🎾 How to Identify Your Guitar Tuner Mounting Style: Screw, Dual-Pin, or Push-In?

Before replacing your tuning machines, it's crucial to know your guitar's tuner mounting type. Choosing the wrong structure could lead to misalignment, drilling issues, or even irreversible damage to your headstock. In this guide, we’ll walk you through the three most common types of tuner mounting systems—Screw Mount, Dual-Pin (No Screw), and Push-In Style—to help you find a compatible upgrade without any hassle.

đŸ› ïž 01Screw Mount Tuners: The Most Common Style

This is the most widely used mounting type. These tuners come with a small screw hole on the back, which secures the tuner directly to the headstock.
We categorize them by screw hole direction:

đŸ”č Vertical Screw Mount

  • Screw hole located straight beneath the tuner housing
  • Aligned vertically with the tuner post
  • Common on many modern electric guitars
  • Example models: GK-D-502SP, GK-D-504SP

đŸ”č Angled Screw Mount

  • Screw hole sits at the lower-right corner (~45° angle)
  • Offers a sleek, angled alignment with the headstock
  • Often found on boutique or modified builds
  • Example models: GK-D-07SP, GK-D-05SP
✅ Best choice if your original tuner uses rear screws. Just match the orientation.

📎 02Dual-Pin Mount: No Screws, Cleaner Look

Instead of a screw, this system uses two small alignment pins on the tuner base, which fit into pre-drilled holes on the back of the headstock. No visible screws, no tools required for installation.

🔾 Features:

  • Screw-free appearance on the back
  • Quick installation
  • Pins ensure alignment and anti-rotation
  • Popular on Gotoh, Ibanez, ESP guitars
  • Example models: GK-D-405SP, GK-D-434SP
✅ Recommended if your original tuners had two small holes and no screws.

đŸ”© 03Push-In Style: Pressure-Fit Only

This mount style relies solely on a press-fit system via the front bushing and headstock hole. There's no screw or pin at the back.

🔾 How to tell:

  • No screw or pin on tuner base
  • Tuners are pulled straight out (not unscrewed)
  • Fitment depends on exact peg hole diameter
❗ Requires precise measurements. Not all guitars are compatible without slight modifications.
