OEM/ODM Brass Self Tapping Fasteners/Nuts/Screws Manufacturers

Brass Material Products – Precision Fasteners from a Dedicated Manufacturer

Zhejiang Donghe Machinery Technology Co., Ltd. is a high-tech enterprise and brass material products manufacturer based in Jiashan County, Zhejiang, China. We specialize in the development, manufacturing, and sales of fasteners and related components, with a production capacity of 8,000 tons per year. Our brass range covers screws, nuts, bolts, washers, bushings, and custom-machined parts, engineered for applications where corrosion resistance, electrical conductivity, and a clean appearance matter.

We supply OEM/ODM solutions to global customers in Europe, Australia, Africa, and the United States. Our factory operates over 100 sets of machines, supported by a dedicated mold workshop, cold heading lines, and an in-house laboratory. We produce to Chinese GB, German DIN, American ANSI, and British B standards, and we regularly manufacture non-standard fasteners from customer drawings or samples.

What We Offer in Brass

Our brass product line is built around the alloys that matter most in demanding environments. We stock and machine C36000 free-cutting brass, C46400 naval brass, C48500 high-leaded brass, and C27000 yellow brass. Each alloy is selected for its balance of strength, machinability, and corrosion resistance.

Product Range and Application Fit

We manufacture a broad range of brass fasteners, each designed for specific installation and service conditions. Our range includes:

• Brass screws – self-tapping, machine, and wood screw styles; available with cross, slotted, Torx, or hex drives.
• Brass nuts – hex, jam, wing, lock, cap, and slotted styles; metric and imperial threads.
• Brass bolts – hex head, socket cap, carriage; M3 to M64 or custom lengths.
• Brass washers and gaskets – flat, spring, and custom shapes for load distribution and sealing.
• Brass bushings and threaded inserts – for repair, reinforcement, or electrical termination.

These components are used in marine fittings, electrical switchgear, architectural railings, valve and pump assemblies, instrumentation, and hydraulic systems. The natural corrosion resistance of brass, combined with its non-sparking property, makes it a preferred choice for hazardous or saltwater environments.

Engineering and Customization

We understand that standard catalogs do not cover every project. Our engineering team works from drawings, samples, or even a simple description of the working point. We can adjust diameter, length, thread pitch, head style, and surface finish. For non-standard parts, we use cold heading, thread rolling, and CNC machining to produce prototypes and production runs.

Our in-house mold workshop allows us to control tooling quality and lead times. We also offer custom packaging and labeling to meet your logistics requirements.

Quality Assurance and Testing

We operate a laboratory equipped with optical sorting and inspection systems. Every batch is checked for dimensional accuracy, thread fit, and surface condition. Our quality management system is certified to ISO9001:2000, and we follow ASTM B16, DIN 934, ISO 4032, and SAE J995 where applicable. For brass components, we can perform salt spray testing to verify corrosion resistance, typically exceeding 500 hours per ASTM B117.

Information We Use to Configure Your Solution

To prepare an accurate quotation and production plan, we need the following details:

• Part drawing or sample, including dimensions and tolerances
• Required brass alloy (C36000, C46400, C48500, etc.)
• Thread standard (metric, UNC, UNF, BSW) and class
• Head style and drive type
• Surface finish (natural, polished, nickel, chrome, antiqued)
• Estimated annual quantity and delivery schedule
• Any special testing or certification requirements

Delivery and Support

We offer flexible order quantities, from prototype to high-volume production. Standard items may ship from stock; custom parts typically require 2–4 weeks depending on complexity. Our team provides technical support throughout the project, from material selection to installation advice. We export worldwide and handle all documentation for smooth customs clearance.

Frequently Asked Questions

What brass alloys do you recommend for marine applications?

For saltwater exposure, we recommend C46400 naval brass due to its excellent corrosion resistance. It is commonly used in boat fittings, dock hardware, and underwater sensors.

Can you produce brass fasteners with custom threads?

Yes, we can produce custom thread pitches and forms, including metric, UNC, UNF, and BSW. We also support non-standard thread classes and tolerances.

What is the minimum order quantity for custom brass parts?

Our minimum order is negotiable. For prototypes, we can accommodate small quantities; for production, we work with you to find an economical volume.

Do you provide test reports or certificates?

We can provide material certificates, dimensional inspection reports, and salt spray test results upon request. Our quality system is ISO9001 certified.

How do you ensure the quality of large orders?

We use optical sorting technology for 100% inspection of critical dimensions and surface defects. Our laboratory also performs random sampling for mechanical properties and corrosion resistance.
