Value Collection 400-3456 Step Block Clamp Set 52 Pc

Product Description

The VALUE COLLECTION 400-3456 is a 52-piece step block and clamp set designed for workholding applications on milling machines and machining centers equipped with T-slot tables. The set uses 3/8-16 stud thread and fits 9/16-inch T-slots, making it compatible with a common T-slot size found on vertical mills and drill press tables. Step blocks measure 1 inch in width and are used in combination with serrated end clamps and studs to secure workpieces or fixtures during machining operations. Licensed machinists and toolroom technicians are the primary users of this set.

This set is suited for job shops, toolrooms, and production machining environments where versatile workholding is required. The six included stud lengths — 3, 4, 5, 6, 7, and 8 inches — allow the clamps to span a range of workpiece heights without requiring additional hardware. The set is appropriate for use on knee mills, Bridgeport-style machines, and similar equipment with 9/16-inch T-slot tables. It supports both light fixturing and more rigid clamping setups depending on stud and block configuration.

Key Features

• Six stud lengths (3, 4, 5, 6, 7, and 8 inches) provide flexibility across varied workpiece heights
• 1-inch step block width with serrated end clamps for positive grip on workpieces

Compatibility

Designed for use with milling machines and machining center T-slot tables with a 9/16-inch T-slot and 3/8-16 stud thread hardware.

Installation Notes

Installation is performed by machinists or toolroom personnel. Always power down and lock out the machine before positioning clamps or adjusting workholding setups on the table. Ensure studs are fully engaged in the T-slot nuts and that clamps are seated flat against the workpiece or step block before tightening. Follow your shop's workholding procedures and applicable safety standards when setting up for a machining operation.
