The precision of Haihao Group’s high-strength bolts and fasteners meets the demands of Malaysian customers
When a Malaysian client needed robust pipeline fasteners, Haihao Group delivered customized solutions that matched exacting standards. The order included high-strength bolts (HSFG), nuts, and washers designed for durability in demanding environments. Here’s how we ensured every component met—and exceeded—expectations.
Why Quality Matters for Malaysian Projects
Malaysia’s infrastructure projects require fasteners that resist corrosion and heavy loads. Our team supplied:
- Bolts: Sizes ranged from M16 to M24, with lengths tailored to the client’s specifications (e.g., Bolt M24 x 145 HSFG, Bolt M20 x 135).
- Nuts & Washers: Matched to each bolt size (e.g., M24 Hexagonal Nut, M20 Flat Steel Washer).
All items met BS EN ISO 898, BS 4190, or ASTM F3125M Grade A490M standards. This guarantees high tensile strength (Class 10.9) and hot-dip galvanized coating for rust prevention.

Customization That Fits Your Needs
No two projects are the same. We adjusted specifications to match the client’s requirements:
- Hot-Dip Galvanizing: Every bolt, nut, and washer received a zinc coating (ASTM F1136/F2833) for lasting corrosion resistance.
- HSFG Design: High-strength friction grip bolts ensure secure joints, even under vibration or extreme pressure.
For example, the Bolt M16 x 145 and Bolt M20 x 105 were crafted with precision to fit seamlessly into the client’s pipeline system.
Quality Control: Tested, Inspected, Approved
At Haihao Group, quality isn’t an option—it’s a promise. Every fastener underwent:
- Material Testing: Chemical and mechanical checks to confirm steel grade (A490M).
- Coating Inspection: Thickness and adhesion tests for galvanized layers.
- Dimensional Accuracy: Laser measurements to ensure perfect threading and fit.
This rigorous process eliminates defects and ensures compliance with both BS EN 14399 and ASTM rules.
