Te-co 40104 Steel Step Block 2.5 to 6 Inch Height Adjustment

Product Description

The TE-CO 40104 is a 2-piece steel step block designed for workholding applications in machining and milling setups. It provides a height adjustment range of 2.5 to 6 inches, allowing the operator to match the block height to the workpiece and clamp configuration quickly. The block is machined from steel for rigidity under clamping load. With a base depth of 3.75 inches and an overall width of 1 inch, it fits standard T-slot table arrangements used with serrated end clamps. Step depth measures 0.0625 inches and step elevation measures 0.125 inches per increment. Machinists and tool-room technicians working with manual or CNC milling equipment are the primary installers.

This step block is used in machine shop environments where workpieces must be elevated and secured at a precise height before milling, drilling, or boring operations. It functions in conjunction with serrated end clamps, which bear against the stepped profile to hold the workpiece firmly against the table. Larger sizes in the TE-CO 40104 series feature chamfered holes for easier bolt insertion during setup. The 2-piece format allows the two halves to be stacked and adjusted independently to dial in the required working height.

Key Features

• Height adjustment range of 2.5 to 6 inches in a 2-piece configuration
• Steel construction provides rigidity and durability under clamping loads
• Designed to work in conjunction with serrated end clamps
• Step depth of 0.0625 inches and step elevation of 0.125 inches per step
• Chamfered holes on larger sizes for ease of bolt insertion
• Base depth of 3.75 inches and overall width of 1 inch for stable footing on the table

Compatibility

Designed for use with serrated end clamps in standard T-slot milling table workholding setups. Compatible with common step block and strap clamp kits used in manual and CNC machining environments.

Installation Notes

Installation is performed by machinists or tool-room technicians as part of workholding setup. Power down and lock out the machine spindle before arranging or adjusting clamps and step blocks on the table. Position the step block so the serrated end clamp seats fully against a step without overhang. Inspect block and clamp contact surfaces for chips or debris before applying clamping force to ensure a stable, even hold.
