Custom Dacromet Bolts Engineered for Extreme Corrosion and Heat Resistance - FastenMetal LTD

Fastenmetal Ltd was established in 2009, specializes in the development and production of Dacromet bolts. These bolts feature a high performance anti-corrosion coating made from zinc, aluminum, and chromate compounds, offering exceptional corrosion resistance (salt spray test exceeding 1200 hours), no risk of hydrogen embrittlement, and high temperature resistance (over 300°C). They are widely used in demanding outdoor environments such as power transmission, wind energy, automotive manufacturing, and bridge construction.

We provide fully customized dacromet bolts solutions based on client drawings, covering sizes from M6 to M30 and lengths from 100mm to 3000mm. Material options include carbon steel, stainless steel (304/316L), and corrosion resistant alloys.Finishes options include Dacromet coating, zinc plating, and more— to meet various application requirements.

All production processes strictly follow the ISO 9001 quality management system and JB/ZQ4321 national standards. Each product undergoes 18 quality control checks, including magnetic particle inspection and hardness testing, to ensure durability and reliability.

Yes

Fasteners & Stamping Parts Supplier

Fastenmetal is a experienced manufacturer produce fasteners and stamped metal parts. We specialize in OEM production based on customer drawings, offering both standard and custom made solutions.

Our fastener range includes car bolts, marine bolts, chemical bolts, stud bolts, threaded rods, and other high strength bolts.

1.Exotic Material Bolts

For bolts used in extreme environments such as marine, chemical, oil & gas, and aerospace industries,normally need higher corrosion resistance. FastenMetal supply custom bolts and metal components made from exotic materials such as Inconel, Monel, Titanium, and various types of duplex stainless steel.

2.High Strength Bolts

When regular bolts don’t meet strength requirements, we can produce bolts with strength grades up to Grade 12.9 for your requirements.

3.Custom Shapes and Sizes

We manufacture fasteners in special shapes, lengths, and diameters according to specific applications—fully customized according to your drawings.

In addition to fasteners, we offer custom stamping and metal fabrication services. We have 12 punching machines and press machines for large sheet metal forming and bending, we can handle part thicknesses up to 6mm.

In many of these cases, the customer’s engineering department will provide us CAD drawings and tell us the materials,strength grade they need. We produce samples for customers approval before bulk production.
