Spi 13-868-5 Flexible Steel Rule 12 in 16R Graduation

Product Description

The SPI 13-868-5 is a flexible steel rule designed for precision layout and measurement work in trade and industrial settings. Measuring 12 inches in overall length and 0.5 inches wide, this rule features 16R graduation style with four scales: 1/100, 1/32, 1/50, and 1/64 inch. The blade is finished in satin chrome plating for glare reduction and corrosion resistance. At 0.020 inches thick, the flexible construction allows the rule to conform to curved or irregular surfaces. Machinists, pipefitters, sheet metal workers, and fabricators use this type of rule for close-tolerance layout and inspection tasks.

This rule is suited for use in machine shops, fabrication shops, plumbing, HVAC, and general mechanical trades wherever fine fractional and decimal inch measurements are required. The horizontal scale orientation and four-graduation 16R layout make it practical for tasks that require reading both fractional and decimal inch increments from the same blade. The satin chrome finish reduces reflective glare under shop lighting, improving readability during layout work.

Key Features

• Four graduation scales: 1/100, 1/32, 1/50, and 1/64 inch on a single blade
• 16R graduation style with horizontal scale orientation
• Flexible blade conforms to curved or uneven surfaces
• Satin chrome-plated steel construction resists corrosion and reduces glare
• 0.020-inch blade thickness for use in confined measurement areas
• No hook or magnetic features — clean, standard rule format

Compatibility

General-purpose flexible steel rule suitable for use in machine shop, fabrication, plumbing, HVAC, and sheet metal trade applications requiring 12-inch fractional and decimal inch measurement.

Installation Notes

No installation is required for this hand tool. Store the rule flat or in a protective sleeve to prevent blade distortion and scale wear. Avoid exposing the chrome-plated surface to harsh solvents or abrasive materials that may degrade the finish and reduce scale legibility. Inspect graduations periodically for wear in high-use environments.
