Why are some fasteners preferred for high-strength requirements?

Fasteners that are preferred for high-strength requirements are primarily made of stronger materials. This aspect is critical because the strength of a fastener directly impacts its ability to hold components together under stress and load. For applications that require reliable and durable connections, such as in aerospace or heavy machinery, the material composition of fasteners plays a key role in ensuring they can handle high levels of tension and shear forces without failing.

Materials such as titanium, high-grade steel, or specialized alloys are often used for these types of fasteners due to their enhanced mechanical properties, including tensile strength, fatigue resistance, and durability. The selection of higher strength materials allows for smaller and lighter fasteners to be used without sacrificing performance, which is particularly advantageous in weight-sensitive applications, such as aircraft components.

While factors such as weight and temperature resistance may also be considerations in the selection of fasteners, the primary reason for their preference in high-strength applications is indeed their construction from stronger materials that ensure reliable and secure connections under demanding conditions.
