When you're mid-project and need to adjust a jig, clamp a workpiece, or secure a panel without hunting for a wrench, a stripped hex bolt is the last thing you want. Woodworkers, machinists, and serious DIYers who rely on repeatable setups need fasteners that can be tightened and released by hand — quickly and reliably. These AN 265 butterfly wing screws are built for exactly that workflow.
Each piece is a single AN 265 thumb bolt with a wide, symmetrical wing head for secure hand-grip. Available in M10 and M12 thread diameters, with lengths ranging from 16mm (5/8") to 60mm (≈2-3/8"). Choose from 304 stainless steel, 201 stainless steel, or zinc-plated carbon steel. Order in packs of 1, 2, 3, 4, 5, or 10 pieces to match your project quantity.
Typical use cases include woodworking jig clamps and fence adjustments, machine guard panels requiring frequent removal, DIY furniture assembly with tool-free knock-down joints, and fixture plates on drill presses or router tables where quick repositioning is routine.

Each order contains the quantity of AN 265 butterfly wing screws you select at checkout — available in packs of 1, 2, 3, 4, 5, or 10 pieces. All pieces in a pack are the same size and material as chosen from the variant options above.
Match the thread diameter (M10 or M12) to your existing nut or threaded insert. For length, the grip length should generally equal the total thickness of the material being clamped, with at least 1.5× the thread diameter of thread engagement remaining. For example, M10 x 25mm (≈1") typically suits panels up to about 18–20mm thick. When in doubt, size up one increment.
AN 265 wing screws are designed for hand-tightening applications where tool-free adjustment is the priority. They are generally suitable for clamping, fixturing, and light-to-medium load fastening in woodworking and machine setups. For high-torque structural connections, a standard hex bolt is typically recommended instead.
304 stainless steel variants offer good corrosion resistance and are suitable for most outdoor and damp environments. 201 stainless steel provides moderate rust resistance, best for indoor or sheltered use. Zinc-plated variants are intended for dry indoor applications only and may show surface rust if exposed to moisture over time.
Yes. These wing screws use standard ISO metric coarse threads — M10 with a 1.5mm pitch and M12 with a 1.75mm pitch. They are compatible with standard metric hex nuts, T-nuts, threaded inserts, and tapped holes of the same size and pitch, which are widely used in woodworking jigs, machine fixtures, and general fabrication.
304 stainless steel contains a higher nickel content (typically around 8%), giving it superior corrosion resistance — the right choice for outdoor, marine-adjacent, or consistently humid environments. 201 stainless steel is a cost-effective alternative with moderate corrosion resistance, well-suited for indoor workshops or sheltered applications where occasional moisture exposure is possible but not constant.
No tools are required for standard hand-tightening. The wide AN 265 wing profile provides enough grip surface for firm tightening by hand in most clamping and fixturing scenarios. This makes them ideal for setups that require frequent adjustment or removal — such as adjustable stops, jig fences, or removable machine guards.
