The Benefits of the Button Head Bolt
When you need to fasten something together firmly, bolts are the way to go. Various types of bolts are available to fit different applications, with some offering more strength than others. Among them, the button head bolt is an option that can be used in many applications. It has a rounded head and a flat bearing surface that makes it easy to grip with an Allen wrench or other tool. In addition, it has a larger area than standard socket head caps. This means it can withstand greater torques.
Aside from its large size, the button head bolt offers several other benefits. For one, it’s easier to drive than a screw or bolt with a round head, making it suitable for tight spaces that don’t allow you to reach the center of a hole. It also comes in a variety of finishes and materials to suit varying applications. You can choose from steel, alloy steel, and more exotic materials that offer different strength levels, corrosion resistance, and temperature tolerances.
While you might assume that head bolts are fairly rigid fasteners, the truth is that they’re designed to stretch when they’re tightened. This is because they must overcome a certain amount of give between the cylinder head and the block in order to keep everything tightly sealed. This is even more critical in engines with aluminum heads, which expand at twice the rate of cast iron. As a result, the head bolts can actually stretch up to 0.005 in diameter.
This stretching is necessary for proper operation of an engine, but it’s not the only reason for head bolts to be flexible. In an engine, the fasteners must withstand tremendous loads that can cause damage to the cylinder head and gasket. These loads can cause the cylinder head to crack and even separate from the block, resulting in poor cylinder sealing and lower power.
In an effort to prevent this from happening, engineers developed head bolts that are designed to stretch. This allows the fasteners to exert an equal amount of force against the cylinder head and gasket regardless of their torque reading. This eliminates variations in friction that would otherwise make some bolts tighter than others, improving cylinder sealability and ensuring that the gasket remains intact.
If you need a fastener that can withstand high amounts of pressure, the button head bolt is an excellent choice. Whether you need it for heavy-duty industrial projects or simple household tasks, this versatile bolt will help you get the job done quickly and effectively.
