采购者在采购镀锌马车螺栓之前应该了解什么
Carriage bolts have a smooth round head and a square neck under the head. The square neck helps stop rotation during tightening, especially in timber, slotted steel, brackets, and installations where the head side is not easy to hold. Buyers should confirm head diameter, square neck size, shank length, thread length, grade, finish, nut matching, and washer requirement before production.

材质及牌号说明
Carbon steel galvanized carriage bolts are commonly used for timber construction, equipment frames, agricultural hardware, guardrails, and outdoor brackets. Class 4.8 and 5.8 are often selected for general fastening, while Class 8.8 may be selected where higher strength is required. Stainless steel carriage bolts can be considered when the service environment requires corrosion resistance beyond galvanized carbon steel.
Grade, thread, and mating nut selection should be confirmed before bulk production. For nut and washer matching, buyers can review 如何将垫圈尺寸与螺栓和螺母尺寸相匹配 and the practical notes on 常见的螺栓、螺母和垫圈匹配错误.
表面处理选择指南
Zinc plating is often selected for clean appearance and moderate corrosion resistance in indoor or general outdoor applications. Hot dip galvanizing provides a thicker zinc layer for more exposed environments, but buyers should confirm coating thickness and thread fit. Mechanical galvanizing may be considered for certain assemblies where the process requirement is different from standard electroplating.
