Te-co 21002 Step Block Clamp Set 13 Piece Fixturing

Product Description

The TE-CO 21002 is a 13-piece fixturing step block clamp set designed for workholding applications on milling machines, drill presses, and other machine tool setups. The set includes 6 serrated end clamps, 6 step blocks, and a holder, giving a machinist or toolroom technician everything needed to secure a workpiece directly to a T-slot table. Step blocks measure 1 inch in width and are paired with 1/2 inch stud thread hardware. The serrated clamp faces grip the workpiece or fixture reliably under cutting loads, reducing the risk of movement during machining operations.

This set is suited for general-purpose fixturing in job shops, production toolrooms, and maintenance machining environments. It handles clamping capacities from 3/4 inch up to 6 inches, making it flexible enough for a wide range of workpiece heights. Trade machinists and toolroom setters use kits like this for quick setups on vertical mills and drill press tables where T-slots are present. The complete set format eliminates the need to source clamps and blocks separately.

Key Features

• 13-piece complete set: 6 serrated end clamps, 6 step blocks, and 1 holder
• Step block width of 1 inch for standard T-slot table compatibility
• 1/2 inch stud thread hardware throughout the set
• Clamping capacity range of 3/4 inch to 6 inches to accommodate varied workpiece heights
• Serrated clamp face improves grip and reduces workpiece slippage under load

Compatibility

Designed for use with standard T-slot machine tables on vertical milling machines, drill presses, and similar machine tools that accept 1/2 inch stud thread fixturing hardware.

Installation Notes

Step block clamp sets are installed and adjusted by machinists or toolroom technicians. Before adjusting or repositioning clamps, ensure the machine is powered down and the spindle has come to a complete stop. Verify that the stud thread engages fully into the T-slot nut before applying clamping torque, and check that the clamp rests as level as possible across the workpiece and step block to distribute load evenly. Follow applicable shop safety standards and machine tool manufacturer guidelines for workholding setup.
