Fastener
Aerospace Engineering · Mechanical Engineering · Last updated: July 30, 2026 · How this entry was written
Definition: A fastener is a hardware component used to mechanically join or affix two or more structural parts together, such as rivets, bolts, screws, or lockbolts. Fasteners in aerospace are designed to carry shear and tensile loads while resisting fatigue and corrosion.
Example in context
“The assembly manual specifies the use of Hi-Lok fasteners in the wing splice area due to their high shear strength and fatigue performance.”
“Montaj kılavuzu, yüksek kesme dayanımı ve yorulma performansı nedeniyle kanat birleşme bölgesinde Hi-Lok bağlantı elemanlarının kullanılmasını belirtir.”
Where engineers use it
Fasteners are critical in joining skin panels to stringers and frames. Engineers select fastener type and spacing based on load transfer requirements, fatigue life, and corrosion resistance, often using interference-fit fasteners.
Synonyms: mechanical fastener, joint hardware
In Mechanical Engineering
A hardware component, such as a bolt, screw, or rivet, used to join or secure two or more parts together.
“Every fastener on the flange joint was tightened to the specified torque and marked to confirm the inspection.”
Practice: can you use “Fastener” at work?
You are tasked with choosing a fastener for a high-stress area on an aircraft wing spar. Compare rivets, bolts, and lockbolts in terms of fatigue performance and installation constraints.
