Best disc padlock

Updated: October 2026

You want one round lock for a shed hasp, a storage latch or a gate, and every amazon.co.uk title says heavy duty. The best disc padlock in this set is the one whose shackle fits that metal. The comparison’s top pick is the Burg-Wächter Circle 21, and the best value is the QWORK one-pack. Prices and stars are the listings on 19 October 2026, on the [disc padlock comparison](/hub/door-and-window-security/disc-padlock). How a grade differs from a maker’s score is on the [disc padlock buying guide](/hub/door-and-window-security/disc-padlock/sub/disc-padlock-buying-guide). Peter F. checked those listings.

Best for a shed hasp you can measure

If you can measure the staple, the ABUS 220/70 states the opening: 70 mm, a 10 mm shackle, 17 mm of clear height, 19.5 mm of clear width, about £19.60, 4.5 from 135 reviews. Two keys, no manufacturer guarantee, and level 7 is ABUS’s own scale. Skip it above about 17 mm or if a policy names a CEN mark. The Master Lock M40, about £13.95 and 4.4 from 1,051 reviews, is the four-key alternative. A beach hut seized one within about a year.

Best when the budget stays under £10

Under £10 you are buying the shape, not a printed grade. The Burg-Wächter Circle 21 is the top pick: about £7.45, 70 mm, 4.6 from 909 reviews, with only one United Kingdom review in the file. That person left it outside through a winter and found a motorcycle chain tight. The shackle is stated as both 9 mm and 10 mm. The ASelected, about £6.61, has locks that opened by hand. The QWORK one-pack at about £5.99 is the best value, a light gate lock whose 1,800-review count matches the two-pack. It is a poor stand-in for a shed full of tools. Where the places diverge is on disc padlock for a shed.

What not to call the best

The Yale Y112 mentions EN 12320:2012 and states no grade. It is 40 mm, a 7 mm shackle, 24.8 mm by 20 mm of clearance, 3.6 from 77 reviews, about £7.44. Buy it only when a 70 mm throat will not close. The Yale Y130B is about £23.86 with 4.6 from 33 reviews, an open-shackle colour field, 0 mm of clearance and a listed 115 g beside a 74 mm body. Skip the OGMBI six-pack, 2.8 from 13 reviews, until you test every lock, and skip the HORAN HOQI at about £4.69, with a 10 g cube that cannot be a 70 mm lock.

A pick only with a condition

Choose the ABUS 220/70 when the staple accepts about 17 mm and a 10 mm shackle and nobody has asked for a printed grade. Choose the Master Lock M40 when you want four keys around £14 and the lock will not sit in salt air. Choose the Burg-Wächter when the budget stays under £10 and you will check the shackle line. Choose the QWORK one-pack only for a gate you can check. Choose an open shackle, or a lock from outside this set, when the chain is thick or the policy names a grade.

Common questions

What is the best disc padlock for a shed?
In this set, the ABUS 220/70, if your hasp accepts roughly 17 mm of clear height and a 10 mm shackle. It is about £19.60 and 4.5 from 135 reviews. It is the wrong pick if you need a CEN or Sold Secure mark, because this listing does not show one.
Is the Master Lock discus good enough?
The M40 at about £13.95 is good enough for many shed bolts and storage latches, with 4.4 from 1,051 reviews and four keys. It is a weaker choice on a beach hut. One review describes a lock that rusted solid within about a year. The 8/10 is not a CEN grade.
Is ABUS worth more than Master Lock here?
It is worth the extra when you want a stated 10 mm shackle and a published clearance, and you are comparing about £19.60 with about £14. It is not worth it when you need four keys, or when the staple is taller than 17 mm and the Master Lock’s opening is the one that fits. Neither listing prints a CEN grade.
What is the best cheap disc lock?
The Burg-Wächter 70 mm at about £7.45, with the limit that only one UK review text is in the file and the shackle is stated as both 9 mm and 10 mm. The cheaper ASelected has reviews of locks that opened by hand. The QWORK at about £5.99 is the best value, a light gate lock, not the shed pick.
Should I buy the six keyed-alike pack?
Not on the claim alone. The OGMBI pack is 2.8 from 13 reviews, and UK reviewers disagree about whether one key opens all six. If you already have it, test every lock inside the returns window before you fit a row of sheds.
Is the small Yale a high-security lock?
The 40 mm Y112 mentions an EN 12320:2012 test and does not give the grade. The shackle is 7 mm and the score is 3.6 from 77 reviews. More clearance is the useful part. The grade is not.
Which lock should I skip?
Skip the OGMBI six-pack as a keyed-alike set, the HORAN HOQI listing until the size lines make sense, and the ASelected if you cannot test that it latches. Skip any 70 mm discus that will not close on your staple, and skip the whole set when a contract names a grade none of these boxes show.
