Handan Daoning Fasteners Co., Ltd. supplies ASME B18.2.1 square head bolts in sizes ranging from 1/4 inch to 1 1/2 inch (M6 to M38 in metric), manufactured from carbon steel, alloy steel, stainless steel, or brass. The bolts conform to grade specifications such as SAE J429 Gr. 2, 5, 8, ASTM A307 Gr. A, and metric classes 4.8, 5.8, 6.8, 8.8, 10.9, and 12.9, offering a broad selection for mechanical and structural applications. Thread types include coarse (UNC), fine (UNF), and metric (M), with finishes like plain, zinc plated, black oxide, nickel, chrome, or hot-dip galvanised.
Square head bolts are designed for applications requiring high torque resistance and a positive drive, such as in heavy machinery, construction, and automotive assemblies. The square head provides a larger bearing surface than hexagonal heads, reducing the risk of bolt head deformation under high loads. Material selection depends on the environment: carbon steel for general use, alloy steel for high strength, stainless steel for corrosion resistance, and brass for electrical or non-magnetic applications.
These bolts are packaged in bulk cartons with a maximum weight of 25 kg per box, plus wooden pallets for larger shipments. Handan Daoning Fasteners Co., Ltd. offers a supply capacity of 1000 tons per month, with a minimum order quantity of 500 kg per specification. The company supports global markets, including North and South America, Europe, and Asia, and provides trade terms such as FOB, CIF, CFR, CNF, EXW, DDU, and DDP.

Before ordering ASME B18.2.1 square head bolts from Handan Daoning Fasteners Co., Ltd., confirm the exact grade, material, and finish required for your application. Request samples for testing, especially if the bolts will be used in high-stress or corrosive environments. Verify that the thread type (UNC, UNF, or metric) matches your assembly requirements to avoid compatibility issues.
Logistics for these bolts typically involve sea or air freight, depending on urgency and volume. Clarify the incoterms (e.g., FOB, CIF) to determine responsibility for shipping, insurance, and customs duties. For large orders, discuss palletisation and container loading to optimise space and reduce costs. Payment terms such as TT or LC should be agreed upon in advance, with clear conditions for deposits and final payments.
Quality assurance is essential for fasteners used in critical applications. Request material test reports (MTRs) for each batch to confirm compliance with the specified grade and mechanical properties. For added certainty, arrange for third-party inspections or testing, such as tensile strength, hardness, and corrosion resistance. Ensure all bolts are properly labelled with batch numbers and certifications for traceability during and after shipment.
