Metric Safety Washers

[Jason C. Wells]

I am trying to locate a manufacturer/supplier of metric safety washers like the ones shown here:

Who makes these? The only supplier I have found for metric units is an ebay store, McGill Motorsports. It would be nice to find a North American source.

Regards,

Never seen these before over in the UK.

Why don't you just get the nearest imperial equivalent and either use them straight out of the box or slightly enlarge the hole:

10-32 = 5mm
1/4" = 6.35mm, probably OK for M6
5/16" = 7.9mm, enlarge slightly for M8
3/8" = 9.5mm, enlarge slightly for M10
7/16" = 11mm, enlarge for M12
1/2" = 12.7mm, may be OK for M12

Its a little bit of messing around but if you can't get metric...

Don't forget to run a lightly oiled rag thru the bore as you will have removed the Irridite anti-corrosion surface treatment.

Just following up to myself for the benefit of the audience. After receiving a few emails from a variety of suppliers I think that these are a custom order item. It appears that race shops have them manufactured for their stock.

Cheers,
