New 3DS Screw and Hardware Measurements

KIlly728 · Feb 15, 2025

Continuing in my series of screw measurement posts, we come to the New 3DS.

I've done screw measurement posts for several consoles (listed below), including every DS and 3DS console.

I did deeper dives into the DSi and DSi XL, pointing out any console-to-console differences.

I have since updated this post with measurements from calipers. My original post will be buried within this spoiler tag.

How I measured these screws.

I measured the screws on a ruler with markings down to half-millimeter increments and a digital microscope. Measurements were taken similar to this image of measuring Thread Pitch below.

(Image Sourced from Albany County Fasteners' video, How to Measure Screws & Bolts - US & Metric Sizing | Fasteners 101)

Since I do not have specialty equipment to measure screws this small, I am forced to estimate; especially on the thread pitch itself. Take the measurements with the knowledge that it was done by someone who is a novice in screw measuring.

New 3DS

All Screws within the New 3DS have a JIS head (I assume JIS #00), but a Phillips #00 works. The Battery Door can be opened with a #00, but a #0 fits better.

There are three Tri-Wing screws. I suppose there is a JIS equivalent, but I haven't looked into it. IFixIt recommends the use of a "Y0" Tri-Wing driver. The Tri-point bit I used had a different measuring scheme and a Y1.5 worked for me (not sure why, but that isn't important). I believe the Y1.5 is equivalent to a Y00 which, again, worked for me.

Below is the list of screws and Hardware grouped by size.

I'll add links to an IFixIt Guide to match my terms to pictures (i.e. Motherboard Screw would point to the Motherboard removal step of an IFixIt guide). The screw names themselves will have a link to the image of the screw removal with another link next to it just in case that link dies.

How I Measure Screws.

I will use a custom chart I made as a reference to measure each screw with my calipers.

Measurements done with Calipers will only be done on one screw per category, and will be subject to some amount of inaccuracies due to the size of the screws and the tools I have. Measurements like Thread Pitch, Shank Length, Thread Length, and Recess Width are done by eyeballing it with my calipers and a microscope. Measurements like Thread Diameter and Screw Length will be far more accurate as I can physically clamp them in my calipers.

Resources, Set Up, and Drivers.

Screws will be sorted by size, going from shortest to longest, rounded to the nearest 0.5mm. In the cases where screws weren't rounded to the whole or half steps, I found their measurements consistent with other screws of the same category, thus, were labeled with their non-standard measurement.

I'll add links to an IFixIt Guide to match my terms to pictures (i.e., Motherboard Screw would point to the Motherboard removal step of an IFixIt guide). If there is no guide, I won't be able to link.

The New 3DS guides on IFixIt are not complete as they do not include a step for removing the Top Screen. The drivers recommended in the guide match my experience, so I have nothing to say there.

The only gripe I have with the guides is that the Motherboard removal step says there are three screws; however, there aren't. The screw circled on the top right, next to the top display and camera ribbon connector, is a through hole for one of the bottom shell screws. Screwing a motherboard screw there MAY be ok, but what it will do is plug the hole for the screw that belongs there.
