Spi 14-688-6 Flexible Steel Rule 24 Inch Decimal Metric

Product Description

The SPI 14-688-6 is a flexible steel rule measuring 24 inches in overall length and 3/4 inches in overall width. Finished with a satin chrome-plated coating for glare reduction and corrosion resistance, this rule is designed for precision layout and measurement in machine shops, fabrication environments, and tool rooms. It carries both decimal and metric graduations, with inch graduations at 1/100 and 1/2 increments, making it suitable for applications requiring fine resolution or quick reference. The flexible construction allows the rule to conform to curved surfaces where a rigid rule would produce inaccurate readings. At 0.0200 inches thick and weighing 1 pound, it is a durable everyday layout tool.

This rule is appropriate for machinists, tool and die makers, fabricators, and quality control technicians working in both imperial and metric measurement environments. The horizontal scale orientation and dual graduation styles support a wide range of measurement tasks, from rough layout to fine dimensional verification. It is equally suited to bench work and field measurement on light fabrication projects.

Key Features

• Flexible construction conforms to curved or contoured surfaces for accurate readings
• Dual graduation system: decimal inch (1/100) and metric, with 1/2 inch reference marks
• Satin chrome-plated finish reduces glare and resists corrosion
• 24 inches overall length with 3/4 inch width for easy handling and readability
• Horizontal scale orientation for consistent left-to-right measurement
• No hook or magnetic features — straightforward, lightweight layout rule

Compatibility

Designed as a general-purpose flexible steel rule for machine shop, fabrication, and inspection use where both decimal inch and metric graduations are required.

Installation Notes

No installation is required for this hand tool. Store flat or rolled loosely to avoid permanent bends that could affect accuracy. Wipe clean after use to prevent buildup on the graduated surface. Inspect graduations periodically for wear, particularly in high-use shop environments.
