369DRONE Plastic Nut (M3) Review
A $1 set of M3 nylon nuts that the listing describes as non-conductive and meant for FC and ESC stack mounting, with 4 pieces per set. It suits a builder who wants nuts for that job, though the listing gives no weight or dimensions beyond M3.

Our verdict
A $1 set of four M3 nylon nuts for a builder who wants non-conductive nuts for an FC and ESC stack, as the listing describes them. Look elsewhere if you need a different material or size, a stated nut height or weight, or a named frame other than the MIROKU series. The main caveat is that the short-circuit and grip statements are the listing's own.
- Best for
- Someone mounting an FC and ESC stack who wants four M3 nylon nuts for $1.
- Skip if
- You need nuts in another material or size, or a listing that gives nut height and weight.
Four M3 nylon nuts make up this $1 listing, which the store titles Plastic Nut (M3). The listing describes them as non-conductive and aimed at mounting flight controllers, ESCs and other electronics, and it names MIROKU series builds and other standard stack setups as compatible. There is one option, and the set holds 4 pieces.
Options and pricing
There is one option, a single variant at $1 for a set of 4 pieces, so the price does not change by size or color. The title gives M3 as the size and the text names nylon as the material. No other sizes, colors or pack counts appear on the page.
How it compares
The ClinchNut (M3) is listed at $6 against $1 for this nylon set, and the two are different nuts by name, so this page gives no basis for swapping one for the other. The Aluminum Standoff (M3 x 22mm) is $3 and lists aluminum, but a standoff is a different kind of part from a nut. The ClinchNut Press-Fit Tool (M3) is also $1, yet it is a tool rather than a nut.
Shipping and processing
- Processing. The store's shipping policy says every order, including orders placed through the Shop app, ships from its warehouse in Japan and is dispatched within 1-3 business days after payment is confirmed (checked 2026-11-11).
- Shipping cost. The policy gives a flat 800 JPY inside Japan and 5,000 JPY to eligible countries for parcels up to 2 kg, and gives no rate for heavier parcels. It does not list the eligible countries; the store's country selector offers the United States, Canada, the United Kingdom, Australia and New Zealand, and the terms of service reserve the right to limit sales to any region, so the checkout is the final test. At the rate the store used for US prices when we looked (about 0.00642 USD per JPY), 5,000 JPY is about $32; the checkout shows the exact amount.
- Price against shipping. This listing costs $1, less than the flat international shipping fee above. The policy prices shipping per parcel up to 2 kg, so what an order of several small parts pays depends on how the store packs it, and the pages do not say.
- Duties and taxes. The policy says import duties, taxes and customs clearance fees are not included in the price or the shipping cost, are charged to the recipient by the carrier (it names DHL, FedEx and Japan Post) and are outside the store's control. It declares the full value of the goods on customs papers and cannot mark a parcel as a gift or declare less. A parcel held for unpaid duties is not delivered, and if the carrier sends it back the return shipping is deducted from any refund.
- Tracking. A tracking number is issued once the parcel ships. For international parcels it can take a few days to show up, and it can change when the parcel is handed from one carrier to another.
Returns and warranty
- Returns. The store's refund policy gives 30 days after receiving an item to request a return. The item must be in the condition received, unworn or unused, with tags and in its original packaging, and you need the receipt or proof of purchase. Use the contact page first: if the return is accepted the store sends a return shipping label and instructions, and items sent back without a request are not accepted. The policy does not say who pays the return shipping on a change-of-mind return. Refunds go to the original payment method within 10 business days after the store has received and inspected the item (checked 2026-11-11).
- Not returnable. The refund policy lists custom products (special orders and personalized items), perishable goods, personal care goods, hazardous materials, flammable liquids and gases, sale items and gift cards. The legal notice, which is in Japanese, adds made-to-order items, digital downloads once downloaded, and goods whose value was lost through the buyer's use or modification. For an exchange the policy says to return the item and, once the return is accepted, buy the new one separately.
- Damaged or wrong items. The refund policy asks buyers to inspect an order on arrival and to contact the store at once about a defective, damaged or wrong item so that it can evaluate the issue and make it right. The legal notice says the store exchanges or refunds such an item at its own cost.
- Warranty. The shipping policy, refund policy and legal notice describe no warranty, and we found no warranty page. The terms of service say products are provided 'as is' except as the store expressly states, disclaim warranties, and are governed by Japanese law. Many of the parts this store sells are made by other brands; nothing says whether the store or the maker handles a fault that appears after the item has been in use (checked 2026-11-11).
Before you buy
369DRONE describes itself as an FPV racing drone brand from Japan. Its About page says the founder, Daichi Sakakibara, spent over a decade as a test driver at Toyota Motor Corporation and builds products with experience from racing. These are the store's own statements (checked 2026-11-11).
The store is in Japan and quotes yen. The price on this page is its United States dollar price as of 2026-11-11; the store converts at its own rate, which moves, and a visitor in another country can see a different amount or currency.
The legal notice, written in Japanese, says the products are meant for FPV drone racing and hobby use, asks buyers to follow the Aviation Act, the Radio Act and other laws, and says the store takes no responsibility for damage caused by use that breaks the law. Those are Japan's laws. We have not checked what applies where you live and we do not say whether this product can be flown or operated legally in your country.
The English refund policy takes back items that are "unworn or unused", while the Japanese legal notice says, as we read it, unused and unopened, so check the condition rule with the store before opening the package. We have not read any independent review of this product or of the store.
What we liked
- The listing names nylon as the material and M3 as the size, with 4 pieces per set
- The text names FC and ESC stack mounting as the use and MIROKU series builds as compatible
- A single option at $1, so there is no size or color to choose
- The listing describes the nuts as non-conductive, a property it ties to mounting electronics
Worth noting
- The listing gives no weight, thread pitch or nut height
- Compatibility is stated for MIROKU series builds and other standard stack setups, without naming any other setup
- The listing's statements about eliminating short circuits and a good balance of grip and flexibility come with no data
Questions before you buy
What size and material are these nuts?
The title gives M3 and the listing names nylon. The set holds 4 pieces and costs $1.
What does the listing say they are for?
The listing says they are for mounting flight controllers, ESCs and other electronics, and it names MIROKU series builds and other standard stack setups as compatible.
Does the listing give a weight or a nut height?
No. Beyond M3, nylon and the 4-piece count, it gives no measurements.
Can I return it if I change my mind?
The refund policy gives 30 days after receipt to request a return of an unused item in its original packaging, with proof of purchase; contact the store first and wait for its return label. Custom products, sale items and gift cards cannot be returned, and the pages do not say who pays return shipping.
How long and how much to get it from Japan?
The shipping policy says the order ships from Japan and is dispatched in 1-3 business days after payment. International shipping to eligible countries is a flat 5,000 JPY for parcels up to 2 kg (about $32 at the store's US rate); the store's country selector lists the US, Canada, the UK, Australia and New Zealand.
Who pays import duties and taxes?
The recipient. The shipping policy says import duties, taxes and customs fees are not in the price or shipping cost, are collected by the carrier and cannot be predicted by the store. A parcel held for unpaid duties is not delivered, and return shipping is deducted from any refund if the carrier sends it back.

What we couldn’t verify
- The listing calls the nuts lightweight and durable and says they eliminate the risk of short circuits; we could not check these statements, as no data is shown for them.
- The listing says the nuts suit MIROKU series builds and other standard stack setups but names no other setup, so we could not check what else they fit.
- We have not read any independent review of this product or of the store; the About page is the store's own account.
- The English refund policy takes back items that are unworn or unused, while the Japanese legal notice says unused and unopened; we could not tell which rule applies.
- The store's pages describe no warranty and its terms provide goods 'as is'; we could not tell who handles a fault that appears after use.
