A button head bolt is a threaded fastener with a low domed or conical socket head that fits over a drive or hex key for turning. It is a great option for tight or confined spaces that need to be accessible with minimal overhead space. Its wide load bearing surface helps to distribute the force of the tightened screw. This bolt also provides a finished appearance that is popular for aesthetic applications.
Socket screws are high strength fasteners that are used in a variety of applications that require both shear and tensile strengths. They are often found in metal stamping dies, plastic injection molds, machinery, power transmission, hand and power tools, and more. All of our socket screws meet AISI, IFI, ANSI, and ASME standards and specifications.
Button head socket cap screws, or SBHCS as they are known in the US, feature a low domed or cone-shaped head with a drive hole to accept hex wrenches and insert bits. They provide a clean finish and can be driven with either an allen wrench or hex key. Our button head socket caps are produced in a wide range of materials, grades, and sizes.
Our socket cap screws are available in both black oxide and oil, mechanical zinc, and chrome finishes to withstand harsh environments and extreme temperatures. We carry standard inch sizes in property class 10.9, as well as metric sizes in A2 and A4 Stainless Steel.
