reviewers say you flip that set. They name 503.4620 as the lever model. The Amazon bullets on 503.4620 itself only say reversible, so use the catalogue line when the thumbnail is ambiguous.
Why do the photographs not settle it?
Reviewers of 503.4250 say the gallery shows a lever the tools do not have. A product image can be the other article number in the same family. Read the catalogue sentence and the article number on the order, then look at the tool that arrives.
What changes in use if you have to flip?
You lift the spanner off the nut and turn it over to change direction. A lever is meant to do that while the ring stays seated. Both still use a 72-tooth, 5° recovery where that tooth count is stated. The flip is only a problem when there is no room to invert the tool.
Is the price gap only the lever?
It is the price gap between about £85.51 and about £96.97 on these captures, and the lever is the clearest specification difference. It does not buy 9 mm or 15 mm. 503.4620 prints those skips. 503.4250 does not print its ten sizes here. Case feel and the bad weight fields are separate issues.
Do both sets skip 9 mm and 15 mm?
503.4620’s title skips both. 503.4250 is described as 10 pieces across 8–19 mm, which cannot include every size, and reviewers mention a missing 15 mm. The other nine sizes on 503.4250 are not printed in this capture, so do not assume they match 503.4620 except for that one reviewer note.
Can you return 503.4250 because it has no lever?
Not on the lever alone, if the title never promised one. You can normally reject goods that are faulty or not as described within 30 days under the Consumer Rights Act 2015. Used tools, or a size the title did name and then omitted, are a different case from a flip set you mistook for 503.4620 in a photograph.
