Butterfly Wing Nut DIN 315

The Butterfly Wing Nut DIN 315 supplied by Wanluo manufacturer is a specialized fastener specifically optimized for frequent adjustments, quick disassembly and assembly, and manual manual tightening scenarios under the German standard system. It is fundamentally different from conventional hexagonal nuts and self-locking nuts, which require a wrench or socket for installation. This product adopts an integrated double-wing symmetrical butterfly structure, and can complete locking and disassembly solely through manual operation. No professional tools are needed for assistance, significantly simplifying the equipment debugging and maintenance process.

The Butterfly Wing Nut DIN 315 produced by Wanluo Factory is particularly suitable for use in spaces with limited dimensions, high-frequency adjustment points, and equipment structures that require frequent disassembly and maintenance. It solves the practical construction problems of traditional fasteners, such as cumbersome operation, low debugging efficiency, and the inability of tools to function.


Details

The entire product is manufactured using a single-piece forging process, combined with ergonomic arc-shaped bending wing plates. The edges are smooth and free of burrs, providing sufficient contact surface for hand-held application. It has a comfortable grip and easy force application. The overall rigidity of the body is sufficient. Under normal human force application, there will be no bending, breaking, or deformation of the wing plates. The internal threads are processed using a precise high-speed tapping process, with standard pitch and smooth engagement. The insertion process is smooth without any jamming or slippage, and the locking is precise and stable. It is paired with high-quality stainless steel substrate, which combines structural toughness and corrosion resistance. It can withstand frequent repeated disassembly and is suitable for long-term use in harsh conditions such as open-air and humid environments. The fastening performance is durable and stable, and the appearance is not prone to rusting or discoloration.


User's genuine evaluation

Equipment debugging manufacturer's procurement

In our workshop, many test equipment and adjustable brackets require frequent fine-tuning of tightness. Previously, using ordinary nuts required a wrench and was difficult to operate in narrow corners. After replacing with this Butterfly Wing Nut DIN 315, it can be fully tightened by hand, significantly improving the debugging efficiency. The nut's wing is thick, and even when tightened hard, it won't deform. The thread engagement is very tight, and after being disassembled and reassembled dozens of times, it remains smooth without any slippage. The quality is very stable.

Outdoor mechanical modification merchants

Mainly used for fixing outdoor lightweight equipment brackets. In open-air environments, exposed to wind and sun, ordinary iron nuts are prone to rust and become stuck. This stainless steel material has excellent anti-rust effects, and the surface remains clean even after long-term outdoor placement, without the problem of rust and difficulty in disassembly. No tools are needed for manual disassembly and assembly, making maintenance and equipment inspection very convenient. It is highly suitable for outdoor equipment structures that require frequent maintenance.

Workshop fixture processing factory

Bulk purchase for workpiece positioning and auxiliary pressing structures, with high requirements for nut precision and stability. This nut has a standard tooth shape and has a high compatibility with standard bolts, fitting tightly after tightening without loosening. The integrated forging structure uses very solid materials, without the problem of thin materials becoming soft. Manual force locking does not cause edge cracking or deformation, and the batch assembly consistency is very good. The failure rate is extremely low after long-term batch use.

Cross-border hardware trader

Produced strictly in accordance with German standards, with standard specifications and strong versatility. It is easy for overseas customers to adapt. The workmanship is fine, with well-polished edges and corners without burrs, and the overall appearance is exquisite and substantial. It focuses on the advantage of no-tool disassembly, suitable for various adjustable equipment, furniture hardware, and lightweight mechanical assembly. The target scenarios are wide, and the customer's repeat purchase rate is very high.


Structural Ergonomics & Operational Advantages

Butterfly Wing Nut DIN 315 feature ergonomic double-wing bending design with smooth rounded edges, providing large friction contact area for handheld operation. The integral one-piece forging structure ensures high overall rigidity, avoiding wing deformation or breakage during manual force application. Precision internal thread tapping delivers standard tooth pitch and smooth screwing experience, ensuring accurate locking and no thread jamming. Made of high-quality stainless steel material, the product integrates excellent structural toughness and corrosion resistance, adapting to repeated frequent disassembly and long-term open-air use, maintaining stable fastening performance and neat appearance.

FAQ

Q1: What is the biggest advantage of Butterfly Wing Nut DIN 315 over ordinary hex nuts?

A1: Wing nuts support complete tool-free manual operation, suitable for frequent adjustment and rapid disassembly scenarios. Ordinary hex nuts require professional tools for locking, which is inefficient for daily debugging and maintenance work.


Q2: Are stainless steel wing nuts easy to break during manual tightening?

A2: Adopting integral forging and thickened wing structure, our wing nuts have strong toughness and bearing capacity. Under normal manual force range, no fracture or deformation will occur, ensuring long-term stable use.


Q3: Can wing nuts be used for high-load heavy fastening?

A3: Wing nuts are mainly designed for adjustable, low-load and frequent debugging scenarios. For heavy-load and high-vibration equipment fastening, it is recommended to match standard lock nuts or flange nuts for auxiliary reinforcement.


Q4: Do you support customized oversized or thickened wing nuts?

A4: Yes. We support personalized customization of wing width, thickness, nut body height and thread specifications to meet special adjustment space and operation requirements of non-standard equipment.


Q5: Are DIN 315 wing nuts interchangeable with standard metric bolts?

A5: All products adopt unified metric standard thread tolerance, which can be perfectly matched with our full series of metric bolts, threaded rods and studs with high versatility.
