Gibraltar 20416G 52 Piece Step Block Clamp Set

Product Description

The GIBRALTAR 20416G is a 52-piece step block and clamp set designed for workholding and fixturing applications on milling machines and drill presses. The set includes step blocks, clamp straps, T-bolts, and nuts sized to work with a 3/4 inch T-slot and a 5/8-11 stud thread. Step block width is 1 inch, with nut width of 1-1/4 inches. Stud lengths included span 3, 4, 5, 6, 7, and 8 inches, giving the technician flexibility to accommodate a wide range of workpiece heights. The complete kit weighs 29 pounds. Machinists and toolroom professionals use this set to secure parts firmly to machine tables during cutting operations.

This set is suited for job shop, maintenance, and production machining environments where reliable part clamping is required. The variety of stud lengths allows the operator to configure the clamps for thin stock or tall workpieces without sourcing individual components separately. The 3/4 inch T-slot sizing fits a common standard found on many manual vertical mills and drill press tables. The full 52-piece count provides enough hardware to set up multiple clamping positions simultaneously.

Installation Notes

Installation is performed by machinists or toolroom technicians. Power down and lock out the machine spindle before adjusting or configuring any workholding setup. Tighten T-bolts and clamp nuts securely to prevent workpiece movement during cutting, but do not overtighten to the point of distorting the step blocks. Follow the machine manufacturer guidelines and applicable shop safety standards when setting up fixturing.
