China All‑metal self‑locking nut Factory

What are blind rivets? Blind rivets are a type of single-sided rivet that requires a rivet gun (manual, electric, or automatic) for installation. These rivets are suitable for applications where standard rivets (which require riveting from both sides) are impractical, and are widely used in products such as construction, automotive, marine, aerospace, machinery, electrical appliances, and furniture.

When standard bolts are used for permanent connections, they must meet the following requirements: 1. For general bolted connections, flat washers should be placed under both the bolt head and the nut to increase the bearing surface area. 2. Flat washers should be placed on both the bolt head and the nut side. Generally, no more than two flat washers should be placed on the bolt head side, and no more than one flat washer should be placed on the nut side.

In the vast majority of ordinary mechanical equipment, protruding screw heads are common, but in high-end precision equipment, automated tooling, and precision molds, exposed screws are virtually nonexistent. This is not for aesthetic reasons, but rather a mandatory, unspoken standard in the precision industry. The core reason lies in the “hidden” assembly logic of set screws.

High-pressure and high-temperature flange connections for petrochemical, power and pressure vessel projects are prone to thread corrosion and galling, especially in Southeast Asia’s hot, humid and salt-spray intensive environments. Mismatched ordinary fasteners often cause thread seizing, medium leakage and non-detachable fixation, resulting in destructive disassembly, equipment downtime and high maintenance costs. Our standardized A193-B7 full-thread stud kits are fully matched with A194-2H heavy hex nuts and GB97 washers. The Vietnam exported M24×300 assembly features premium blue PTFE coating, reducing thread friction, preventing cold welding and boosting high-temperature and anti-corrosion performance. Fully compliant with ASTM standards and protected by professional thread sleeves for ocean shipping, the kits deliver stable preload and reusable disassembly for reliable flange operation.

The International Fastener Expo (IFE) will take place from October 7 to 9. As a core global trading platform for the fastener industry, it gathers procurement decision-makers from international engineering contractors and equipment manufacturers for face-to-face technical exchanges and supply-demand matching, enabling enterprises to explore new clients and keep up with trends of new materials and anti-corrosion technologies. Jiaxing Aoke Trading will present our full-range industrial fastener solutions at the expo. We support mixed bulk orders and custom non-standard fastener manufacturing, with supply options for special materials and fast responses to small-batch orders. Backed by a five-level full-chain quality control system, reliable surface treatment and 7×24 bilingual technical support, we deliver flexible cooperation solutions to resolve overseas procurement challenges. We sincerely look forward to in-depth on-site discussions with all partners.
