take short screws with you to home depot and go "give me something bigger!"
Make sure you are not holding your hands near your crotch when you ask this.
Grab a couple of nuts sized for the new screws incase the ones you walk out of the store with are a tad too long, you'll be able to use the nuts as spacers.
*facepalm* I so should not have lead this post with that joke.
Be safe not just with yourself, but those you play with. If you are reckless with other peoples safety then you will leave.
