ANSI/ASME B18.5 Round Head Square Neck Boltm custom hex bolts, auto parts
The ANSI/ASME B18.5 Round Head Square Neck Bolts from Zhejiang Zhongrui Auto Parts Co., Ltd. are specialized fasteners designed for applications requiring resistance to rotation, such as wood-to-metal or wood-to-wood joints. The square neck beneath the rounded head prevents the bolt from turning when tightened, ensuring stable connections in structural or heavy-duty assemblies. These bolts are manufactured from steel, adhering to the B18.5 standard for dimensional consistency.
The bolts feature a typical thread pitch of 1.0 - 1.5 mm for metric variants or 10 - 14 threads per inch for imperial sizes, with a standard thread tolerance of 6g for external threads. The round head provides a finished appearance, while the square neck, usually 1 - 2 mm larger than the shank diameter, locks into the material to prevent spinning. Surface finishes include plain, zinc-plated, or hot-dip galvanized, with zinc offering typical corrosion resistance of 200 hours in salt spray tests.
Primary buyers include construction firms, furniture manufacturers, and heavy machinery producers who require bolts that resist loosening under vibration or torque. These bolts are often used in timber framing, decking, and agricultural equipment, where their unique design eliminates the need for a separate washer or locking mechanism. Packaging and bulk terms should be confirmed with the supplier, as the listing does not specify MOQ or lead time.

Zhejiang Zhongrui Auto Parts Co., Ltd. operates from its facility in Jiaxing City, Zhejiang Province, at No. 680, Ya'ao Road, Daqiao Town, Nanhu District. The company is classified as an organic-tier supplier with a voyage trust tier, reflecting a verified but not highly detailed trade profile.

The company’s location in a major manufacturing region suggests access to raw materials and logistics infrastructure, but this should be validated for specific orders.

Sourcing ANSI/ASME B18.5 Round Head Square Neck Bolts from Zhejiang Zhongrui Auto Parts Co., Ltd. - China Import Guide
Before placing an order, confirm the bolt’s material grade and surface finish to ensure it meets your application’s environmental and load-bearing demands. Request material test reports or certifications to verify the steel’s composition and mechanical properties, as these are not provided in the listing.
Clarify logistics details such as packaging type (e.g., bulk boxes or cartons), lead time, and Incoterms (e.g., FOB Shanghai) directly with Zhejiang Zhongrui Auto Parts Co., Ltd. For large orders, discuss container loading plans and moisture protection for sea freight to prevent rust during transit.
Conduct a dimensional inspection on a sample batch, focusing on the round head’s diameter, square neck proportions, and thread pitch. Use a thread gauge to check pitch accuracy and a go/no-go plug gauge for thread tolerance. Document the supplier’s adherence to ANSI/ASME B18.5 and request third-party inspection for critical projects.
