I haven't been using washers under my crank bolts -- should I?

Square-taper, that is.

All of the bottom brackets I've purchased in recent years (Shimano, IRD, Velo-Orange, and Tange-Seiki) included bolts like this, with no separate washers:



So I haven't been using any on my bikes. I haven't had any cranks come loose, ever, whether they had been installed for two months or two years. And there is always a reassuring amount of effort needed to crack the bolts loose when I do want to take the cranks off for any reason. It's for that reason that I hadn't given it much thought in 7 or so years of riding and fiddling with bikes.

On the occasion of reassembling my long-distance bike, it occurred to me to think about it, though. Is there a good reason to start using separate washers when installing my cranks, or should I keep doing what I'm doing?

Thanks.


P.S. Just did a little more Googling, and learned that crank bolts like mine are called "flange bolts" -- does the large flat area on the back of the head obviate the need for washers, then?
