Value Collection 400-3437 Step Block Clamp Set 52 Pc

Product Description

The VALUE COLLECTION 400-3437 is a 52-piece step block and clamp set designed for securing workpieces on milling machines, drill presses, and other machine tool setups that use T-slot tables. The set uses 3/8-16 stud thread and fits 7/16 inch T-slots. Step blocks measure 1 inch in width, providing a stable base for setting clamp height across a range of workpiece thicknesses. Studs are available in six lengths — 3, 4, 5, 6, 7, and 8 inches — giving the machinist flexibility when clamping parts of varying profiles. This set is installed by machinists and toolroom technicians in production and job-shop environments.

This clamp set is suited for general-purpose workholding on manual mills, CNC knee mills, and drill press tables equipped with standard 7/16 inch T-slots. The range of included stud lengths and step block configurations supports clamping of flat stock, castings, and irregular workpieces during milling, boring, and drilling operations. The 11/16 inch T-slot nut width is sized to seat securely in the slot without rocking. The complete 52-piece count provides enough hardware to stage multiple setups simultaneously on a single table or across multiple machines.

Compatibility

Designed for use with milling machines, drill presses, and machine tool tables with 7/16 inch T-slots accepting 3/8-16 threaded clamping studs.

Installation Notes

Installation is performed by machinists or toolroom technicians as part of workholding setup. Power down and lock out the machine before arranging or adjusting any clamping hardware on the table. Position step blocks and clamps so clamping force is applied as close to the workpiece as possible, with the stud located between the clamp heel and the workpiece rather than far from the point of contact. Inspect studs and nuts for thread damage before each use and replace any worn components to maintain safe clamping force.
