Installing Stem Casters
Stem casters also know as shank type casters come in two distinct styles. Type 1: caster stem threads up into leg, type 2: caster stem slips into socket sleeve and snaps in place. These stem casters do not utilize a plate for the furniture leg to sit on. The stem is held in place by a snug fit or socket sleeve.

Drill hole in furniture leg slightly smaller in diameter than diameter of drive stem. Depth should be approximately 1/4" deeper than length of caster stem.
It should fit a little tight as you want a good grip.
Threaded stem casters do not use a socket sleeve.
Useful on smaller diameter furniture legs as no caster plate is used.
