Te-co 20413 52 Piece Step Block Clamp Set 3/8-16

Product Description

The TE-CO 20413 is a 52-piece fixturing step block and clamp set designed for workholding applications on milling machines, drill presses, and machining centers. The set includes step blocks, clamp straps, studs, nuts, and washers sized for 1/2 inch T-slots with 3/8-16 stud thread. Step block width is 1 inch, and stud lengths cover 3, 4, 5, 6, 7, and 8 inches to accommodate a wide range of workpiece heights. The nut width is 7/8 inch. This set is installed by machinists and tool-and-die tradespeople who need a complete fixturing solution without sourcing individual components.

This clamp set is suited for use on manual mills, CNC machine tables, and surface plates where 1/2 inch T-slots are present. The range of stud lengths makes it practical for holding workpieces of varying thicknesses. Having multiple stud lengths in a single kit reduces setup time when switching between jobs with different stack heights. The set is appropriate for both production environments and job-shop applications where fixturing configurations change frequently.

Installation Notes

Installation is performed by machinists or tooling technicians. Ensure the machine table is powered off and the spindle is fully stopped before adjusting or repositioning clamps. Step blocks and clamp straps should be positioned to apply clamping force as close to the workpiece as possible to minimize flex. Follow shop safety standards and consult machine tool manufacturer guidelines for maximum allowable clamping loads on the table surface.
