Gibraltar 20414G 52 Piece Step Block Clamp Set

Product Description

The GIBRALTAR 20414G is a 52-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, studs, nuts, and associated hardware sized for a 9/16-inch T-slot and a 3/8-16 stud thread. Stud lengths range from 3 inches to 8 inches, giving machinists flexibility to clamp workpieces of varying heights. The 1-inch step block width and 7/8-inch nut width are consistent throughout the set. Installed by machinists and toolroom technicians, this kit covers a broad range of fixturing setups without requiring individual component sourcing.

This step block clamp set is suited for light to medium-duty workholding in production and job-shop environments. It is commonly used on manual mills and CNC machine tables equipped with standard T-slot beds. The range of stud lengths — 3, 4, 5, 6, 7, and 8 inches — allows the set to accommodate parts with significant height variation in a single kit. The complete 52-piece count means full setups can be staged without additional hardware.

Installation Notes

Installation is performed by machinists or toolroom personnel. Ensure the machine table T-slot dimensions match the 9/16-inch specification before installing studs. Power down and lock out the machine before staging any workholding setup. Do not overtighten clamp nuts beyond snug-plus-firm hand-wrench torque without consulting the workpiece material and clamp manufacturer guidance.
