Value Collection 400-3639 Step Block Clamp Set 52 Pc

Product Description

The VALUE COLLECTION 400-3639 is a 52-piece step block and clamp set designed for workholding applications on milling machines, drill presses, and similar machine tools. The set uses 1/2-13 stud thread and fits 11/16-inch T-slots, making it compatible with a wide range of standard machine tables. Step blocks measure 1 inch in width and are used in combination with the included serrated end clamps and studs to secure workpieces firmly to the table surface. The full set weighs 27 pounds and provides the hardware needed to handle a variety of clamping heights and configurations without sourcing individual components separately.

This set is suited for machine shop environments, toolroom work, and production setups where workpieces of varying heights and profiles need to be fixtured securely. Included stud lengths of 3, 4, 5, 6, 7, and 8 inches allow techs and machinists to adjust clamping height to match the step block configuration. The set covers common clamping scenarios encountered in both job shop and light production machining without requiring additional hardware for most standard setups.

Key Features

• 52-piece set includes studs, coupling nuts, flange nuts, serrated end clamps, step blocks, and T-slot nuts in one package
• 1/2-13 stud thread is a widely used standard for milling machine workholding hardware
• Fits 11/16-inch T-slots found on many standard machine table configurations
• Six stud lengths (3, 4, 5, 6, 7, and 8 inches) accommodate a range of clamping heights
• Step block width of 1 inch with T-slot nut width of 1-1/8 inches for stable, repeatable clamping
• Complete kit format reduces setup time by providing all mating components pre-matched to the same thread standard

Compatibility

Designed as a standard replacement and general-purpose workholding set for machine tables with 11/16-inch T-slots and 1/2-13 thread studs, which are common specifications on manual milling machines and drill presses.

Installation Notes

Installation is performed by qualified machinists or machine tool operators. Before mounting or adjusting any workholding hardware, ensure the machine is powered down and the spindle is fully stopped. Studs should be seated fully in the T-slot nuts before tightening clamps, and flange nuts should be torqued evenly to prevent workpiece movement during cutting operations. Follow applicable shop safety procedures and machine manufacturer guidelines when setting up workholding fixtures.
