Climax Metal Products H2C-275 Two-Piece Clamping Collar Recessed Screw

SKU CH-1TJC-BHMCC

Two-piece carbon-steel clamping collar fits a 2 3/4 in shaft and uses recessed screws for a flush profile

  • Two-piece design simplifies installation and removal on mounted shafts
  • Recessed screw heads protect fasteners from external damage and snagging
  • Carbon steel construction with grade 1211 material delivers high strength for power transmission
  • 25 in outside diameter and 3/4 in width provide secure clamping on 2 3/4 in round bores
  • Inch-system dimensions ensure direct compatibility with standard imperial shafting

Shaft Collar for 2 3/4 Inch Shafts

The Climax Metal Products H2C-275 is a two-piece clamping collar designed to secure components on round shafts with a 2 3/4 inch bore diameter. Its carbon steel construction uses grade 1211 material for the collar and matching carbon steel screws. The recessed screw design keeps fastener heads flush with the collar surface.

Two-Piece Design for In-Place Installation

The split construction allows the collar to be fitted or removed without sliding it over the end of the shaft, saving disassembly time on existing assemblies. It provides a 4 1/4 inch outside diameter and a 3/4 inch collar width, requiring sufficient radial space around the mounting point. The 4.25 inch clearance diameter must be accommodated by adjacent hardware.

Suited for Inch-Series Power Transmission Builds

This collar suits maintenance teams and machine builders working with inch-dimension shafts who need a reusable, high-grip clamping solution without keyways. It is not intended for metric shafts, threaded bores, or applications requiring a keyway slot. Buyers needing a one-piece solid collar or a different bore size should look elsewhere.

Questions about this item

How does the 275 carbon steel grade limit sustained clamping force?

Grade 1211 carbon steel provides consistent clamping strength without permanent deformation under normal sustained loads.

What heat or noise appears when the 4.25 in collar runs continuously?

The carbon steel collar produces no operational heat or noise since it has no moving parts or power source.

Which shaft diameter must already be in place for the 2 3/4 in bore to clamp?

A precise 2 3/4 inch round shaft is required for the two-piece collar to engage properly.
