Fowler 52-426-002-0 Tool Steel Square 2.375in Blade

Product Description

The FOWLER 52-426-002-0 is a precision tool steel square designed for accurate right-angle layout and measurement work. With a blade length of 2.375 inches and a base length of 1.375 inches, this compact square delivers an accuracy of 0.0001 inches (0.000104 inches decimal), making it suitable for fine machining, toolmaking, and inspection tasks. The matte finish reduces glare in workshop lighting conditions. The beveled edge design allows the blade to seat flush against a workpiece for precise scribe lines and angle verification. Machinists, toolmakers, and metrologists rely on this type of square for layout tasks where standard squares lack the necessary accuracy tolerance.

This square is intended for layout and measurement work across a range of trade and precision manufacturing applications. Its compact size makes it well-suited for close-tolerance inspection on small parts, bench work, and die or mold setup. The tool steel construction resists wear and maintains dimensional stability under typical shop conditions. It is appropriate for use in machine shops, tool rooms, and quality control environments where repeatable right-angle references are required.

Key Features

• Accuracy of 0.0001 inches for close-tolerance layout and inspection
• Beveled edge blade seats flush against workpiece surfaces for precise scribing
• Tool steel construction provides durability and dimensional stability
• Matte finish reduces glare under shop lighting
• Compact form factor suited for small-part and bench work applications

Compatibility

Designed for general layout and measurement work; compatible with standard precision layout and inspection workflows in machine shops, tool rooms, and quality control environments.

Installation Notes

This is a hand-held precision measurement tool and does not require mechanical installation. Handle with clean, dry hands or lint-free gloves to prevent corrosion from skin oils. Store in a protective case or dedicated tool drawer away from abrasive materials to preserve the reference surfaces and accuracy. Periodically verify squareness against a known reference standard as part of routine tool calibration practice.
