I know this is dumb question but here goes. I know what the hammer side of a ball peen hammer head is used for but what is the peen side mostly used for?

works good for fixing the bolt holes on stamped steel valve covers and oil pans that have been over-torqued.

Rivets when I was in the seventh grade metal shop they taught us how to rivet a sheet metal pan I recently riveted the straps on my tailgate the same way

Ball-peen. As opposed to a cross-peen or straight-peen hammer. Get into shape. ;)

Shrinking over sized reamed holes a ball bearing works well all sow.

As said............

It goes back to the days of on site riveting.
The ball end was the right shape to get a straight through rivet into the desired mushroom shape.
At one time riveting was much more common then it is now.
That is why you see all kinds of sizes in the hammers.
It was used in everything from airplane sheet metal to the Empire State Building steel work.

ball peen hammers most important use is for Rotor retaining screws that are SEIZED up!

Set the ball end against it and wack the flat end with another hammer. Doesn't mess up the screw too bad and turns right out

Hammer face to hammer face is a bad idea. :eyecrazy:

guess they didn't teach you sentence structure, as in periods, and capital letters to begin sentences...

Pein side is great for glancing blows, when you can't get a straight shot.

I use it often hammering balljoints out of steering knuckles etc.

The ball peen hammer's heads should be softer, as they are intended to strike hardened tools like chisels.

Carpenters' hammers are hardened, to strike softer wire nails.

You are not supposed to strike two claw hammers together, although I believe Mythbusters determined this is not a big deal.

EDIT: I was curious and looked for info on the Mythbusters episode. Result: I found so many postings from people with first hand or personal knowledge of injuries and eyes lost to chipped hammer faces that I say Mythbusters totally screwed the pooch on this one. Don't do it.

How about an alternate use....since I just did this in my kitchen.

Use the ball peen head to make a nice uniform divot wherever you have nail/screw holes in drywall. Hitting the flat face with the palm of your hand provides enough force. Then you can fill the divot with spackle and sand down to a perfectly flush surface finish before priming and painting.

That's what the handle end of the spackle knife is for.

ball peen was invented to peen the metal when welding, you weld and then strike the weld with the peen to keep it from cracking
