Kurt AJ400-236 Double Step Fixed Vise Jaw 4 Inch

Product Description

The KURT AJ400-236 is a double step fixed vise jaw designed for use with 4-inch vises in machine shop and industrial workholding applications. Manufactured from steel, this bolt-on jaw measures 3.969 inches wide, 1.374 inches high, and 0.547 inches thick. The double step profile provides two distinct gripping surfaces - a 0.25-inch step and a 0.5-inch step - allowing machinists to secure workpieces at different heights without repositioning the vise. It is installed as a fixed jaw replacement or upgrade by machinists, toolroom technicians, and CNC operators.

This jaw is suited for production and job shop environments where consistent workholding at multiple step heights is required. The fixed jaw configuration keeps the workpiece stationary against the moving jaw, making it appropriate for milling, drilling, and light grinding operations. The bolt-on attachment method allows straightforward field replacement without specialized tooling. Compatible vise size is 4 inches, matching standard Kurt-style and similarly dimensioned vise bodies used across general machining operations.
