GB97 DIN125 Solid Brass Copper Flat Washer Plain Gasket Pad M2–M12
Solid brass (copper-zinc alloy) flat washers to GB97 / DIN125 standard. Brass washers combine corrosion resistance, electrical conductivity, and a warm golden aesthetic. The preferred choice for PCB grounding assemblies, electrical terminals, decorative hardware, and applications where galvanic compatibility with brass or copper fasteners is required.

Why Choose Brass Flat Washers?
- Electrically conductive — provides grounding path between PCB and chassis; compatible with brass standoffs and terminals
- Corrosion-resistant — brass resists corrosion in most environments; suitable for indoor and light outdoor use
- Galvanic compatibility — no galvanic corrosion when used with brass screws, standoffs, or copper terminals
- Warm golden aesthetic — complements brass hardware, decorative fixtures, and traditional furniture
- DIN125 / GB97 standard — same dimensions as steel and stainless washers; direct drop-in replacement
Typical Applications
- PCB grounding assembly (brass washer under screw head for chassis ground)
- Electrical terminal and bus bar assembly
- Decorative furniture and cabinet hardware
- Brass instrument and musical equipment assembly
- Marine hardware (brass is corrosion-resistant in saltwater)
- Plumbing and water fitting assembly
FAQ
Q: Can I use brass washers with stainless steel screws?
A: Yes, with caution. Brass and stainless steel have a low galvanic potential difference and are generally compatible in most environments. In saltwater or highly corrosive environments, use all-stainless or all-brass hardware to minimize galvanic corrosion risk.
Q: Are brass washers suitable for PCB grounding?
A: Yes. Brass is electrically conductive and is the standard material for PCB standoffs and grounding hardware. Use brass washers with brass standoffs and machine screws for a consistent, conductive PCB mounting assembly.
