Ningbo Songhe Fastener Co., Ltd. offers carriage bolts compliant with DIN603 and ISO8677 standards, covering a broad thread size range from M3 to M33 and 1/4 to 1 1/4 inch in UNC/UNF configurations. The bolts are available in multiple materials, including stainless steel (SUS304, SUS304L, SUS316, SUS316L) and carbon steel (1018A, 1022A, 35#, 45#, 35CrMo, 42CrMo, 40Cr), with grades such as A2-70, A4-80, 4.8, 8.8, and 10.9. Surface treatments include natural, passivated, black, zinc Cr+3, YZP, and hot-dip galvanized (H.D.G.).
DIN603 specifies a round head with a square neck under the head, designed to prevent rotation when installed in wood or soft materials. The thread length options (6 mm to 500 mm) and material diversity allow these bolts to serve applications from light-duty furniture to heavy industrial machinery. Stainless steel grades like A2-70 (SUS304) and A4-80 (SUS316) are typical for corrosion-resistant environments, while carbon steel grades (e.g., 8.8, 10.9) provide higher tensile strengths for structural use.
These bolts are widely used in European and international markets where DIN and ISO standards are preferred. Buyers in construction, shipbuilding, and automotive sectors often source DIN603 bolts for their precision and compatibility with metric nuts and threaded components. The supplier’s location in Dagang Industry, Ningbo, positions it near major ports for efficient bulk exports.

Before placing an order, confirm the exact material grade and surface treatment to ensure compatibility with your project’s environmental conditions and load requirements. For example, SUS316 (A4-80) is ideal for marine applications, while 10.9-grade carbon steel suits high-stress structural connections.
Discuss packaging and shipping terms with Ningbo Songhe Fastener Co., Ltd. to align with your logistics needs. Common Incoterms include FOB Ningbo or CIF to your destination port. Lead times may vary based on material availability, so request a production timeline for large or custom orders.
Quality control should include dimensional checks (e.g., head diameter, thread pitch, and neck square dimensions) and coating thickness measurements for plated or galvanized bolts. Request a third-party inspection certificate if your procurement policy requires independent verification. For stainless steel, perform a salt spray test (ASTM B117) to confirm corrosion resistance.
