Socket Button Head Machine Screws are a versatile fastening solution for a wide range of projects. They feature a rounded socket drive and can be tightened to higher torque specifications than slotted or cross recessed drive bolts and screws.
They also offer a more visually aesthetic appearance than standard socket cap screws. They are used in applications where a finished look is desired or when the clamping material is too thin to countersink the screw.
Threading Options
Unlike other screw types, the head of a button socket cap screw is domed rather than flat. This design reduces the likelihood that the screw will snag on tools and other equipment while being turned. It also provides a more finished appearance, making it a good choice for applications that require a visually appealing fastener.
These threaded bolts are available in a range of imperial and metric sizes. They are most often made from grade 10.9 steel, but they can be forged or machined from other materials such as brass and aluminium. They have a recessed hexagon drive and are driven with hex wrenches or Allen keys. They offer more resistance to cam-out than other drive types and can withstand high levels of torque specifications.
This makes them ideal for use in a wide range of industrial applications, including clamping, holding or attaching components together and in die castings. They are also commonly used in the automotive industry, in electrical applications, furniture assembly and DIY projects.
Material
Button head socket cap screws offer a low domed head with a wide bearing surface and a more finished appearance, making them ideal for use in applications where aesthetics are important. Their larger area driver allows for higher torque than traditional phillips or slotted drives, while their socket head design helps to distribute force more evenly.
They are typically tightened using an Allen wrench, providing greater efficiency and fewer loose fasteners. Their low profile also makes them less likely to snag or catch on moving machinery.

Button head socket cap screws have a lower, domed top that offers a finished appearance and helps reduce the risk of snags on moving machinery or in areas where the fastening point is exposed. They have a lower preload rating than traditional socket head caps. Low head socket cap screws have a head height 50% less than traditional socket caps and are ideal for tight spaces.
Applications
Generally, button head socket cap screws are used in light-duty fastening applications, but they’ve also found a home in construction where they’re popular for decorative elements and furniture pieces because of their sleek finish. They’re frequently employed in electronic devices to provide a smoother surface that helps prevent snagging of wires. They’re also integral to the automotive industry for aesthetically-driven components and in machinery because their rounded head profile lessens the chances of catching clothing or other objects on moving parts.
Button heads are designed with a hex socket drive hole to fit a wrench for turning and can be easily installed or removed using an Allen key. They’re usually rated for higher tensile loads than pan head or mushroom screws and can endure shear forces as well. However, their reliance on hex socket drives can result in stripped threads or cam-out if the wrong tool is used or a screw is over-torqued. It’s best to perform regular inspections and maintenance of these screws to ensure they hold up to a wide range of conditions.Button Head Bolt
