Can I use a washer with this bolt?

Yes. A matching M6 hot dipped galvanised washer can be added under the nut to spread the load.

Is it suitable for outdoor use?

Yes, the hot dipped galvanised finish provides corrosion resistance for exterior applications.

Would buy again for sure

Was a bit skeptical ordering online but really glad I did. The item arrived in a sturdy box — nothing rattled or was damaged. Set it up in about 10 minutes and has been working perfectly since. Compared to what I saw in store I saved a solid amount. Will definitely be back.
