DIN 603 Schlossschrauben Exporteur
XZ Fastener supplies DIN 603 carriage bolts for overseas distributors, construction hardware buyers, OEM factories, and project procurement teams. DIN 603 is a metric round head square neck bolt designed for smooth exposed fastening and anti-rotation support during nut tightening. Export orders can be supplied according to buyer requirements for size, thread length, strength class, material, surface finish, nut and washer matching, carton labeling, pallet packing, and inspection documents.
Kurzspezifikationen
Was Käufer vor der Beschaffung von Schlossschrauben DIN 603 wissen sollten
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 Industrienüsse und flache Unterlegscheiben.

Material- und Sortenerklärung
Class 4.6 and 4.8 carbon steel carriage bolts are common for general hardware, fencing, timber structures, and construction use. They are suitable where the joint does not require high tensile strength.
Class 8.8 is selected for stronger assemblies, but the connected material and mating nut must be reviewed. Stainless A2-70 and A4-70 are used where corrosion resistance is more important than carbon steel strength.
If an export shipment includes DIN 933 full thread hex bolts, Grade 8.8 carbon steel hex bolts, or metric hex head bolts, keep item codes and carton labels separate from DIN 603 carriage bolts to reduce receiving errors.
Leitfaden zur Auswahl der Oberflächenbeschaffenheit
| Fertig | Export Use |
|---|---|
| verzinkt | Common for general indoor hardware, brackets, and distributor stock. |
| schwarz oxidiert | Used for machinery or appearance-focused applications with light protection. |
| feuerverzinkt | Wird für Außenzäune, Leitplanken, Holzkonstruktionen und freiliegende Baubeschläge verwendet. |
| Zinkflocken | Suitable where improved corrosion resistance and controlled coating thickness are specified. |
| Passivierter Edelstahl | Used for stainless carriage bolts in wet, outdoor, or mildly corrosive conditions. |
For broader coating choices, see XZ Fastener’s Beschichtete Verbindungselemente. Buyers ordering zinc plated DIN 933 bolts, black oxide DIN 933 bolts, and hot dip galvanized DIN 933 bolts in the same shipment should separate finish codes clearly on the purchase order.
Herstellung und Qualitätskontrolle
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
- Review DIN 603 size, material, grade, finish, nut and washer requirement, and packing method.
- Bestätigen Sie bei Bedarf die Rückverfolgbarkeit von Rohstoffqualität und Chargennummer.
- Überprüfen Sie den runden Kopfdurchmesser, die Kopfhöhe, die Breite des quadratischen Halses und die Tiefe des quadratischen Halses.
- Check thread pitch, thread length, go/no-go gauge fit, and burr condition.
- Gegebenenfalls eine Wärmebehandlung gemäß der angegebenen Festigkeitsklasse durchführen.
- Verify coating appearance, coverage, and thread function after surface treatment.
- Verpacken Sie nach Artikelcode, Größe, Qualität, Ausführung und Chargennummer für die Exporteingangskontrolle.

FAQ
Was ist ein DIN 603 Schlossschraube?
It is a metric round head square neck bolt. The smooth round head is exposed on one side, while the square neck helps prevent rotation during nut tightening.
Can DIN 603 carriage bolts be exported with nuts and washers?
Ja. Sie können je nach Bestellanforderung nur als Schrauben oder als Satz mit kompatiblen Muttern und Unterlegscheiben geliefert werden.
Which finish is suitable for outdoor export orders?
Hot dip galvanized and some zinc flake finishes are commonly selected for outdoor exposure. The final choice depends on corrosion conditions, assembly fit, and buyer specification.
Welche Qualitäten werden üblicherweise geliefert?
Class 4.6 and 4.8 are common for general hardware and construction use. Class 8.8 can be supplied for stronger assemblies. Stainless A2-70 and A4-70 are used for corrosion resistance.
Why should buyers confirm the square neck size?
The square neck must seat into the mating material or hole correctly. If it is too loose, the bolt may rotate. If it is too large, installation can damage the connected part.
