Te-co 20218 50 Piece Step Block Clamp Set 3/4-10 Stud

Product Description

The TE-CO 20218 is a 50-piece step block and clamp set designed for workholding and fixturing applications on milling machines, drill presses, and machining center tables. The set includes step blocks, clamps, studs, nuts, and related hardware needed to secure workpieces to T-slot tables without sourcing components separately. Step blocks measure 1-1/2 inches wide and accept a 7/8-inch T-slot. Studs are threaded at 3/4-10 and are available in six lengths - 3, 4, 5, 6, 7, and 8 inches - to accommodate varying workpiece heights and setups. The full set weighs 54 pounds. Construction is steel throughout.

This set is suited for production shops, tool rooms, and job shops where versatile fixturing capability is needed at a single workstation or across multiple machines. The range of stud lengths allows machinists to fixture parts of significantly different stack heights without swapping hardware kits. A 1-1/2-inch nut width is used throughout the set for consistent wrench sizing. The set is appropriate for general-purpose manual machining as well as CNC milling table setups where T-slot clamping is the preferred workholding method.

Key Features

• 50-piece complete set - includes step blocks, clamps, studs, nuts, and hardware
• Steel construction throughout for rigidity and durability under clamping load
• 1-1/2-inch step block width with 7/8-inch T-slot fitment
• 3/4-10 stud thread for standard machining table compatibility
• Six stud lengths (3, 4, 5, 6, 7, and 8 inches) for flexible stack height adjustment
• Consistent 1-1/2-inch nut width across the set for single-wrench operation

Compatibility

Designed for use with T-slot milling tables and machining center tables accepting a 7/8-inch T-slot. Verify T-slot width on your machine table before installation.

Installation Notes

Installation is performed by machinists or toolroom technicians. Power down and lock out the machine spindle before adjusting or repositioning clamps on the table. Ensure the stud length selected provides adequate thread engagement with the T-nut and clamp nut without bottoming out. Distribute clamping force evenly across the workpiece to prevent distortion, and torque fasteners only to the point required for positive workholding - overtightening can damage T-slots or distort the workpiece.
