Gibraltar 68006G 52 Piece Step Block Clamp Set

Product Description

The GIBRALTAR 68006G is a 52-piece step block and clamp set designed for workholding and fixturing applications on milling machines and machining centers. The set includes step blocks, clamp straps, studs, nuts, and washers sized to work with an 18mm T-slot. Studs are M16x2.0 thread and are available in six lengths: 80, 110, 125, 150, 175, and 200mm, giving the technician flexibility across a wide range of workpiece heights. The T-slot nut width is 29mm. The complete set weighs 29 pounds, making it a substantial, full-featured fixturing kit suited for production and job-shop environments.

This set is used wherever a workpiece must be clamped to a machine table for milling, drilling, boring, or grinding operations. It is appropriate for both manual and CNC machining setups in job shops, tool rooms, and production facilities. The range of stud lengths allows the set to accommodate stepped or irregular workpieces without supplemental hardware. Machinists, toolmakers, and setup technicians are the primary users of this type of fixturing kit.

Installation Notes

Setup and installation should be performed by a qualified machinist or toolmaker familiar with workholding practices.
