What Are Hex Bolts?<\/strong><\/h2>\n

Hex bolts, also known as hexagon head bolts or hex cap screws, are fasteners with a six-sided hexagonal head designed for turning with a wrench . They feature machine threads for use with a nut or in a tapped hole, providing strong, secure connections between components . Hex bolts are available in fully threaded or partially threaded configurations, with the unthreaded shank portion offering additional shear strength.<\/p>\n
