买家在采购DIN 603 马车螺栓之前应了解什么

DIN 603 carriage bolts have a round head, square neck, and metric thread. The round head gives a clean exposed side, while the square neck helps stop the bolt from rotating when the nut is tightened from the opposite side.

For export sourcing, the key is to define the installation condition. Wood, soft steel, slotted holes, and pre-punched square holes do not behave the same. Buyers should confirm head size, square neck dimensions, thread length, coating thickness, and whether bolts will be shipped alone or packed with matching 工业螺母 和 平垫圈.

制造和质量控制

Export supply of DIN 603 carriage bolts requires control over cold forming, square neck dimensions, thread rolling, heat treatment where needed, surface finishing, final inspection, and packing. A smooth round head and clean square neck are important for both appearance and installation.

Quality Control Points

1. Review DIN 603 size, material, grade, finish, nut and washer requirement, and packing method.
2. 需要时确认原材料等级和炉号可追溯性。
3. 检查圆头直径、头部高度、方颈宽度和方颈深度。
4. Check thread pitch, thread length, go/no-go gauge fit, and burr condition.
5. 根据适用的规定性能等级进行热处理。
6. Verify coating appearance, coverage, and thread function after surface treatment.
7. Pack by item code, size, grade, finish, and batch number for export receiving control.
