Precision and Strength in One Fastener
A button head with flange pairs a rounded, low-snag head with a built-in bearing surface under the head, spreading load more evenly than a standard button head alone. The result is a clean finish, reduced need for separate washers in many applications, and smoother assembly on lines where speed and repeatability matter.
Our button head with flange offers a blend of form and function that makes it a reliable choice across various assemblies. Its low-profile, smooth head helps prevent snagging and protects finishes in tight or visible areas, ensuring a clean, professional look. The integrated flange distributes clamping force evenly, often eliminating the need for a separate washer in suitable applications.
If your design calls for the same clean profile without the flange, explore our Button Head Socket; if you prefer star-drive engagement for high cam-out resistance, check out our Button Head Torx.
Geometry and Standard
Drawing on BN 11252, our parts feature a button-shaped head with an internal hex drive and a collar beneath the head for added bearing surface. That combination gives you the compact look you want with the clamp stability you need.
Materials and Finishes
Choose from carbon steel, alloy steel, and stainless options with popular protective finishes to match your environment, appearance goals, and budget. Our stainless selections support corrosion resistance, while coated steel variants balance strength, value, and visual consistency.
Applications
Ideal for enclosures, brackets, guards, panels, furniture hardware, automotive trim, and any assembly where a smooth head and extra under-head support improve longevity and look. Designers use our button flange screws when visibility, safety, and repeatable torque control are top priorities.
FAQs
What does button head mean?
A button head is a rounded, low-profile screw head with a broad, smooth top that’s designed to minimize snagging and provide a clean, finished appearance.
What is the difference between a button head and a cap head?
A cap head (such as a socket head cap screw) has a taller, cylindrical head that accepts higher drive torque and often suits heavier clamp loads. A button head is lower profile for clearance and aesthetics; when combined with a flange, it gains a wider bearing surface for better load spread.
Are button head and pan head the same?
No. Both are low-profile, but a pan head typically uses a slot, Phillips, or similar drive and has a flatter top profile, while a button head is more rounded and commonly uses an internal hex or Torx. A button head with flange also adds an integrated collar for extra under-head support.
