When it comes to fastening products, there are a wide variety of screw types available. Each type has its own set of benefits and uses, but some are better suited for certain applications than others. One such screw is the button head cap screw, which is an ideal choice for tight spaces and other situations where a low-profile design is needed. Read on to learn more about this popular screw type and how it can benefit your next project.
The button head cap screw is a hex socket head screw with a rounded low-profile head that contains a hexagonal socket to fit a wrench for turning. It’s similar to a pan head screw, but it has a deeper socket and a higher tensile strength, making it a good option for tight spaces or heavy-duty applications.
These screws can be driven in and out of objects using a hex key, which makes them easy to use for many different projects. They are often used in tight spaces where it would be difficult or impossible to drive a standard screw, and they provide a stronger hold than regular socket cap screws.
Because of their wide load bearing surface, button head cap screws are also resistant to loosening, making them a good choice for applications that require a tight fit and a strong clamp. They are often used in industrial equipment, automotive applications, and other hardware and electronics. They are also useful for construction, including designing compartments in the overhead space of buildings.
Button head cap screws are available in a number of sizes and materials. Many are made of stainless steel, which offers high corrosion resistance and durability. This is a great option for many environments, especially those with humid or moist conditions. In addition, stainless steel has a high chromium content, which helps to prevent corrosion-related degradation.
Another common material for button head cap screws is black oxide, which provides a durable and attractive finish. This coating is typically applied to a steel or alloy base, and it’s often coated with zinc to protect against rust and corrosion. This is a popular option for many different types of fasteners, as it’s easy to apply and maintain.
You can also find black oxide and zinc button head cap screws that feature coarse thread, which provides a stronger hold than fine threads. Coarse thread also helps to prevent loosening over time, and it’s a great option for situations that may be subject to vibration or cyclic loading.
You can also find tamper-resistant versions of these screws, which are designed to resist attempts at removing or damaging the head. This type of screw is typically marked by a small collar around the bottom of the head that protects it from being unscrewed. The head of a tamper-resistant screw is also less rounded than a traditional socket head cap screw, which reduces the chance that it could snag on machinery or other objects in motion.
