H&R Mfg 82-2.5 4"OAL 1-3/4"OAW Set of 3 Serrated Soft Lathe Chuck Jaws

This is a new set of three (3) H&R Manufacturing (H&R Mfg. and Supply, Inc.) soft lathe chuck jaws, model 82-2.5, sold via MSC Industrial Supply under MSC part number 82450503 and weighing 12 lbs per the packaging label visible in the photos. Each jaw features a serrated top surface (cross-hatched knurl pattern) for positive grip against master jaw serrations, two threaded mounting holes on the clamping face spaced 1.181" apart, an overall length (OAL) of 4", and an overall width (OAW) of 1-3/4". Soft jaws are made from machinable steel, allowing the operator to bore the gripping surface to a precise workpiece diameter for superior concentricity and reduced part distortion—particularly important for thin-walled, finished, or irregularly shaped workpieces. The "82" prefix in the part number designates the chuck size series (consistent with an 8" or 8-1/4" scroll chuck body), while "2.5" indicates the jaw height designation; these jaws mount to compatible master jaw bases on scroll or power chucks of the appropriate series and bolt pattern.
