Import Carriage Bolts — Buy in Bulk from Supplier in China

Shanghai T & Y Hardware Industry supplies carriage bolts that meet multiple international standards, including DIN, ANSI, JIS and IFI, making them compatible with a broad range of fastening systems. The bolts are produced from carbon steel and alloy steel, providing a balance of strength and corrosion resistance, and they are finished with a protective coating to extend service life. The supplier lists ISO and SGS certifications for these bolts, indicating conformity with recognised quality management systems. The design incorporates a rounded head and a square neck to lock the bolt securely without rotation during installation.

Typical carbon‑steel carriage bolts of this class exhibit tensile strengths near 400 MPa, while alloy‑steel variants can reach higher values, which is common for demanding structural connections. A zinc or hot‑dip coating is standard for protecting against rust in outdoor or marine environments, and the rounded head distributes load evenly across the joint. The square neck aligns with a matching square‑socket nut, a feature widely adopted in construction, furniture manufacturing and general engineering for reliable, repeatable fastening.

The primary buyers are construction contractors, furniture factories and equipment manufacturers who require dependable, non‑rotating fasteners. Shanghai T & Y Hardware notes that minimum order quantities are adaptable, but the exact figure must be confirmed with the company. Prospective purchasers should request the specific ISO and SGS certificates, clarify the accepted incoterms and negotiate payment conditions before confirming any shipment.

Shanghai T & Y Hardware Industry Co., Ltd. operates from Rm. 509, Building 1, No. 388 Xinfu Road, Songjiang, Shanghai 201600, China. The company is classified as an imported‑tier supplier with a harbour trust tier, and its response metrics are currently listed as 0 percent, suggesting that buyers should verify communication responsiveness directly with the firm.

The catalogue states that the carriage bolts comply with DIN, ANSI, JIS and IFI standards and carry ISO and SGS certifications. No explicit details on MOQ, lead time or pricing are provided, so interested buyers need to request those specifics from the supplier before proceeding.
