Flat Washer M30 Pack 100

These ISO EN 14399-6 compliant flat washers fit M30 bolt sizes with a 31.00 mm inside diameter and 56.00 mm outside diameter. Each washer measures 5 mm thick and is made from carbon steel with a plain finish. The pack contains 100 pieces for high-volume fastening requirements.

Suits M30 metric assemblies needing load

Buyers working with imperial bolt sizes or smaller metric threads should look elsewhere. This pack does not suit applications requiring lock washers, spring washers or specialised sealing washers. Projects needing fewer than 100 units may find the quantity excessive.

Carbon steel construction handles standard

The 5 mm thickness provides adequate bearing surface for typical structural connections. The plain finish offers no corrosion protection beyond the base metal, so outdoor or marine environments will require additional coating. California Proposition 65 warnings apply for cancer and reproductive harm.

Questions about this item

What bolt size must I already have for these M30 flat washers to fit?

They are made for M30 bolts, with a 31.00 mm inside diameter that matches that thread size.

Will these ISO EN 14399-6 washers work with older metric fasteners I keep in stock?

Yes, the ISO EN 14399-6 standard covers metric dimensions, so they fit existing M30 hardware that follows the same standard.

How can I confirm the washers meet the 56.00 mm outside diameter after unpacking?

Measure the outer edge with a caliper; it should read 56.00 mm, and the thickness should be 5 mm.
