Te-co 20417 52 Piece Step Block Clamp Fixturing Set

Product Description

The TE-CO 20417 is a 52-piece step block and clamp fixturing set designed for workholding applications on milling machines, drill presses, and other machine tool setups. The set uses 1 inch step blocks, a 13/16 inch T-slot width, and 5/8-11 stud thread pitch, with a 1-1/4 inch nut width. Stud lengths included are 3, 4, 5, 6, 7, and 8 inches, giving machinists a wide range of clamping heights for holding workpieces of varying thickness. The complete set arrives as a packaged unit, ready for immediate use at the machine table. Machinists and toolroom technicians are the primary installers of this type of workholding equipment.

This fixturing set is suited for use in machine shops, toolrooms, and production environments where parts must be secured directly to T-slotted machine tables. It covers a broad range of workpiece heights by pairing step blocks and clamps at different stud lengths. The 5/8-11 thread is a common size across many domestic and import machine tools, making this set a practical general-purpose addition to a shop inventory. Both manual machinists and CNC setup technicians will find this set applicable to standard T-slot table work.

Installation Notes

Installation is performed by machinists or toolroom technicians as part of standard workholding setup. Always power down and lock out the machine before positioning clamps and tightening hardware on the table. Ensure studs are fully engaged in the T-slot and that clamps are positioned as close to the workpiece as possible relative to the step block for maximum clamping force. Follow shop-specific workholding procedures and any applicable machine tool safety standards.
