The type of bolt you use in a project depends on the materials and finish required for your application. For example, an outdoor construction project requires a hex head cap screw made from a corrosion-resistant material like stainless steel.
Button head socket cap screws have a low-profile design and can be used in applications where clearance is limited. They’re also rated for higher torque specifications than traditional hex head caps.
Material
Button head socket cap screws have a low, domed heads that provide more bearing surface area than conventional hex or Allen-drive screws. They’re ideal for use in tight spaces where a raised head could snag or interfere with moving machinery. These fasteners are fabricated from different grades of material, ranging from high-performance alloys to stainless steel. Each grade offers a distinct level of corrosion resistance, mechanical properties, and temperature tolerance.
Stocking distributor of button head socket caps, captive screws and flanged screws. Offers metric and inch sizes in alloy and stainless steel with zinc coating. Secondary services include kitting, packaging, sourcing and supply chain management solutions. Serves aerospace, construction, medical and automotive industries. CAD and SolidWorks files accepted for custom fasteners. Vendor managed inventory (VMI) programs and JIT delivery available.
Size
Button head socket cap screws have a low-profile socket that fits hex wrenches for turning. Their wide load-bearing surface resists loosening. This makes them suitable for applications with limited overhead or clearance.
Fastenright carries ISO 7380 Button Socket Head Cap Screws in property class 10.9 and A2 Stainless Steel. They have a wide, rounded head to resist cam-out and are easier to drive than other screw types.
Button head socket cap screws are often used in low-clearance applications that require a large area of clamping face. They also have a socket driver, which allows for more torque than hex or slotted drives and can help increase clamping force in thin materials. The socket driver is especially efficient when using power drivers. They can be driven into thin material that might not support a counter-sunk head, but they should still use a retaining washer.
Threads
Often referred to as dome screws, they are ideal for confined spaces and applications where a flush appearance is required. Their wide load-bearing face helps resist loosening. They also have a higher tensile strength than other screw types.
Button head socket cap screws are usually plated in CY-Chrome or CY-Onyx black chrome for a polished look that is resistant to corrosion and wear. These finishes enhance the aesthetics of an installation, which is important for visible applications.
The button-shaped head recessed into the socket drive provides a low profile for tight spaces and enables it to be driven with a hex wrench or allen key. These fasteners are able to withstand much higher torque specifications than slotted or cross-recessed drive machine screws. They can be used in most machining, die casting, and machine assembly applications. ISO 7380 button head socket cap screws host a hexagonal recess that is turned with a hex wrench or driver, making them more efficient than other drive types.
Finish
Button head cap screws have a deep hex recess and thick side walls, providing a robust and sturdy fastener. They are typically used when appearance is important, or where the clamping material is too thin to countersink. They can also be used in machine assemblies and tool and die applications.
The button-shaped head provides a stylish finish, free from sharp edges that could snag or catch on other equipment, making them ideal for safe and streamlined installations. Their versatility and durability make them a popular choice for many different industries, from furniture to automotive.
Selecting the right type of screw depends on the climate, environment, and load-bearing requirements for your application. Be sure to check the screw’s tensile and shear strength to ensure it can handle axial and lateral forces, respectively. Regular inspections can help detect signs of corrosion or other damage that could weaken the screw’s performance and cause mechanical failure. In addition, proper installation and maintenance techniques can prolong the screw’s lifespan and improve its reliability.button head bolt
