Threaded Steel Shaft Collar

The Ruland Manufacturing TCL-16-8-F is a one-piece carbon steel collar designed for inch-series shafts. Its 1-8 right-hand thread mates with matching threaded rods or shafts in power-transmission assemblies. Grade 1215 steel construction suits general-purpose clamping and positioning tasks in machinery and automation.

Verify Shaft Thread and Clearance

Confirm the host shaft carries a 1-8 thread before ordering. The collar’s 2.03 in clearance diameter and 1/2 in width determine the space it occupies on the shaft. Ensure adjacent components can accommodate these dimensions without interference.

Alloy Steel Screw Secures Assembly

The included alloy steel screw locks the collar firmly in place, preventing axial drift under vibration. Its one-piece design frees up radial space compared with split collars, simplifying installation on long threaded shafts where sliding a collar from the end is impractical.

Questions about this item

What comes in the box with the TCL-16-8-F shaft collar and is any additional hardware required?

The package contains one 1-piece carbon steel shaft collar with an integral alloy steel set screw. No extra hardware is needed for installation.

How do I choose between the available thread sizes for this collar?

This model is supplied only with a 1 in.-8 right-hand thread; select it when your shaft matches that exact thread specification.

What does the 2.03 in clearance diameter mean when the collar is mounted on a shaft?

It is the maximum outside dimension the collar presents after tightening, so adjacent components must allow at least 2.03 in of radial space.
