Qiansheng Metal Manufacturing Co., Ltd. produces A325 / F3125 Grade A325 hex bolts with matching nuts and washers for steel construction and heavy-duty structural applications.
A structural connection depends on the complete assembly. Our bolts, nuts, and washers can be supplied as one coordinated solution, with components matched according to project requirements. Where specified, assemblies may include compatible nuts and washers such as A563 nuts and F436 hardened washers.
We review important details before quotation, including diameter, length, thread, material, finish, marking, quantity, packaging, and delivery requirements. Customers can send drawings, product specifications, or samples for evaluation.
A325 structural fasteners are commonly used in steel buildings, warehouses, industrial platforms, bridges, towers, and other demanding connection applications.
Qiansheng Metal Manufacturing will also attend the 140th Canton Fair in Guangzhou during Phase 1: Advanced Manufacturing, from October 15 to 19, 2026. International buyers are welcome to contact us before the fair to discuss A325 bolt assemblies and their sourcing requirements.
