Manufactured by Ningbo Yongbiao International Business Co., Ltd in Zhejiang, China, they are available in grades B7, B7M, B8, B8M and B16, meeting the ASTM A193 specification for high-temperature and high-pressure environments. The bolts are produced from stainless steel (304/316) or carbon alloy steel, with finishes including black, zinc, HDG, PTFE, YZN and plain.
The material selection for each grade aligns with industry standards: B7 and B7M are carbon alloy steel with a typical tensile strength of 105 ksi (724 MPa), while B8 and B8M are 304/316 stainless steel with a typical tensile strength of 75 ksi (517 MPa). B16 grade uses chromium-molybdenum steel for elevated temperature service. Thread sizes range from 1/2"-13 to 4"-8, with lengths up to 50 inches, and are manufactured to ASME B1.1 or ISO 724 thread standards typical for industrial fasteners.
These stud bolts are exported globally for use in flanges, valves and pressure vessels where reliable performance under extreme conditions is non-negotiable. The supplier offers free samples for stocked sizes and custom packaging options, including carton sizes of 36x24x16 cm or 36x24x12 cm and standard Euro pallets (110x80x90 cm). Lead times are typically 7 to 15 working days, depending on order quantity, with shipments dispatched from Ningbo port.

Before ordering, confirm the exact grade and material composition of the stud bolts, as these determine their suitability for high-temperature, high-pressure or corrosive environments. Request Material Test Reports (MTRs) to verify compliance with ASTM A193 specifications, including chemical analysis and mechanical properties. Ensure the supplier can provide certifications for the heat treatment and testing processes used, as these are critical for traceability.
Clarify packaging and labeling requirements to match your inventory and handling systems, and confirm whether the supplier can accommodate custom marking (e.g., grade, lot number, or heat code) on the bolts. Discuss Incoterms such as FOB Ningbo or CIF to your destination port, and agree on payment terms like T/T 30% deposit with 70% balance before shipment. Lead times should be confirmed in writing, with provisions for expedited shipping if project deadlines are tight.
Upon receipt, conduct dimensional inspections to verify thread pitch, diameter and length against the purchase order specifications. Use a thread gauge to check compliance with ASME B1.1 or ISO 724 standards, and perform a visual inspection for surface defects or coating inconsistencies. For critical applications, consider third-party inspection or witness testing to validate the bolts’ mechanical properties before installation.
