The State of Israel represents a highly specialized industrial environment where civil construction, defense technology, and renewable energy sectors drive the consumption of high-strength fasteners. From the expansions of the Tel Aviv Metropolitan Area Light Rail Transit (LRT) to complex coastal defense structures along the Mediterranean, the mechanical requirements for structural nuts are unforgiving.
Operating in environments where marine salinity levels are high (such as coastal desalination facilities in Sorek, Ashdod, and Hadera) demands that fasteners exhibit extreme resistance to corrosion. Standard galvanized products often fall short of the required service life. As a result, industrial contractors increasingly demand advanced surface coatings like Geomet, hot-dip galvanizing with strict thickness controls, and specialized alloy steels.
Additionally, the rapid expansion of solar photovoltaic infrastructure across the Negev Desert introduces unique mechanical stresses. High thermal cycling between day and night causes constant expansion and contraction, making locking mechanisms and flange structural nuts critical to prevent vibration-induced loosening.
Our 30,000 sqm integrated facility operates at strict quality benchmarks, servicing construction networks worldwide.
Sinsun Hardware, established in 2006, has grown to become the largest self-tapping screw and structural nut manufacturing base in Northern China.

From Sinsun founding in 2006, Sinsun has grown into a leading Chinese fastener manufacturer. Explore our journey of expansion, from establishing exports in 2012 and integrating German technology in 2018, to achieving a 36,000-ton annual output and adding advanced heat treatment lines by 2025.
Sinsun began with a singular focus in 2006: to build a factory dedicated to self-tapping screws. This foundational specialization established our core expertise from the ground up. It remains the unwavering commitment behind every screw we manufacture today.
The year 2012 marked a pivotal step for Sinsun with the establishment of our Export Department. From that point forward, our specialized self-tapping screws began reaching customers across the world, expanding our mission beyond borders.
In 2015, Sinsun expanded its control over quality by adding four spheroidizing furnaces for raw material processing and in-house wire drawing capabilities. This strategic upgrade moved our production beyond screw manufacturing, beginning with precise control from the raw material stage. It ensures superior consistency and performance in every piece screw we produce.
Our production capability was enhanced in 2018 with new German multi-station cold heading machines. Concurrently, we grew our product line to include a variety of drill tail screws. This dual development strengthened our specialized manufacturing foundation.
Sinsun's growth in 2021 was defined by two key metrics: reaching 36,000 tons in annual production and fulfilling international orders with over 1,100 export containers. This period underscored our capacity to deliver at scale to a global market.
To ensure timely delivery for our clients, we operate a 1,200-square-meter ready-stock warehouse as of 2023. This facility is dedicated to supporting efficient daily distribution and meeting your routine supply needs.
The addition of four heat treatment lines in 2025 significantly boosts our production capacity. This directly translates to greater consistency in product quality and stronger guarantees for on-schedule delivery, meeting your project needs with confidence.
Discover how Sinsun Hardware regulates every step from alloy rod to high-strength nut.
At SINSUN, our quality control begins at the source. We start with premium raw materials from XING TAI Steel, then perform in-house spheroidizing annealing and precision wire drawing in our own plant. This end-to-end control, supported by our advanced drawing machines and gas-fired furnaces, ensures superior microstructure, consistency, and performance in every fastener we produce.
At SINSUN, we combine German-engineered multi-station cold heading machines with precision Taiwanese production technology. Our specialized processes, including tail-gripping for drill screws, ensure every fastener is manufactured with utmost accuracy and consistency in our state-of-the-art production facility.
SINSUN operates four dedicated heat treatment lines, allowing for precise and controlled processing time to achieve consistent hardness and enhanced product durability.
