Industrial Innovation: The Stainless Steel Wing Nut Screw Assembly
The Stainless Steel Wing Nut Screw, also recognized as the Butterfly Nut Bolt Set, is a premier fastening solution where manual adjustability and rapid maintenance are required. Unlike conventional hex bolts that necessitate a wrench, our Wing Nut Fasteners are designed with ergonomic “wings” that allow for high-torque hand tightening. As a leading Fastener Manufacturer, Youjia Metals produces these assemblies with a focus on thread smoothness and material purity, ensuring that every SS304 Wing Nut Screw provides a vibration-resistant bond in lightweight and medium-duty industrial applications.
The engineering value of our Wing Nut and Screw Kits is derived from the precision alignment of the Pan Head Machine Screw and the Butterfly Nut. In sectors such as consumer electronics, medical equipment, and temporary structural displays, the requirement for a fastener that can be serviced without external tools is critical. Our Stainless Steel Screws are cold-forged and then thread-rolled to hit Tight Tolerance specifications (Class 6g/6H). This specialized thread rolling work-hardens the surface, preventing the dreaded Stainless Steel Galling—a cold-welding phenomenon often encountered during repeated manual assembly of lower-grade hardware.
Sourcing Wholesale Wing Nut Screws from an ISO 9001 factory like Youjia Metals provides B2B clients with uncompromised quality assurance. We utilize high-purity austenitic Stainless Steel to guarantee that the protective chromium oxide layer is uniform across the entire assembly. For procurement managers, this translates to a Concrete Fastener-like stability in non-masonry substrates, with 100% material traceability (MTR). Whether you are securing drum hardware or industrial access panels, our Butterfly Nut Fasteners offer the perfect synergy of speed and strength.

Precision Fabrication & Advanced Metallurgy
Manufacturing a reliable Stainless Steel Wing Nut Screw requires careful attention to the crystallization of the metal during the forming process. At Youjia Metals, we utilize multi-station cold-heading machines to form the Phillips Pan Head. This process aligns the grain flow with the head’s geometry, providing 20% higher Tensile Strength compared to CNC-turned screws. Following the heading process, threads are formed via precision rolling dies, ensuring that the Butterfly Nut Bolt assembly features a glass-smooth interface for reliable, repeatable manual operation.
The Wing Nut itself is often produced through precision investment casting or cold stamping, depending on the required wing geometry. After manufacturing, each Stainless Steel Fastener assembly undergoes electropolishing to remove microscopic surface imperfections where corrosion could initiate. Our ISO 9001 quality control protocols involve batch-testing for breaking torque and destructive tensile testing. For our global B2B supply chain partners, we provide full Material Test Reports (MTR), ensuring that your Industrial Hardware complies with all safety and engineering requirements.

Technical FAQ
A: Purchasing the Stainless Steel Wing Nut Screw Assembly as a complete kit ensures 100% thread compatibility and reduces labor costs for your assembly team. It also guarantees that the washer and nut match the screw’s Material Grade and Tensile Strength perfectly.
A: While hand-tightening provides excellent torque, for high-vibration applications, we recommend adding a spring washer or a drop of thread-locking compound. As an OEM Fastener Manufacturer, we can also supply Wing Nuts with nylon inserts for added security.
A: Yes. We provide extensive Custom Stamping and machining services. Whether you require M3 or M12 diameters, our facility can manufacture bespoke lengths up to 200mm based on your technical CAD drawings or samples.
