Fasteners used in construction must endure challenges like chemicals, weather, and temperature, impacting their strength, durability, and corrosion resistance. Materials and manufacturing methods influence their traits. Cold temperatures induce brittleness in fasteners, risking breakage. Austenitic stainless steel with high nickel and nitrogen content suits cold environments due to strength and reduced brittleness.

Hot, humid conditions alter fasteners' ductility and tensile strength, leading to creep and relaxation. To mitigate damage, use appropriate materials like steel, stainless steel, or medium carbon steel, avoiding those with iron and plastic components.

High temperatures temporarily reduce tensile strength and ductility in stainless steel fasteners, which often recover as temperatures normalize. Extreme heat can permanently damage fasteners, causing creep and relaxation – continuous deformation under stress and elastic-to-plastic transformation.

Creep involves constant high-stress-induced material deformation, while relaxation occurs as preload tension decreases post-tightening, causing elastic-to-plastic deformation in high heat.

In summary, temperature affects fasteners based on material and yield strength. Cold temps induce brittleness, while high temps can deform plastic elements. Understanding fastener traits aids in selecting the right ones for projects.
