Hertel CH-301-A Straight Line Action Clamp 100 Lb Steel

Product Description

The HERTEL CH-301-A is a standard straight line action clamp designed for workholding and fixturing applications in machining, fabrication, and assembly environments. It delivers 100 lb (444.82 N) of holding capacity through a linear plunger action with 0.6575 inches of travel. The plunger diameter is 0.252 inches with internal M4 thread and a round profile. The clamp body is steel with a zinc finish coating and features a straight red handle with 180 degrees of handle movement. It ships with one spindle and two nuts. Typically installed by machinists, tool and die technicians, and fixturing specialists, this clamp suits production environments where repeatable clamping force and compact footprint are required.

The CH-301-A fits applications requiring a flanged base mount in tight fixture layouts. The flanged base includes three mounting holes at 0.172 inches diameter, with hole spacing of 0.625 inches on the length axis and 0.626 inches on the width axis. The base measures 1.311 inches in length and 1.063 inches in width. Overall clamp dimensions are 2.679 inches in length, 1.59 inches in height, and the plunger centerline height is 0.5 inches. The spindle length is 0.748 inches. This clamp is suited for light-duty toggle and straight-pull clamping setups on jigs, fixtures, and machining pallets.
