Button Head Bolt

Button Head Bolt are threaded fasteners that have a raised dome-like head and a hexagonal drive hole used for turning with an Allen wrench (hex key). These screws feature a smooth surface and clean head for a visually aesthetic appearance.

They are available in a variety of lengths and materials to meet various application requirements. Typically, they are made of 304 or 316 stainless steel or black oxide 18-8 steel to provide corrosion resistance, strength, and durability. However, some bolts are also made from more exotic and hardwearing metals like Inconel or Monel to support high-pressure applications.

These fasteners are most commonly used in machinery, electrical equipment and manufacturing because of their versatility and functionality. They are able to withstand high loads and can be installed in tight spaces due to their wide load bearing surface. They have a high tensile strength which allows them to withstand axial force, and their shear strength is good enough to resist breaking under lateral forces.

Despite their high tensile and shear strengths, these fasteners are susceptible to loosening if they are not installed properly or regularly inspected and maintained. Some of the most common causes include improper installation, poor quality tools, and over-tightening. This can cause the screw to break or deform and may lead to mechanical failure.

To reduce the chances of loosening, it is recommended that these screws be installed using a torque control tool and that they are stored in an environment suitable for their material type. Regular inspections will help to identify signs of wear and damage early on. In addition, the correct tools should be used during installation and removal to ensure that the bolt is not damaged.
