Threaded Shaft Collar 1-3/4-16

The Ruland Manufacturing TCL-28-16-F is a one-piece threaded shaft collar made from 1215 grade carbon steel. It fits a 1 3/4 inch bore with 16 threads per inch and uses a right-hand thread direction. Maintenance teams and machine builders use it to locate or secure components on threaded shafts.

Thermal Noise Power

The carbon steel body and alloy steel screw conduct heat away from the contact area during operation. No moving parts or lubrication points generate audible noise in normal service. Power draw is not applicable for this passive mechanical fastener.

Collar Dimensions

The collar outside diameter measures 2 3/4 inches with a clearance diameter of 3.05 inches and a collar width of 11/16 inch. These dimensions determine the space required for installation and the clamping surface available. California Proposition 65 warnings apply for cancer and reproductive harm.

Questions about this item

How do I install the 1-3/4-16 threaded collar onto a shaft, and what step is often missed?

Thread the collar onto the shaft by hand until snug, then tighten the alloy-steel set screw against the shaft flats; the step often missed is applying thread-locking compound to the set screw to prevent vibration loosening.

What maintenance or replacement will the carbon-steel 1215 collar need over time?

Inspect the set screw and threads periodically for wear or corrosion; replace the collar if the 1-3/4-16 threads show deformation or if the 11/16 in width face develops scoring that affects clamping force.

What limit appears first when the one-piece collar runs under sustained load?

The 3.05 in clearance diameter restricts adjacent components, so the first practical limit is physical interference before the carbon-steel 1215 material reaches its yield point under normal clamping loads.
