A threaded fastener component designed to secure machine parts through axial tension and shear resistance.
A fastener body or bolt is a cylindrical mechanical component with external threading, typically featuring a head at one end for torque application. It functions by creating clamping force through tension when tightened with a nut or into a tapped hole, providing secure joint connections in machinery assemblies. Bolts are engineered to withstand axial loads, shear forces, and vibration while maintaining structural integrity.

Bolts typically require nuts for assembly and are designed for through-holes, while screws engage directly with tapped holes. Bolts generally have unthreaded shank sections for shear resistance.
Select based on required tensile strength, shear capacity, and environmental conditions. Grade 8.8 is common for general machinery, while 10.9/12.9 grades are for high-stress applications. Consider corrosion requirements for material selection.
Vibration, thermal cycling, insufficient preload, improper torque application, or joint relaxation. Use locking mechanisms like nylon inserts, thread lockers, or prevailing torque nuts for critical applications.
