Stainless Steel Butterfly Screw
Specification
Stainless Steel Butterfly Screws | Metric and Imperial Sizes
Stainless steel butterfly screws, also known as wing screws, feature a two-winged head that allows users to tighten or loosen the screw by hand without the need for a screwdriver. They are ideal for applications that require frequent adjustment, quick assembly and disassembly, or regular maintenance.
Our available sizes cover metric threads from M3 to M10 and imperial sizes from 5/32" to 3/8", with a variety of lengths available for different equipment clearances, clamping thicknesses, and mating components. Before ordering, it is important to confirm the thread system, thread diameter, thread pitch, stainless steel grade, and length measurement method to ensure compatibility with existing nuts or threaded holes.
Stainless Steel Butterfly Screw Features
- Two-winged head: Provides a convenient gripping surface for hand tightening and loosening, making these screws suitable for components that require frequent adjustment, removal, or maintenance.
- Metric and imperial sizes: Available in both metric and imperial thread systems to match existing drawings, nuts, threaded holes, and other components.
- Multiple lengths: Different screw lengths are available to accommodate various clamping thicknesses, engagement depths, and installation spaces.
- Stainless steel construction: The appropriate stainless steel grade and surface condition should be confirmed according to the intended application and operating environment.
- Easy hand operation: The wing-shaped head provides a direct gripping point, making the screws convenient for applications where using a conventional screwdriver is impractical.
Common Applications
Stainless steel butterfly screws can be used in a wide range of applications, including:
- Machine guards and inspection panels
- Equipment housings and removable covers
- Jigs, fixtures, and positioning structures
- Display racks, brackets, and merchandising equipment
- Assemblies that require hand tightening or adjustment
- Components that require regular disassembly, cleaning, or maintenance
For applications involving vibration, outdoor exposure, moisture, chemicals, or specific load requirements, please provide details of the operating environment and mating components. This information helps determine the appropriate stainless steel grade, thread pitch, and dimensions.

What Specifications Should You Confirm Before Ordering?
Thread System, Diameter, and Pitch
Confirm whether a metric or imperial thread is required, and provide the thread diameter and pitch. Selecting a screw based only on its approximate outside diameter or appearance may result in incompatibility or thread damage.
Screw Length
Please specify the required screw length and the measurement reference point, as well as the required thread engagement depth. If the required dimensions are difficult to determine, you can provide a part drawing, assembly drawing, or physical sample for reference.
Stainless Steel Grade
If a specific stainless steel grade is required by the engineering drawing or end market, please specify it directly. If the grade has not yet been determined, please provide information about indoor or outdoor use, moisture, temperature, chemical exposure, and cleaning conditions so the material requirements can be evaluated.
Mating Components
Please provide the dimensions and specifications of the mating nut, threaded hole, or assembly component. Also indicate whether washers, stops, locking features, or other anti-loosening measures are required.
Packaging and Documentation
For overseas orders, please specify the required packaging quantity, label information, barcodes, carton markings, delivery destination, and any required inspection reports or material documentation.

The more complete the specifications, the more efficiently we can confirm the required product and quotation conditions.
Frequently Asked Questions
What applications are butterfly screws suitable for?
Butterfly screws are suitable for applications that require hand adjustment, regular maintenance, or repeated assembly and disassembly. For structures subject to vibration or specific loads, the buyer's engineering team should evaluate the appropriate fastening method based on the actual application and design requirements.
How do I choose between metric and imperial butterfly screws?
The correct thread system should be determined based on the existing engineering drawing, nut, or threaded hole. Check the thread system, diameter, and pitch before ordering. Metric and imperial threads should not be substituted for one another based solely on similar outside diameters.
Do I need to specify the stainless steel grade when requesting a quotation?
If the engineering drawing or end-use market specifies a material grade, please provide the required grade. If no grade has been specified, provide details about the operating environment, temperature, moisture, chemical exposure, and cleaning conditions so the material requirements can be evaluated.
Can I request a quotation using only a photo?
A photo can be useful for preliminary identification, but we recommend also providing the thread diameter, thread pitch, length, material, and required quantity. An engineering drawing or physical sample can further reduce the risk of dimensional errors.
What delivery information should overseas buyers provide when requesting a quotation?
Please provide the destination country, delivery location, estimated quantity, packaging requirements, label language, and required documentation. This information helps us determine the appropriate quotation scope and shipping requirements.
