How to Choose the Right Excavator Tooth Pin for Your Machine: A Guide for U.S. Buyers

When it comes to keeping your excavator performing at its best, there’s one small but mighty part that often gets overlooked: the excavator tooth pin. Whether you're running a CAT, Komatsu, Hitachi, Volvo, or Hyundai machine, the right tooth pin ensures your bucket teeth stay firmly in place—even under the toughest digging conditions.

In this guide, we’ll walk through how to choose the right excavator tooth pin for your brand and application, what materials and specs matter, and why sourcing from a reliable China supplier can save you both time and money.

What Is an Excavator Tooth Pin, and Why Does It Matter?

An excavator tooth pin (sometimes called bucket tooth pin or locking pin) is a critical fastener used to secure the bucket teeth to the excavator adapter. Without a properly fitting, durable pin, your teeth may loosen during operation—causing wear, downtime, or even damage to the bucket itself.

These small pins must handle intense force, vibration, and environmental wear. That's why material strength, precision fit, and anti-corrosion properties are key factors in pin selection.

Common Tooth Pin Models by Excavator Brand

Here’s a quick list of popular models and compatible brands we manufacture:

• CAT (Caterpillar): 1U3352, 9J2358, 6Y3228 pins

And hey, if you don’t see your model above—just ask. We probably got it.

Key Factors to Consider When Buying Tooth Pins

Not all tooth pins are made equal. Here’s what smart U.S. buyers look for:

1. Material Quality

The best pins use heat-treated alloy steel or 40Cr, providing high hardness and durability. Avoid pins that use low-carbon steel or poor finishing.

2. Precision Machining

We use CNC machining and strict QC to ensure exact fit for all common brands. Loose or off-spec pins lead to failure during excavation.

3. Anti-Rust Coating

Especially in humid or coastal job sites, galvanized or painted pins offer longer service life.

4. Ease of Installation

Some tooth pins come with lock rings or spring retainers, making field replacement fast and easy. No one likes wasting hours on what should take five minutes.
