Description
Product Overview
Our 12‑piece set of coarse square nuts is engineered for demanding environments where strength, durability, and reliability are non‑negotiable. Each nut is forged from high‑grade alloy steel, a material known for its superior tensile strength and resistance to deformation under load. The zinc coating applied to every piece adds a robust barrier against moisture, chemicals, and everyday wear, extending the service life of the fastener and protecting the surrounding assembly from corrosion.
The 7/16‑14 inch thread size conforms to the Unified National Coarse (UNC) standard, ensuring compatibility with a wide range of bolts, studs, and threaded rods commonly used in industrial machinery, automotive repair, and construction projects. The square profile of the nut distributes load more evenly across the fastening surface, reducing the risk of rounding or stripping the threads during tightening. This design also provides a larger bearing area, which is especially beneficial when fastening thick or heavy components.
Every nut in this collection meets Class 2A thread tolerance, delivering a precise fit that minimizes play and maximizes torque transfer. The nuts are packaged in a compact, single‑package quantity that simplifies inventory management for workshops, maintenance teams, and hobbyists alike. With a total weight of approximately 0.22 kilograms (7.7 ounces), the set is lightweight enough for easy handling yet substantial enough to convey the solid construction of each component.
Our brand, Hard-to-Find Fastener, has a reputation for supplying niche, high‑quality fasteners that are often unavailable through mainstream distributors. This commitment to sourcing and delivering specialized hardware means you can trust each product to meet exacting standards without compromise. The inclusion of a clear UPC (014973401283) and ASIN (B00OOYZJ72) further streamlines ordering and inventory tracking for businesses that rely on accurate part identification.
Whether you are assembling a new piece of equipment, repairing an existing system, or undertaking a custom fabrication project, these coarse square nuts provide the confidence that comes from using a fastener built to perform under pressure. Their versatile size and finish make them suitable for a broad spectrum of applications, from heavy‑duty industrial rigs to precision‑engineered prototypes.

Usage
In industrial settings, these nuts excel when used to secure structural frames, motor housings, and gear assemblies where vibration and cyclic loading are common. The zinc plating helps prevent rust in environments with exposure to oil, coolant, or outdoor elements, making them ideal for agricultural machinery, construction equipment, and marine applications.
For mechanical workshops, the 7/16‑14 thread size aligns with many standard bolts and studs, allowing technicians to quickly replace worn or damaged fasteners without the need for custom machining. The square shape offers a larger contact surface, which is advantageous when fastening thick plates or components that require a high degree of torque without compromising thread integrity.
DIY enthusiasts will appreciate the ease of installation and the reliable grip these nuts provide. Whether building a custom workbench, fabricating a metal art piece, or repairing a home appliance, the nuts’ robust construction ensures that the finished project remains secure over time. Their moderate weight and compact packaging also make them convenient to store in a personal toolbox or workshop drawer.

FAQ
What does the zinc finish protect against?
The zinc coating acts as a sacrificial barrier that resists moisture, chemicals, and atmospheric exposure, helping to prevent rust and corrosion on the steel core of the nut.
Are these nuts compatible with metric bolts?
While the nuts are sized to the Unified National Coarse (UNC) standard, they can be used with metric bolts that have a close equivalent diameter, though a precise fit is best achieved with matching UNC threads.
Can I use these nuts in high‑temperature environments?
The alloy steel core can tolerate moderate temperature ranges, but extreme heat may affect the zinc coating. For applications above 300 °F (149 °C), consider a fastener with a heat‑resistant coating.
How many pieces are included in the package?
The package contains twelve individual coarse square nuts, each sized 7/16‑14 inch, providing enough quantity for most small to medium‑scale projects.
What is the thread class and why does it matter?
These nuts are Class 2A, which means they have a standard tolerance that offers a reliable fit with Class 2B bolts, ensuring consistent torque transfer and minimizing play.
