4 Piece Golf Weight Screws for Mizuno ST-200G/ST-190G/ST-G Driver – 5g 7g 9g 11g – Black

Customize your Mizuno driver with precise weight screws

This 4-piece weight screw kit is designed to slot into compatible Mizuno drivers, letting you experiment with swing weight and feel. By swapping in different weights, you can explore how small changes in mass may influence ball flight, trajectory, and overall confidence at address. The set includes four distinct grams—5g, 7g, 9g, and 11g—for a wide range of tuning options without changing your shaft or grip.

What’s included and what you can adjust

• Weights: 5g, 7g, 9g, and 11g to support a spectrum of tuning possibilities
• Compatibility: Fit for Mizuno ST-200G, ST-190G, and ST-G drivers (note: not compatible with ST-G 440)

How it helps on the course

While you cannot guarantee performance gains, these weights offer practical ways to customize your setup. Depending on conditions and your swing tempo, you may observe more stability, improved feel at impact, or a different ball flight with each weight change.

• Heavier weights can contribute to a steadier feel during full swings and windy conditions
• Lighter options may support a quicker, more responsive feel and easier launch

The screws sit flush in the driver’s weight ports, ensuring a clean look at address and minimal distraction during the swing. A durable finish helps reduce glare through sunlight and practice sessions.

Easy to use and store

The kit is compact and simple to install—no shafts or grips required. Four screws give you the freedom to try different combinations across rounds and practice sessions, all without tools beyond a standard wrench included with your club’s maintenance kit (or your own torque-safe method).
