Threaded Stem Casters should NOT be used as a “Leveling Device”! The weight is supposed to sit at the bottom of the stem on the swivel bearing. A properly installed threaded stem is fully supported the length of the stem.
When you put your mouse over the words in the wheel description column you see a picture of the wheel.

We do NOT include mounting Hardware.

















Capacity up to 300 pounds per caster. These institutional stem casters are ideal for most types of institutional equipment, and are offered with a wide selection of wheels.
T-Nuts for Threaded Stems:
T-Nuts can be used to secure our threaded stem casters to wooden items. Here we show the typical use of the T-Nut for both a Horizontal and a Vertical Application.
In the Horizontal Application, you would drill a hole equal to the diameter of the barrel of the T-Nut and completely thru your wood. Hammer the T-Nut into the hole and thread your caster in from the bottom. This is the strongest mounting.
The Vertical Application is for attaching casters to the bottom of legs and into the end grain of the wood. This is not an exceptionally strong way to mount! Drill your hole equal to the diameter of the barrel of the T-Nut and to the depth of the length of the stem of the caster plus about 1/4″. Apply 2 part epoxy to the T-Nut for additional strength. Hammer the T-Nut into the hole and thread your caster in from the bottom. You must use epoxy as we have had problems with some woods where the nuts ( and the casters ) fall off.

Typical Applications:
“You should never select on the basis of load capacity alone. There is no industry standard for load capacity ratings and they may not include a factor for abuse. Our capacity ratings are below what the casters are capable of carrying because most applications have less than perfect conditions. Please refer to the information shown at the bottom of this page. If you have any doubt as to which wheel or caster is the BEST choice for your application contact us for a recommendation.”
