Haihao Group Supplies Galvanized B7M Stud Bolts for an Iraq Project

Haihao Group has completed the supply of galvanized B7M stud bolts for a customer in Iraq. The order consists of 1/2-inch diameter stud bolts, 65 mm in length, supplied with two hexagonal nuts for flange and pressure equipment assembly.

The fastening set combines ASTM A193 Grade B7M stud bolts with ASTM A194 Grade 2HM nuts. The components are manufactured to the specified dimensional and material requirements, with the finished fasteners hot-dip galvanized to provide additional protection against corrosion during storage, transportation and service.

Order Details

The supplied fasteners are designed as a complete bolting set rather than loose individual components. Each set includes one stud bolt and two matching hexagonal nuts.

ASTM A193 B7M Stud Bolts for Pressure Applications

B7M stud bolts are commonly selected when bolting performance and material compatibility are important considerations in pressure-related equipment. ASTM A193 Grade B7M provides the specified material basis for the stud bolts in this Iraq order, while ASTM A194 Grade 2HM is used for the accompanying nuts.

Using the stud and nut materials specified by the project helps maintain consistency throughout the bolted connection. This is particularly important where flange connections need controlled assembly and reliable mechanical engagement.

For this order, the B7M stud bolts are supplied at 1/2-inch diameter and 65 mm length, giving the customer a compact bolting solution for the specified connection.

Hot-Dip Galvanized Finish

The fasteners are supplied with a hot-dip galvanized finish. Zinc coating provides a protective barrier between the steel surface and the surrounding environment, making galvanized fasteners suitable for applications where corrosion protection during handling, storage and service is required.

The coating also gives the finished B7M stud bolts a practical surface finish for industrial use while retaining the specified underlying steel grade.

Why the Nut Material Matters

A stud bolt assembly depends on both the stud and nut. The order therefore specifies ASTM A194 Grade 2HM for the two hexagonal nuts rather than treating the nuts as a generic accessory.

The matched set consists of:

• Stud bolt:ASTM A193 Grade B7M
• Nuts:2 × ASTM A194 Grade 2HM
• Size:1/2″ diameter × 65 mm long
• Thread:ASME B1.1
• Finish:Hot-dip galvanized

This specification-based approach reduces ambiguity during procurement and makes the delivered fasteners easier to identify during installation.

Haihao Group Fastener Supply

For this Iraq order, Haihao Group produced the stud bolt and nut assembly according to the customer’s specified material, dimensions and applicable standards. The focus was not simply on supplying standard hardware, but on providing a clearly defined bolting set with traceable specifications.

For customers sourcing B7M stud bolts, galvanized bolting sets or pressure-equipment fasteners, Haihao Group can support customized requirements covering dimensions, materials, thread specifications and surface treatment.
