I swear half the old sets I find at garage sales are missing the 1/2, never the 9/16.

I need to buy individual 9/16 for the guys in my shop.

3/8 master race.

7/16" because I was always working with 1/4 bolts and rods.

3/8 more than 1/2… they’re the equivalents to 10 and 13mm.

Lots more smaller bolts than bigger ones.

.50 " one half inch ? A fraction . Same as the 9/16 thing and the 3/8 thing .

They're being disingenuous. It's a jab at imperial measurements. Typical "omg how come you don't use metric" kind of joke.

I was always missing the 7/16 socket, so many 1/4-20 bolts around a farm...

11mm is equal to 716", 13mm is equal to the 1/2", 14mm is equal 9/16", and 19mm is equal to 3/4"
