369DRONE Titanium Button Head Screw (M3 x 10mm) Review
A titanium button head screw, M3 x 10mm, listed for the PRO Trinity at $2 with a quantity of x4. It suits someone who needs a repair or spare screw of that size for the PRO Trinity; the listing gives no weight or thread detail.

Our verdict
For someone who needs a titanium M3 x 10mm button head screw listed for the PRO Trinity, at $2 with a quantity of x4. Look elsewhere if you need another length or head shape, a weight or thread figure, or a fit with anything other than the PRO Trinity. The main caveat is the short text: the listing says titanium balances low weight and strength, with no figure given for either.

Listed for the PRO Trinity, this is a titanium button head screw in size M3 x 10mm, priced at $2 as a single option with a quantity of x4. The page is short: it names the material, head shape, size and fit, and repeats the fit under Compatibility. It gives no weight, thread pitch or head diameter.

Options and pricing
One option, priced at $2, with a quantity of x4. The size is M3 x 10mm and the material is Titanium, with no choice of color or head shape. Other lengths, such as M3 x 12mm and M3 x 6mm, appear as separate listings.
How it compares
The Titanium Button Head Screw (M3 x 12mm) is also $2 and lists its fit as Trinity / TUF Trinity, where this M3 x 10mm screw lists PRO Trinity. The Titanium Button Head Screw (M3 x 6mm) is $3 and shows no fit line. The Titanium Flat Head Screw (M3 x 10mm) for MIROKU PRO Frame is $3 with a flat head and a different frame, so it does not replace this one.
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 $2, 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 the material (Titanium), the head shape (button head) and the size (M3 x 10mm)
- The fit is named, PRO Trinity, and repeated under Compatibility
- A single option at $2 with a quantity of x4
Worth noting
- The listing gives no weight, thread pitch or head diameter for the screw
- It names only PRO Trinity, so nothing is said about any other fit
- The listing says titanium balances low weight and strength but gives no figure for either
