20/410 Neck: the Travel and Mist Size
By Joe Joo · 8PCK · Shantou · Updated 26 October 2026
20/410 sits between the dropper neck and the standard pump neck: fine mist sprayers, travel flip-tops and 50–100 ml bottles.
20/410 is 20 mm with a 410 thread. It is the size that makes a 50–100 ml bottle look right with a mist sprayer or a disc-top, where an 18 mm would look fragile and a 24 mm too heavy.
The free Bottle Spec Checker tests whether your neck fits the closure and whether the wall survives a pump stroke.

What Fits A 20/410
Fine mist sprayers, flip-tops, disc-tops and small pumps. It is the travel and perfume-sample neck.
Fine Mist Sprayer
The classic 20/410 use: perfumes, toners, sanitizers.
Flip or Disc Top
Travel packs and samples where a sprayer is unnecessary.
Why Not 24/410 at This Size
A 24 mm closure on a 50 ml bottle makes the pack look top-heavy and the label area disappears. 20/410 keeps the proportion.
Where It Fails
Mist sprayers set for water spray a toner coarsely. Test the sprayer with the real liquid, not with water.
How to Confirm the Neck Before Ordering
The 20/410 code is a diameter plus a thread profile, and both have to match for travel packs and mist sprayers.
Measure T, E and H
T is thread height, E is the gap between threads, H is the height to the sealing surface.
Send the Closure
A pump that fits a drawing can leak on a bottle. Test the pair, not the part.
Check the Drawing, Not the Photo
Two bottles can look identical and differ by 5 mm of thread.
What to Send in a Brief
Neck (20/410), bottle capacity, closure model and quantity. With those four we confirm fit before quoting.
