Fowler 52-465-015-0 Parallel Clamp 3 in 4 in Jaw

Product Description

The FOWLER 52-465-015-0 is a parallel clamp designed for precision workholding in inspection, metrology, and machining setups. It uses a squeeze clamping action to hold workpieces with consistent parallel jaw alignment, reducing the risk of part movement during measurement or light machining operations. The jaws measure 4 inches in length and the clamp opens to a maximum capacity of 3 inches. Arm construction is hardened steel for durability under repeated use. The 10-32 thread size is standard for integration with fixture plates and surface plate accessories commonly used in quality control environments.

This parallel clamp is suited for use on surface plates, CMM fixtures, sine plates, and inspection setups where workpiece orientation and stability are critical. It is typically used by metrology technicians, tool and die makers, and precision machinists. The 4-inch throat depth allows the clamp to reach over workpiece features without interference, making it practical for holding parts with raised or irregular profiles during layout and inspection work.

Key Features

• Parallel jaw alignment maintains consistent clamping pressure across the workpiece surface
• Squeeze clamping action for quick and repeatable workholding
• 3-inch maximum capacity accommodates a wide range of part sizes
• 4-inch jaw length distributes clamping force over a larger contact area
• Hardened steel arms resist wear and deflection under repeated use
• 10-32 thread size is compatible with standard fixture plate configurations

Compatibility

Designed as an OEM-style parallel clamp for use with standard metrology fixture systems and surface plate setups requiring 10-32 threaded clamping components.

Installation Notes

Installation and setup should be performed by qualified metrology or machining personnel familiar with workholding practices. Before securing a workpiece, verify that the clamping surfaces are clean and free of debris to ensure accurate jaw contact. Do not overtighten beyond the design capacity of the clamp threads, as this can damage the 10-32 thread engagement. Follow your facility safety procedures and any applicable workholding standards when setting up inspection or machining fixtures.
