Gibraltar 20206G 50-piece Step Block Clamp Set

Product Description

The GIBRALTAR 20206G is a 50-piece fixturing step block and clamp set designed for workholding applications on milling machines, drill presses, and machining centers. The set includes step blocks, clamps, T-nuts, studs, and hardware sized for a 5/8-inch T-slot with a 1/2-13 stud thread. Step block width is 1 inch, and stud lengths cover a range from 3 inches through 8 inches, giving machinists flexibility when securing varied workpiece heights. The complete set weighs 23 pounds. It is intended for use by machinists, toolmakers, and machine shop technicians who need a ready-to-use fixturing solution without sourcing individual components.

This set is suited for production and job-shop environments where workpieces of different thicknesses must be clamped to machine tables with standard 5/8-inch T-slots. The graduated stud lengths — 3, 4, 5, 6, 7, and 8 inches — accommodate a wide range of part heights. The 1/2-13 thread is a common inch-series coarse thread, compatible with standard T-nuts and clamp hardware found in most machine shop inventories. The set provides a full complement of components needed to set up multiple clamping stations simultaneously.

Compatibility

Designed for use with machine tables featuring standard 5/8-inch T-slots. Compatible with any fixturing application requiring 1/2-13 stud thread hardware.

Installation Notes

Installation is performed by machinists or toolmakers as part of machine setup. Power down and lock out the machine before positioning workpieces and tightening clamps. Ensure the step block height is matched to the workpiece so the clamp applies force at or near the workpiece surface, not at the stud. Do not over-torque the stud nuts; apply firm, even clamping force and verify workpiece rigidity before beginning a cut.
