Adjustable spanner vs combination spanner

Updated: 22 October 2026

An adjustable looks as if it replaces a rack. One handle, a worm, and every nut from a furniture bolt to a bath fitting. It does that until the fastener is tight, or until the same size comes up again and the jaw has to be reset. This comparison is adjustable spanner vs combination spanner: what each end grips, when one tool is enough, and when the set earns the space. The shelf these examples come from is the [spanner comparison](/hub/hand-tools/spanner). Peter F. read the captured listings and UK guides on the two types. There is no counted slip rate.

What each tool grips

A combination spanner has an open end and a ring of one size. The open end reaches past a pipe. The ring stays on a tight bolt. Hilka's 11-piece set is that pattern, metric, at £8.68. The checks before the type are on the spanner buying guide. An adjustable is one fixed jaw and one on a screw. RS notes many sizes, a bulkier head, and a jaw that can wander. Hagerty treats it as a fallback. CAR magazine's primer gives an open end about 60 degrees for a new bite and a 12-point ring about 30. Do not stamp 12-point on Hilka. The file does not say. The Ginddy, £5.99, is one 13 mm ratchet with no reviews.

When the adjustable is the right only tool

Buy an adjustable when the size is unknown or larger than a small metric run. A 200 mm title is the handle. Stanley's 0-90-948 is £7.99, 4.6 from 5,584, bullet 24/200 mm, jaw field 8 inches. Leave that inch field unknown. It is not proof of a 42 mm jaw. The WORKPRO W072016A is 200 mm with a 42 mm jaw at £13.99, used on bath nuts and bike parts around 32–36 mm. The worm opens under load and the serrations mark chrome. The Barpre, £6.49, is 16.1 cm and 35 mm: a tight gap, a poor lever. A 34 mm or 40 mm basin nut may want a tap spanner, with two reviews here, not a reason to skip a set for the rest of the house.

When the combination set earns the space

A set earns the space when 10 mm to 19 mm sizes come back on a bike, flat-pack or in the boot. Hilka is that row, and the comparison's top pick. The bullets skip 7, 9 and 16 mm, and reviews report a missing size. SOL at £4.79 is the best value row and is not this tool: six open-ended pairs from 6 mm to 17 mm, and no ring. Reviews say the jaws slip on anything tight.

A recommendation with a condition

Known metric sizes you will see again: count a Hilka rack, and keep a Stanley 200 mm for the nut the set misses. Older AF or Whitworth is a different system, on metric or imperial spanners. Unknown or oversized: start with a jaw printed in millimetres. WORKPRO's 42 mm when the gap is short. Stanley's 200 mm when the job is general and you accept the field clash. Do not start with SOL on a tight bolt, or with a lone 13 mm ratchet. Hilka's 4.5 from 3,955 ratings does not erase a missing size, and the Stanley's 8 inch field is not a measured opening.

Common questions

Will one adjustable replace a combination set?
It will cover odd sizes, and it will not match a ring on a tight bolt you meet every month. The moving jaw limits the grip, which is why UK guides treat it as a weak way to tighten a small fastener hard. Reviews on this shelf describe worms that open under load. Keep the adjustable for the unknown nut, and the set for sizes that repeat.
When is the ring end worth the extra tool?
When the fastener is tight and you have room to get the ring on. A ring surrounds the nut and, on a 12-point pattern in general, needs less swing to take a new bite than an open end. This file does not say the Hilka rings are 12-point, so do not buy the set for that geometry. Buy it for a fixed jaw of a size you will see again.
Is an open-ended set the same as a combination set?
No. A combination tool has an open end and a ring of the same size. SOL's £4.79 set is double-ended open spanners in pairs from 6 mm to 17 mm. A highlight calls them combination spanners. The title and the pieces do not. You can start a light bolt with them.
Which is better under a sink?
A wide-jaw adjustable is the better reach for a large bath or drain nut in a short gap, as with the 42 mm WORKPRO, and it is still less rigid than a ring. A combination set is better for the ordinary metric hexagons you can get a ring onto. A specialist tap spanner is a third option for 34 mm and 40 mm heads, with only two reviews here.
What if I only own the sizes I meet once?
Then a full rack is wasted space, and one adjustable with a printed jaw is the sensible first tool. The moment a size becomes a habit, a fixed spanner of that size is more secure than resetting a worm. Buy the size you have now measured, not an 11-piece set for one furniture bolt.
Does a ratchet spanner change the choice?
A ratchet of one size does not replace either tool. The Ginddy listing is 13 mm only, with no star rating in the file. It can be handy on that size in a tight swing if the mechanism matches the bullets, which nobody in this file has confirmed. It does not cover a bath nut, and it is not a combination set.
