ISO 8678 Stainless Steel Carriage Bolts, also known as round head low square neck bolt, is a fastener. ISO 8678 Stainless Steel Carriage Bolts is a bolt manufactured in accordance with ISO 8678 standard, with a round head shape and a square neck design. According to ISO 8678 standard, the specification size of round head square neck carriage bolt may include different diameters (d) and lengths (L). For example, in some versions, the diameter range (d) may be M6 to M16, and the length range (L) may be 30 to 160 mm. The round head design makes the protrusion height of the bolt head on the surface of the connection smaller, which is suitable for occasions where surface flatness is required. The square neck design makes the bolt stuck in the groove during installation, which helps to prevent the bolt from rotating when tightening, and can move parallel in the groove, providing a certain adjustment space. It is suitable for places where the force is not large, so the material is usually softer.
