Button Head Socket
Our button head socket gives you clean, low-profile strength without the bulk. If you want hardware that looks sharp, spreads load well, and installs fast with a hex key, our button head socket is the move. Built for builders who care about performance and finish, these are engineered to lock in tight and look great doing it.
Precision Design for Tight Spaces
Our button head socket features a shallow, dome-shaped head that sits close to the surface while offering a wider bearing area than standard socket caps, perfect when you need secure clamping without a tall head catching on gear or sleeves. The internal hex drive provides positive engagement for efficient torque and reduced cam-out, so installs are quick and controlled even in tight spaces.
The internal hex drive lets you work close to edges, recesses, and hard-to-reach spots with simple L-keys, T-handles, or power bits. The dome profile helps guide tools in quickly and reduces the chance of scuffing nearby surfaces. Pair them with washers when you’re clamping very soft substrates, or run them straight in where the head’s natural bearing area already gives you the coverage you want.
If your project calls for a similar profile with added holding area or a different drive style, consider our Button Head With Flange for extra load spread, or step into our Button Head Torx for high torque transfer and excellent tool life.
Why Choose Our Button Head Socket
Designed around ISO 7380 geometry, our screws deliver reliable fit and consistent head height across sizes for a professional look across your entire assembly. The rounded, low-rise head minimizes snags and gives panels, guards, and fixtures a smooth, finished appearance. That wider head surface distributes pressure more evenly than many small-head fasteners, helping protect softer materials and thin sheet from imprinting.
Materials, Finishes, and Sizes
We offer common metric sizes in carbon steel and stainless steel to suit your strength and corrosion-resistance needs, with popular finishes for added durability and aesthetics. Threads are cut to industry standards for dependable engagement, and the hex socket is precision-formed for repeatable tool fit. Whether you’re assembling machinery, outfitting equipment, or dialing in custom fabrications, you’ll find the length and diameter combinations you need for a tight, rattle-free build.
FAQs
When to use socket head vs button head?
Use a socket head cap screw when maximum clamping force and strength in a compact footprint are the top priority; the taller head accepts higher torque. Choose a button head when you want a low profile with a wider bearing surface and a smoother, snag-resistant finish. Many builders mix both in one assembly, socket heads for structural points, button heads for visible panels.
What are the advantages of button head screws?
They offer a sleek, low-profile head that reduces snags and looks clean on exposed surfaces. The larger bearing area helps distribute load on thin sheet or softer materials. The internal hex drive enables fast, reliable installation with common tools.
What is a button head fitting?
It’s an assembly point that uses a button head screw to fasten components where a low-rise, rounded head is preferred. The “fitting” typically includes the button head screw engaging a tapped hole or nut, sometimes with a washer to further spread load. You’ll see these fittings on covers, guards, brackets, and finished surfaces where both appearance and safety matter.
