What type of fastener is commonly used for applications requiring high tensile strength?

Bolts are commonly used for applications requiring high tensile strength due to their design and the materials typically used in their manufacturing. They are specifically engineered to create strong, secure joints between various components, making them ideal for structural applications where loads and forces can be significant.

Bolts are designed to be used with nuts or in pre-tapped holes, allowing for high clamping force when torqued, which enhances their ability to withstand pulling forces without deforming or failing. This makes them reliable choices in heavy-duty applications, such as construction and machinery assembly.

In contrast, wood screws, machine screws, and sheet metal screws are generally used for lighter applications or specific materials and may not offer the same level of tensile strength as bolts. Wood screws are designed for fastening wood, and while they can provide good hold in softer materials, they lack the tensile strength needed for heavier applications. Machine screws provide secure fastening as well, but they are typically used in scenarios where the fastening cannot be removed frequently. Sheet metal screws are designed for fastening thin materials together and are not intended to withstand significant tensile loads. Therefore, bolts are the preferred choice for high tensile strength requirements.
