What size washer do I need for my bolt?

Choose a washer with an inner diameter slightly larger than your bolt diameter. For example, use M6 washers with M6 bolts. The outer diameter should be appropriate for the surface you're protecting.

Can brass washers be used with steel bolts?

While physically compatible, mixing brass and steel can cause galvanic corrosion in wet environments. Use brass washers with brass fasteners, or ensure proper isolation with coatings.

What's the difference between flat and spring washers?

Flat washers distribute load and protect surfaces. Spring washers provide tension and prevent loosening due to vibration. For best results, use a flat washer under a spring washer.

Are these washers suitable for outdoor use?

Yes, brass washers are excellent for outdoor use. They resist corrosion from rain, humidity, and temperature changes better than steel alternatives.

Can I use brass washers in high-temperature applications?

Brass washers can handle temperatures up to 200°C. For higher temperatures or extreme conditions, consult our engineering team for special alloy recommendations.
