I got a surprise today, using a "bolster style" screwdriver set, from Harbor Freight. (removing inspection cover from auger on Hesston 1014 Hydroswing = big Phillips-style screws)

I "assumed" that the steel shank would have gone ALL-the-way-though the blue plastic handle; well it doesn't = put a 15 mm wrench on "top hex" and it just spins inside the blue handle. (lower shank doesn't rotate.) What a joke.

I'll attach a similar photo:
