what is a fender washer? in which situation is it used?


Common name for a washer larger than an ordinary washer for the same
diameter bolt. It is used for special purposes and to spread the bearing
load, as on a wood or composite bearing surface.

Thus we use "fender washers" or "970's" on a composite bulkhead where we
are fastening a hydraulic accumulator or on a wooden bulkhead so as not to
crush the fibers.

Of course a "fender" washer may not be legal for aircraft use. Always use a
cad-plated AN 970 washer purchased from a reliable source.

A hardware store washer will be just fine as long as the purpose and use is understood. This is the homebuilt forum,
right? Nothing illegal about its use at all....

Now safety is an entirely different matter....

You're right, Mr. Blueskies. I stand corrected. Cad plating on a washer
is unnecessary but it sure helps on the bolt and nut.

Most if not all washers I see in the hardware stores are plated, if not Cad then nickel. I don't recall seeing any plain
ones lately...

Lowes and Home Dee-pot are *not* hardware stores. . . ;-)

That's true.....but they're the closest thing to a hardware store that I have
seen for many years. Where did all the GOOD hardware stores go.

I went into Menards a few weeks ago looking for a 3 inch V-belt pulley for an
air compressor. The person who waited on me had no idea what a pulley was.
He started showing me ratchet cable "pullers"....like a "come-along." Last
month I went into the same store and asked if they carried tap and die sets.
Again...the person who waited on me didn't have a clue as to what I was talking
about.

I miss the days when I could take an obscure looking part into the store, and
the clerk (usually the owner) knew exactly what it was and how it was used.
There just aren't any stores like that around anymore.

I must sound like an old f*rt reminiscing about the good old days. I am a
YOUNG 47 year old male.

The only ones around the Northwest are McLendon's chain of stores
http://www.mclendons.com/. They *train* their staff!

We have a really good Ace Hardware store here. I know they are struggling with Menards, The Home Depot, and Lowes within
4 miles. I use them every chance I get...

I thought the cheap hardware store hardware (nuts/bolts/washers
anyway) was zinc plated. Sometimes the really cheap stuff flakes off...

If you've found nickel plating, that's a pretty good thing. Maybe I
gotta look closer next time I'm at the store.

The VAST majority are bright zinc plated.
