1.Who We Are

For 15 years Goshen Hardware has lived one mission: turn a “simple” washer into the most reliable, cost-saving gram of metal in your assembly. Today our 8000-m² ISO 9001 & IATF 16949 plant stockpiles 1.2 billion washers in 28 alloys and 5,000+ active sizes—ready for next-day despatch to 63 countries.

2.What Leaves Our Dock

• Stainless 304 / 316 / A4—marine, medical, food-line.
• Brass & C360 Free-Cutting—electrical ground, decorative gold tone.
• Copper, Phosphor-Bronze—thermal/EMI management for EV & solar.
• Carbon & Spring Steel—hardened, zinc, Cr+3, Geomet, DAC, hot-dip.
• Aluminum, Titanium, Monel—weight-critical or caustic zones.
• Rubber-bonded, Nord-Lock, Belleville, shim packs—specialty solutions.
