uxcell M3x5.5mmx2mm Zinc Plated Square Nuts Bronze Tone 100pcs

Description

Product Overview

The uxcell M3x5.5mmx2mm square nuts are precision‑engineered fasteners designed for demanding applications where space is limited and reliability is paramount. Each nut features a zinc‑plated finish with a distinctive bronze tone that not only enhances aesthetic appeal but also provides a robust barrier against moisture and corrosive environments. The compact 2 mm height (0.08″) allows these nuts to sit flush against mating components, making them ideal for printed circuit board (PCB) assemblies, enclosure panels, and other low‑profile installations.

Manufactured to exacting standards, the nuts conform to a thread size of M3 (3 mm diameter) with a square profile measuring 5.5 mm on each side. The material composition is high‑grade metal, further protected by a zinc plating process that meets industry‑wide corrosion‑resistance specifications. Each package contains 100 pieces, with a tolerance of ±2%, ensuring you have a reliable supply for both prototype builds and production runs.

Quality control is a cornerstone of the uxcell brand. Every batch undergoes rigorous testing for dimensional accuracy, tensile strength, and plating adhesion. The result is a fastener that consistently meets the expectations of engineers, hobbyists, and professional assemblers alike. The bronze tone finish also offers a subtle visual cue that helps differentiate these nuts from standard zinc‑only fasteners during inventory checks and assembly line operations.

Beyond the technical specifications, these square nuts provide practical benefits that translate into real‑world value. Their low profile reduces the risk of interference with adjacent components, while the square shape distributes load more evenly than traditional hex nuts, minimizing stress concentrations and extending the lifespan of the joint. The 100‑piece bulk packaging is designed for easy handling, with a resealable bag that protects the nuts from dust and mechanical damage during storage and transport.

Usage

These square nuts excel in a variety of environments, from consumer electronics to industrial automation. In electronics, they are frequently used to secure mounting brackets, heat‑sink assemblies, and connector housings where a low‑profile fastener is essential to maintain clearances and thermal performance. Their corrosion‑resistant coating makes them suitable for outdoor or marine applications, such as securing enclosures for sensor arrays or control panels exposed to humidity.

Robotics enthusiasts appreciate the combination of strength and compactness, using the nuts to attach motor mounts, gearboxes, and structural frames. The bronze tone finish also provides a visual contrast that aids in quick identification during rapid prototyping sessions. For DIY hobbyists, the nuts are perfect for building custom enclosures, mounting LED panels, or creating modular furniture where a discreet fastening solution is desired.

When assembling PCBs, the square shape offers a larger bearing surface compared to hex nuts, reducing the likelihood of stripping the threads in delicate board materials. This is especially valuable in high‑vibration environments, such as automotive or aerospace prototypes, where the integrity of the fastened joint must withstand constant motion and temperature fluctuations.

Installation is straightforward with standard M3 screws or bolts. The square profile aligns easily with a screwdriver or Allen wrench, providing a secure grip that minimizes slippage during tightening. The zinc‑plated coating ensures that the nuts remain functional even after repeated removal and re‑installation, a common requirement in testing and iterative design processes.

FAQ

What is the thread size and pitch of these nuts?

The nuts have an M3 thread size with a standard 0.5 mm pitch, compatible with most M3 screws and bolts used in electronics and mechanical assemblies.

Are these nuts suitable for outdoor or marine environments?

Yes. The zinc‑plated bronze tone coating provides excellent corrosion resistance, making the nuts appropriate for outdoor, marine, and high‑humidity applications.

Can I use these nuts with a standard hex driver?

While a square‑head driver offers the best torque transfer, a standard hex driver can be used if it fits the square profile snugly. For optimal results, we recommend using a driver designed for square fasteners.

How many nuts are included in each package?

Each sealed bag contains 100 square nuts, with a tolerance of plus or minus two pieces, ensuring you have a sufficient quantity for most small‑to‑medium projects.

Do these nuts meet any industry standards?

Yes, they conform to ISO metric thread standards for M3 fasteners and are manufactured under ISO‑9001 quality management processes.
