What Is a Nut and Screw in PV Foundation Systems?
A nut and screw are fundamental fasteners used to secure photovoltaic mounting structures to the ground. In solar projects, these components connect the metal brackets to helical piles or ground screws, ensuring the entire array remains stable under wind and snow loads.
Hebei Shijing Changtian Metal Structure Products Co., Ltd. specializes in manufacturing high-strength nuts and screws designed for harsh outdoor environments. Our products comply with international standards, providing reliable connections that reduce maintenance costs and extend the lifespan of your solar installation.
Why Choose SJCT for Your Solar Fastener Needs?
As a leading manufacturer in Yongnian, Hebei, SJCT leverages a mature industrial cluster to offer cost-effective, high-quality fasteners. With two production bases covering 25,000 square meters, we ensure consistent supply and rapid delivery for large-scale solar projects.
Our commitment to quality is reflected in our ISO 9001, ISO 14001, and ISO 45001 certifications. We use premium materials like Q235B and Q355B steel, combined with hot-dip galvanizing that meets GB/T 13912 standards, guaranteeing corrosion resistance for over 3,000 hours.
Quality & Manufacturing Process
Premium Raw Materials
We source Q235B and Q355B steel, ensuring base material strength exceeds industry averages. Every batch is inspected before production begins.
Automated Production
With 6 automated production lines and over 30 punching machines, we achieve high precision and consistency, reducing manual errors.
Rigorous Quality Control
A full-process self-inspection mechanism verifies dimensions, thread integrity, and coating thickness at every stage of manufacturing.
How to Choose the Right Solar Fasteners
Selecting the right nut and screw involves matching material, size, and corrosion protection to your project's environment. For coastal or high-humidity areas, opt for hot-dip galvanized fasteners with a zinc layer thickness of at least 85μm.
Consider the load requirements of your solar array. SJCT offers customizable solutions, including various thread lengths and diameters, to accommodate different pile types and bracket designs. Our technical team can assist in optimizing your fastener selection for maximum structural integrity.

Common Problems with Solar Fasteners
Corrosion Failure
Low-quality coatings peel off in humid environments, leading to rust and structural weakness. SJCT's hot-dip galvanizing ensures long-term durability.
Thread Stripping
Incorrect material hardness causes threads to strip during installation. Our precise manufacturing guarantees optimal torque resistance.
Dimensional Inconsistency
Non-standard sizes create fitting issues on-site. Automated production minimizes variance, ensuring perfect compatibility.
Supply Delays
Small suppliers often struggle with large orders. SJCT's 25,000㎡ facilities and 3 million piece annual capacity prevent bottlenecks.

Frequently Asked Questions
What materials are best for solar nut and screw fasteners?
Q235B and Q355B steels are recommended due to their high tensile strength and durability. These materials provide excellent load-bearing capacity and are compatible with hot-dip galvanizing for superior corrosion resistance.
How does hot-dip galvanizing protect solar fasteners?
Hot-dip galvanizing creates a thick zinc coating (≥85μm) that acts as a barrier against moisture and chemicals. This process extends the service life to over 3,000 hours in salt spray tests, making it ideal for coastal or industrial environments.
Can you customize nut and screw specifications for my project?
Yes, SJCT offers full OEM/ODM services. We can customize thread length, diameter, and coating thickness based on your engineering drawings and geological conditions, ensuring a perfect fit for your specific application.
What is the minimum order quantity (MOQ) for bulk purchases?
We accommodate large-scale orders with an annual capacity of 3 million pieces. While MOQ details vary by specification, our efficient production lines allow us to fulfill substantial volumes with competitive pricing and short lead times.
Do you provide after-sales support for international buyers?
Absolutely. We offer 24/7 English technical support, a 10-year warranty on main structures, and free replacement for confirmed manufacturing defects within 90 days. Our global logistics network ensures timely delivery worldwide.
