I would guess 0 since there is a screw for anti rotation.** A: Lol,I dont know what kind the guy that said 1 pin had cause these dont have any pins.As for strats they are not staggered like Fender strat tuners are from tall to short.They are all the same height so You Must Use String Trees.For looks I would recommend the Fender locking tuners and they are actually cheaper.But if you want the convenient string trimmers they are very nice and have a better gear ratio. **Q: can i apply them without drilling holes ? i mean if i screw hard the top will they move?** A: I would not use them without drilling and installing the tuners with the screw. That screw provides necessary stability. If you don’t want to drill… find tuners exactly like the ones you have… with the hole in the exact position as your old tuners. Then you can install with a minimum of work. Take a photo of your existing tuners and buy good replacements. Make sure you select 3x3 or 6 inline based on what you have, and search online. It’s been my experience you want tuners that are good… and quality starts at $50 and up. **Q: Will these fit a peavey v type guitar?** A: They fit 10mm tuner holes. If your tuner holes in your peg head are smaller you will need to drill them out **Q: 3x3 with offset screw position?** A: You'd need a different setup; the 6 in-line is different height based poles. So essentially they're not designed to "get out of the way" of each other. Now, that's not saying you can't use it, but the heights are not aligned so may be an issue (you may not care about it and depending on the guitar, it may not be a problem). I would look for the correct positioning. ## Frequently Bought Together - D'Addario Accessories Auto-Trim Tuning Machines - Locking Tuners for Guitars - 6 In Line Setup, Black - SAPHUE 3MM Electric Guitar Bass Pickguard Screws Pick Guards Scratch Plate Mounting Screws for Fender Strat ST Tele TL Stratocaster Telecaster Gibson LP Les Paul SG Guitar Pack of 50 (black) - Metallor Guitar Neck Plate Standard 4 Holes with Screws 64mm x 51mm Compatible with Strat Tele Style Electric Guitar Jazz Bass Parts Replacement Pack of 1Set Black. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/4826153-daddario-auto-trim-tuning-machines-locking-tuners-for-guitars-6](https://www.desertcart.jp/products/4826153-daddario-auto-trim-tuning-machines-locking-tuners-for-guitars-6) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-04*
