MCMASKE Metric Starlock Washers Kit 300pcs M3 to M12 with Push Rings

Description

Product Overview

The MCMASKE Metric Starlock Washers Kit is engineered to meet the demanding requirements of modern industrial equipment. Each of the 300 pieces is manufactured from high‑grade carbon spring steel that undergoes a blackening surface treatment, delivering a dark, uniform appearance while providing mild corrosion resistance. The internal tooth design of the washers ensures a secure lock on unthreaded shafts, preventing axial movement under vibration and shock loads.

Designed for versatility, the kit includes washers ranging from M3 to M12, external push rings, and push‑on nuts that enable rapid assembly without the need for additional tools. The components are packaged in a clear, compartmentalized plastic box that allows quick visual identification and easy access, reducing downtime during maintenance or installation. The magnetic properties of the steel further simplify handling, as the pieces can be quickly gathered with a simple magnet.

Technical specifications highlight a compact package dimension of 5.98 × 3.98 × 0.83 inches and a lightweight of 6 ounces, making storage and transport straightforward. The product model number QSZCJM3-M12300P and the manufacturer MCMASKE are clearly marked for traceability. With a best‑seller rank of #54 in the Tooth Lock Washers subcategory, the kit has earned a solid reputation among professionals.

Beyond the core components, the kit’s design emphasizes user‑friendly features such as the push‑on mechanism that eliminates the need for torque wrenches, allowing technicians to secure fasteners quickly and reliably. The external push rings provide additional flexibility for applications requiring a larger bearing surface or a different load distribution. This comprehensive assortment makes the kit a one‑stop solution for a wide range of mechanical and industrial tasks.

Usage

These starlock washers excel in environments where vibration and shock are prevalent, such as automotive assemblies, heavy‑duty machinery, and precision equipment. The internal tooth profile grips the shaft firmly, making them ideal for securing bearings, pulleys, and gear assemblies that experience frequent motion. The push rings and nuts are particularly useful for applications involving unthreaded shafts, where traditional threaded fasteners cannot be employed.

In manufacturing settings, the kit supports rapid line changes and equipment upgrades by providing a ready supply of standard sizes. Maintenance crews benefit from the clear packaging, which reduces the time spent searching for the correct washer size, thereby improving overall efficiency. The magnetic nature of the steel also aids in keeping work areas tidy, as stray pieces can be quickly collected with a magnet.

For hobbyists and small‑scale workshops, the kit offers a cost‑effective way to stock essential fasteners without compromising on quality. Whether assembling a custom CNC machine, repairing a small motor, or building a prototype, the versatility of the included components ensures that users have the right part on hand for a variety of shaft diameters and load conditions.

FAQ

What sizes are included in the kit?

The kit contains washers sized from M3 up to M12, covering the most common metric dimensions used in industrial and mechanical applications.

Can these washers be used on threaded shafts?

While the internal tooth design is optimized for unthreaded shafts, the washers can also be applied to threaded shafts where a lock function is needed, provided the thread does not interfere with the tooth engagement.

Is the black finish durable in harsh environments?

Yes, the blackening treatment provides a protective layer that resists mild corrosion and wear, making the washers suitable for outdoor or chemically exposed settings.

How does the magnetic property benefit installation?

The magnetic nature of the carbon steel allows technicians to quickly gather and position washers using a simple magnet, reducing the chance of losing small components during assembly.

What warranty does MCMASKE offer?

MCMASKE provides a one‑year limited warranty covering material defects and workmanship, backed by responsive technical support to address any concerns.
