ANSI/ASME B18.2.1 is the primary North American standard for imperial hex head bolts, governing dimensional tolerances, geometry, machining accuracy and technical requirements.
Our full-thread finished hex bolts are manufactured in strict accordance with this standard. Unlike partial-thread bolts, they feature continuous UNC/UNF imperial threads along the entire shank with no plain section. The precision-finished hex head ensures even torque distribution and non-slip wrench engagement.
With tight tolerances, superior surface finish and accurate thread form, these bolts offer full interchangeability with matching ANSI nuts and washers without reworking. They deliver reliable clamping force across varying workpiece thicknesses and perform better than commercial rough hex bolts.
Ideal for high-precision, stable and leak-tight connections in North American-spec machinery, steel structures and special equipment.
