RC028-6 Black Hex Bolts are aftermarket hex-head fasteners sized 1/2 in. in diameter, with a 3/8-24 thread and 2 in. overall length, manufactured to Grade 5 and finished in black. This listing shows a 34-piece lot of New Old Stock (NOS), offering unused bolts for replacement or project work. For those new to bolt specifications: 1/2 in. refers to the nominal shank diameter, 3/8-24 indicates the thread pitch, and 2 in. is the length from under the head to the end of the bolt. The RC028-6 designation identifies this exact bolt configuration, helping ensure a precise fit in compatible assemblies. The black finish provides a visual match with darker hardware and assemblies where color coordination matters.
