Easily cam out. No good. Need square drive or maybe torx. I couldn’t find those ones in my size, in real time. Do yourself a big favor and order from website. Things are grouped by brand in the stores
Bought to test if they could be used for Kreg pocket hole screwdriver adapter. The employee in hardware said they wouldn't work & I would need the more expensive Kreg screws. They were wrong - these worked great! I can also use them with a Philips head screwdriver. Very versatile!
