Value Collection 400-3740 Step Block Clamp Set 52 Pc

Product Description

The VALUE COLLECTION 400-3740 is a 52-piece step block clamp set designed for workholding applications on milling machines and machining centers equipped with T-slot tables. The set uses 5/8-11 stud thread hardware and fits 11/16-inch T-slots, providing a secure clamping solution for fixturing raw stock, castings, or machined parts to a work table. Step blocks measure 1 inch wide, and studs are available in six lengths ranging from 3 inches to 8 inches, giving machinists the flexibility to clamp workpieces of varying heights. The full set weighs 29 pounds. This kit is a practical solution for job shops and toolroom environments where versatile, quick-setup workholding is required.

This clamp set is suited for use on knee mills, bed mills, and similar machine tools with standard T-slot tables. The range of included stud lengths makes it applicable across a variety of part heights and fixturing configurations. The set is intended for installation and use by machinists, tool and die makers, and CNC setup technicians in production or prototype environments. Nut width is 1-1/8 inches, compatible with standard open-end or box-end wrenches commonly found in machine shop tooling.

Compatibility

Designed for use with milling machines and machining center work tables equipped with 11/16-inch T-slots accepting 5/8-11 threaded studs.

Installation Notes

Installation is performed by machinists or CNC setup technicians. Before securing a workpiece, confirm the machine table is clean and free of chips or debris that could affect clamp seating. Tighten stud nuts firmly with an appropriate wrench to prevent workpiece movement during cutting operations, but do not over-torque in a way that risks damaging the T-slot or stud threads. Always verify that clamps and step blocks are clear of the tool path before initiating a machining cycle.
