Heavy Duty 304 Stainless Steel Countersunk Washers for Surface Protection

304 Stainless Steel Cup Washers: Metric & Inch Sizes for Countersunk Screws

Our 304 Stainless Steel Cup Washers (also known as countersunk finishing washers) are precisely engineered to accommodate countersunk screws, providing a flush, visually appealing finish while significantly increasing the load-bearing surface. Manufactured from premium-grade SS304, these washers offer exceptional corrosion resistance and durability, making them ideal for marine, automotive, machinery, and architectural applications. They prevent fasteners from tearing through material and protect the mating surface from scratching during tightening.

Technical Specifications

We supply a comprehensive range of standard sizes (DIN / ISO / ASME) and support fully customized dimensions to fit your specific engineering requirements.

Parameter	Specification Details
Material Grade	Premium 304 Stainless Steel (1.4301 / A2-70)
Standard	DIN 74, ASME B18.6.3, or Custom Drawings
Size Range	M3 to M20 (Metric) / #4 to 3/4" (Inch)
Surface Finish	Plain Clean / Bright Polished / Passivated
Hardness	≥ 140 HV
Application Screws	Flat Head Countersunk Screws / Oval Head Screws

Detailed Dimensions (Standard Sizes)

M3 / M4 / M5: Ideal for electronics, instruments, and precision brackets.
M6 / M8 / M10: Widely used in automotive, sheet metal fabrication, and outdoor furniture.
M12 and Above: Heavy-duty industrial applications and structural steel assemblies.

Key Features & Advantages

1. Superior Corrosion Resistance (SS304)

Utilizing authentic 304 stainless steel, these washers excel in humid, outdoor, and industrial environments without rusting. Material Test Certificates (MTC) can be provided upon request.

2. Perfect Countersunk Alignment

The precise stamping angle matches standard 90° or 82° countersunk screw heads perfectly. This ensures uniform pressure distribution and eliminates sharp protruding edges for a safer, cleaner joint.

3. Surface Protection & Flaw Covering

The wide rim distribution prevents the screw from pulling through soft materials (plastics, wood, thin sheet metal). It also conceals oversized or misaligned clearance holes, acting as a finishing trim.

4. Burrs-Free Smooth Finish

Advanced tumbling and polishing processes ensure the edges are smooth and completely free of burrs, preventing scratches during automated assembly lines or manual installation.

Typical Applications

Our B2B clients utilize these countersunk washers across various demanding industries:

Marine & Coastal Hardware: Boat fittings, deck hardware, and marine enclosures.
Industrial Machinery: Food processing equipment, chemical processing units, and automated machinery panels.
Architectural & Construction: Cladding systems, interior design trim, and metal structure facades.
Automotive & Aerospace: Trim panel attachments and light structural mountings.

Why Choose Us as Your Supply Partner?

Direct Factory Pricing: Benefit from a highly integrated supply chain in the Yangtze River Delta manufacturing hub, minimizing intermediary costs.
Strict Quality Control: Full dimensional inspection and chemical composition testing (Spectrometer verification) before shipment.
Flexible MOQ & Bulk Supply: Scalable production capacity capable of handling multi-million piece contract orders with consistent lead times.
OEM/ODM Customization: Simply send us your CAD drawings or physical samples, and our engineering team will handle tool/die development and sample production.

Packing & Logistics Options

Standard Export Packing: Inner plastic bags/boxes + Strong Master Cartons + Non-fumigation Wooden Pallets.
Custom Labeling: Barcodes, part numbers, and your company branding available on outer cartons.
Global Delivery: Flexible shipping terms including FOB, CIF, and CPT. Efficient routing from major ports (Ningbo/Shanghai) to global destinations.
