For those of us using 1/4" peg boards, the anchors provided can be used to secure most of them so they don't fall off. I say most because the anchors use holes to the left and right of the hook.. For hooks using two holes, you can still secure them down using an adjacent hole that's in use--there's still plenty of slack room in a 1/4" hole to accommodate the anchor.

I do think the lack of directions on how to use the anchors can leave some folks confused. But it took me about 10 seconds to figure it out, based on the shape of the anchor.  There is a notch which tells you this is where the hook goes.. So the two ends must go into a hole, one goes in first because of it's double hooked shape. The other end locks it down.

 It's not a perfect solution though because there are some accessories that can't be locked down because their vertical wire position (where the notch goes) can be in-between two holes, so the ends of the anchor hooks do not line up to go into the adjacent holes. The listing said they work, but it's not entirely true.. Some hooks that use two holes cannot be anchored down and therefore will fall out easily.

While $10 for 51 hooks seems like a great value, there were 10 or so L hooks that I find useless and unsafe.. L hooks don't really hook, they just stick out and things can slide right off when jarred.

I recommend those of us with 1/4" pegboard to buy the following set - Dorman Hardware 4-9820 Peghooks, Value-Pack, 28-Piece.  They are only $6.99, so you spend a little more (buying two) than these, but they'll fit much better.
