Gibraltar 20214G 50 Piece Step Block Clamp Set

Product Description

The GIBRALTAR 20214G is a 50-piece fixturing step block clamp set designed for workholding applications on milling machines, drill presses, and similar machine tool setups. The set accepts a 5/8-11 stud thread and fits an 11/16 inch T-slot, making it compatible with standard T-slotted machine tables. Step blocks are 1-1/2 inches wide, and the included studs cover six lengths: 3, 4, 5, 6, 7, and 8 inches, giving machinists the reach needed for a wide range of workpiece heights and clamping configurations. Nut width is 1-1/8 inches. At 44 pounds, the set provides a comprehensive complement of hardware for a fully equipped toolroom or production setup.

This set is used in machine shops, toolrooms, and production environments where workpieces must be rigidly secured to a machine table for milling, drilling, or boring operations. The variety of stud lengths allows technicians to step up or step down clamp height to match irregular workpiece profiles. The set is suited for both job-shop versatility and dedicated fixturing on machining centers with standard T-slot tables.

Installation Notes

Installation is typically performed by a machinist or toolroom technician. Before setting up any workholding fixture, confirm the machine is powered off, the spindle is stationary, and all guards are in place. Inspect each stud, nut, and clamp for damage before use, and ensure the step block height is matched as closely as possible to the workpiece height to maximize clamping force and minimize deflection. Follow applicable shop safety standards and machine manufacturer guidelines when securing workpieces to the table.
