Choosing the Right Screw for Hair Shears: A Guide to Precision & Performance

Introduction

When purchasing professional hair shears, hairstylists often focus on blade type, handle design, and steel quality. However, one critical yet frequently overlooked factor is the screw system. The screw determines tension control, cutting accuracy, and overall shear performance.

Selecting the wrong screw can lead to loose blades, misalignment, and inconsistent cuts. In this guide, we’ll explore different screw types, their benefits and drawbacks, and how to pick the best one for your needs.


Why Is the Screw System Important in Hair Shears?

The screw system holds the two blades together, allowing them to pivot smoothly. A properly adjusted screw provides:

Precision cutting – Keeps the blades aligned for sharp, clean cuts.
Effortless cutting motion – Prevents hair from folding or slipping.
Reduced hand fatigue – Ensures smooth gliding with minimal resistance.
Extended shear lifespan – Minimizes unnecessary wear and tear.

A low-quality or poorly adjusted screw can loosen over time, affecting the shear’s cutting performance. That’s why understanding screw systems is essential.


Types of Screw Systems in Hair Shears

There are three primary types of screws used in professional hair scissors:

1. Flat (Standard) Screw

Features:

  • Traditional flathead screw design.
  • Requires a screwdriver or tool for adjustment.
  • Found in entry-level and mid-range hair shears.

🔍 Pros: Simple & durable – Less likely to break.
Holds tension well – Stays tight for long periods.
Affordable – Common in budget-friendly shears.

Cons: Requires a tool – Not convenient for quick adjustments.
Limited flexibility – Not ideal for hairstylists who frequently modify tension.

💡 Best For: Beginners, barbers, and stylists who don’t adjust tension often.


2. Adjustable (Hand-Tighten) Screw

Features:

  • Also known as a click or dial screw.
  • Can be adjusted by hand (no tools needed).
  • Found in high-end professional shears.

🔍 Pros: Easy to adjust – No screwdriver required.
Click system – Provides precise tension control.
Smooth operation – Allows stylists to fine-tune their shears for different techniques.

Cons: More expensive – Typically found in premium shears.
May loosen over time – Requires regular tension checks.

💡 Best For: Professional hairstylists who frequently adjust tension for different cutting styles.


3. Ball Bearing (Advanced) Screw

Features:

  • Contains tiny ball bearings inside the mechanism.
  • Reduces friction and improves blade stability.
  • Used in high-end ergonomic shears.

🔍 Pros: Ultra-smooth cutting – Blades move effortlessly.
Even wear distribution – Increases shear lifespan.
Holds tension longer – Requires fewer adjustments.

Cons: Expensive – Found only in top-tier shears.
Difficult to replace – Custom parts may be needed.

💡 Best For: Advanced stylists looking for ultra-smooth shears with minimal maintenance.

🔹 If you need precise tension control, go for an adjustable screw.
🔹 If you want the best performance, invest in ball bearing screws.


Common Mistakes When Choosing a Screw System

Even experienced hairstylists overlook the importance of a good screw system. Here’s what to avoid:

Mistake #1: Ignoring the Screw System

Many stylists focus on the blade type but forget to check the screw’s quality.

🔹 Solution: Always check if the shear has a reliable tension system that fits your cutting style.

Mistake #2: Choosing a Non-Adjustable Screw Without Considering Future Needs

A beginner might start with a flat screw, only to later regret not having an adjustable screw for more control.

🔹 Solution: If you plan to advance in hairstyling, choose a shear with an adjustable or ball bearing screw.

Mistake #3: Over-Tightening the Screw

Too much tension can increase blade wear and cause hand strain.

🔹 Solution: Adjust tension gradually, ensuring the blades close smoothly without resistance.


How to Adjust the Screw on Hair Shears Properly

No matter what screw type your shears have, proper adjustment is key to optimal performance.

Step-by-Step Guide to Adjusting Shear Tension:

1️ Check the tension: Open the shears and let one blade drop.

  • If it slams shut, the tension is too loose.
  • If it doesn’t move, the tension is too tight.

2️ Adjust gradually: Turn the screw clockwise to tighten or counterclockwise to loosen in small increments.

3️ Test the cut: Try cutting a piece of tissue. If it folds or pulls, the tension is incorrect.

4️ Maintain regularly: Check tension weekly to ensure smooth operation.


Conclusion

The screw system plays a crucial role in cutting accuracy, ease of use, and shear longevity. Choosing the right screw type can make a significant difference in your hairstyling experience.

🔹 For beginners, flat screws are durable and simple.
🔹 For professionals, adjustable screws provide flexibility.
🔹 For advanced stylists, ball bearing screws offer the smoothest cut.
