Spi 30-155-6 Flexible Steel Rule 6 Inch 16R

Product Description

The SPI 30-155-6 is a flexible 6-inch steel rule finished in satin chrome plating for glare reduction and corrosion resistance. Designed for layout, inspection, and measurement tasks in trade and industrial settings, this rule features a 16R graduation pattern that includes four scales: 1/32, 1/64, 1/100, and 1/50 inch. The flexible construction allows the rule to conform to curved or irregular surfaces where a rigid blade would produce reading errors. At 0.015 inches thick and 0.5 inches wide, it fits into tight spaces without sacrificing scale legibility. Machinists, pipefitters, fabricators, and toolroom technicians are the primary users of this type of precision rule.

The 30-155-6 is suited for bench measurement, scribe layout, and field inspection work in metal fabrication shops, mechanical contracting, and precision manufacturing environments. The 6-inch overall length makes it a compact carry rule for technicians who need quick fractional and decimal inch readings without pulling a full-size blade. The 16R graduation style is a standard format widely used in machining and HVAC sheet metal layout, providing both common fractional and fine decimal inch divisions on a single blade.

Key Features

• Flexible blade conforms to curved and irregular surfaces for accurate contact measurement
• 16R graduation includes four scales: 1/32, 1/64, 1/100, and 1/50 inch
• Satin chrome-plated finish reduces glare and resists corrosion
• Compact 6-inch overall length suits toolbox carry and tight-space use
• Thin 0.015-inch blade profile fits narrow slots and recessed areas
• No hook, non-magnetic construction for straightforward layout use

Compatibility

Designed as a standard 6-inch flexible steel rule for use in general precision measurement and layout applications across machining, fabrication, and mechanical trade work.

Installation Notes

No installation is required for this measuring tool. Store the rule flat or in a protective sleeve to prevent blade warping and finish wear. Avoid using the blade as a prying tool, as this can permanently deform the flexible steel and compromise measurement accuracy. Clean with a dry cloth after use to preserve the satin chrome finish.
