StewMac Electric Guitar Neck Shims – Shaped, Set of 3 (0.25°, 0.50°, 1°) – Tapered Maple Shims for Bolt-On Neck Adjustments – Full Contact, Precision Fit – Ideal for Guitar Setup & Repair

StewMac Neck Shims – The Professional Solution for Perfect Neck Angle Adjustments.

For decades, guitar players and repair shops have used makeshift shims—such as matchbook covers or guitar picks—to adjust the neck angle on bolt-on guitars. However, these create gaps under the neck heel, leading to potential humidity issues and a loss of tone.

StewMac’s precision-crafted maple neck shims solve this problem. These full-contact, tapered shims fit the entire heel of the neck, ensuring a solid connection between the neck and body. No more guesswork—these shims provide a professional setup with reliable results.

Three Shims for Perfect Adjustments:

• 0.25° Shim: Ideal for fine-tuning neck angles. Stack multiple shims for customized adjustments.
• 0.50° Shim: The most commonly used shim, perfect for Fender-style guitars and other solid-body instruments.
• 1.00° Shim tapers from 0.060" to 0.010" (1.52mm to 0.25mm), best for guitars with high-action bridges like Tune-o-Matic or Floyd Rose

  Precision Tapering for Consistent Results:

  • 0.25° Shim: 0.030" to 0.019" (0.76mm to 0.48mm)
  • 0.50° Shim: 0.028" to 0.008" (0.71mm to 0.20mm)
  • 1.00° Shim: 0.060" to 0.010" (1.52mm to 0.25mm)

  Designed for Universal Fit: Shaped shims measure 2-3/16" x 3" (55.56mm x 76.12mm) and fit most neck pockets with a rounded heel. For flat-heeled neck pockets, such as Tele-style guitars, simply trim along the lasered guide line.
