Mitee-bite 33140 Locating Positioning Rail 3 Hole 1/4-20

Product Description

The MITEE-BITE 33140 is a 3-hole locating and positioning rail designed for precision workholding and fixture applications in machining environments. Manufactured from low carbon steel, this rail measures 4 inches in length, 0.48 inches in width, and 0.35 inches in height. It accepts 1/4-20 threaded fasteners across its three mounting holes, allowing rigid and repeatable part location on machine tables, jigs, and modular fixturing systems. An optional tungsten carbide coating can be applied to the rail surface to increase holding force in high-demand cutting operations. Machinists and toolmakers working with milling, boring, or precision grinding setups will find this rail a straightforward component for consistent workpiece positioning.

This rail is suited for use in both manual and CNC machining setups where accurate, repeatable part location is required. It is commonly integrated into modular fixturing grids, custom jig plates, and tombstone-style workholding systems. Its compact profile allows installation in tight fixture layouts without interfering with toolpaths or adjacent clamps. The 1/4-20 thread size is a widely used standard in light to medium-duty fixturing applications across job shops and production environments.

Key Features

• Low carbon steel construction provides durability in typical machine shop conditions
• Three mounting holes with 1/4-20 thread size for secure, adjustable positioning
• Compact profile at 4 inches long, 0.48 inches wide, and 0.35 inches high fits tight fixture layouts
• Optional tungsten carbide coating available to increase surface holding force
• Single-piece package quantity suitable for individual fixture builds or replacement needs

Compatibility

Designed as an OEM-style component for modular workholding and fixturing systems that use 1/4-20 threaded locating hardware.

Installation Notes

Installation is performed by qualified machinists or toolmakers using standard hand tools appropriate for 1/4-20 fasteners. Ensure the mounting surface is clean and flat before securing the rail to prevent misalignment. Deburr mounting holes and verify thread engagement before applying clamping loads. If the optional tungsten carbide coating is specified, handle the rail surface carefully to avoid chipping the coating prior to installation.
