Button Head Bolt have a low, domed head and offer a finished appearance. They have a wide load-bearing surface that helps them resist loosening and can be driven with an Allen wrench (hex key).
They’re also great for applications where the bolts may come into contact with materials that could be damaged by a higher profile screw. They also provide more torque resistance than flathead bolts.
Material
The material used to manufacture Button Head Bolt contributes to its strength, durability, and performance. It’s crucial to consider the climate and environment in which the screw will be used, as well as any potential contaminants or corrosives it may come into contact with. You’ll also want to check its tensile and shear load capacities to ensure it can withstand the pressure it will be exposed to.
Metric button head socket cap screws are available in a range of materials, from black oxide and oil-based coatings to stainless steel and more. They also have a tamper-resistant hex drive, which makes them difficult to remove with regular tools. This feature is especially useful for security applications, as it prevents the head from being loosened accidentally. A low profile design also makes them an ideal choice for areas where a flush appearance is desired. They also offer a larger bearing surface than standard socket screws and can hold more tightening torque.
Threading
Stainless Steel Button Head Socket Cap Screws feature a load-bearing surface that resist loosening and a smooth, aesthetically pleasing appearance. They are often used in applications where the finish of the fastener is important or when a countersink is not feasible.
The internal hex socket allows for more torque to be applied than standard flat head cap screws. This provides more load-bearing surface area to resist loosening, and also allows for a tighter fit to the head of the bolt. This minimizes looseness and potential damage to the head.
Threads are commonly specified by the diameter and pitch in millimeters (e.g. M8x1.2). ISO metric screw thread preferred series has replaced many older systems including Whitworth and BA, but these are still in use. Alternatively, the thread may be identified by its letter code (e.g. UNC) followed by a number indicating its nominal thread width in decimal inches, or a multiplication factor (e.g., UNC 4-40).
Finish
The button head socket cap screw is a popular and reliable fastening solution for a variety of applications. Often used in automotive repairs, maintenance tasks, furniture assembly and heavy-duty industrial jobs that involve thick materials like steel alloys, these bolts can hold up to much more pressure than other types of screws.
They have a low profile head and recessed counter bore in the center that accepts a drive tool such as an Allen wrench. This design makes them ideal for a range of confined spaces that are hard to reach with larger tools.
They also have a wider loading surface than other types of bolts, which helps to distribute force more evenly. This can help to prevent damage to the material being fastened. As with all other types of bolts, it’s important to follow proper torque specifications during installation. This ensures that the screw will be able to resist loosening over time and won’t cause damage or breakage to the material being secured.
Design
Button head cap screws offer aesthetics and durability, making them a popular choice in many applications. They can withstand high levels of pressure and are resistant to loosening over time. They are also a good option for projects with limited space.
Stainless steel button heads offer corrosion resistance and can handle high temperatures. They can be fabricated from various types of stainless steel to meet specific application requirements. These include martensitic, austenitic, duplex, and ferritic. Each type of stainless steel offers different levels of strength and corrosion resistance.
For a more durable option, consider titanium button heads. These are strong and lightweight, yet still offer high corrosion resistance. They can be used in a variety of applications, from cycling rotor bolts to bottle cage mount bolts. They have a wide load-bearing surface that resists loosening and a flat head that provides a lower profile than hex socket screws. They can be driven with a standard wrench or driver and have a hex drive to prevent tampering.
