7-string Titanium Alloy Fanned-fret Headless Guitar String Lock

In this review the focus is on a replacement string lock designed specifically for 7-string headless electric guitars with a slanted fret bridge. The bottom line: this titanium alloy string lock is aimed at players who want a lightweight, hard-wearing replacement that preserves string alignment on fanned-fret headless instruments. It stands out because the titanium material delivers much greater hardness and lower weight than comparable zinc-alloy parts, while the open-threading and anti-cut design address common usability and durability problems for frequent players and techs.

Key Features

• Titanium alloy construction: provides a high strength-to-weight ratio so the lock is sturdy yet significantly lighter than zinc-alloy alternatives.
• Fanned-fret compatibility: the 13 degree angular tilt and 7mm string spacing are tailored to 7-string headless guitars with a slanted fret bridge for correct string alignment.
• Open string-threading holes: let you see the string position clearly during installation and reduce the risk of strings protruding and stabbing fingers.
• Anti-cut clamping system: the screw presses a round copper plate onto the string to avoid cutting the string edge when tightened, improving string life.
• Includes hardware: ships with the installation screws and parts needed, making replacement straightforward for most techs and DIYers.
• Compact footprint: the lock measures approximately 39mm x 28.5mm x 6mm, fitting headless bridges where space is limited.

Who It's For

This string lock targets players who own 7-string headless electric guitars with slanted or fanned-fret head geometry and need a reliable replacement part. It is especially useful for touring musicians or builders who prioritize reduced weight and a high-hardness component to reduce wear under heavy use.

Players with standard 6-string headless guitars, basses, or instruments using non-slanted bridges should look for the correct size or a different product variant; also those who require brass or chrome finishes should consider the other materials and colors in the same product family.

Pros & Cons

• Includes installation hardware so the part can be fitted without sourcing extra screws.

Cons
