Spi 13-908-9 Steel Rule 24 Inch 16R Rigid

Product Description

The SPI 13-908-9 is a rigid steel rule measuring 24 inches in overall length and 1-1/8 inches in overall width. Black chrome-plated for durability and contrast readability, this rule carries a 16R graduation style with four scales: 1/32, 1/64, 1/100, and 1/50 inch. The horizontal scale orientation makes it well suited for layout, inspection, and fabrication tasks. At 0.0400 inches thick, the rule maintains a flat, rigid profile that holds position during measurement without flexing. Machinists, tool-and-die workers, fabricators, and quality technicians rely on this type of precision rule as a fundamental bench and layout instrument.

This rule fits standard trade and industrial applications including machine shop layout, sheet metal fabrication, welding fixture setup, and general dimensional inspection. The 16R graduation pattern provides both fractional and decimal inch scales on a single rule, reducing the need to switch between measuring tools during close-tolerance work. The rigid construction is preferred in applications where a flexible rule would introduce measurement error.

Key Features

• 24-inch overall length with 1-1/8-inch width for wide, stable reference surface
• 16R graduation style includes 1/32, 1/64, 1/100, and 1/50 inch scales
• Rigid construction holds flat profile for accurate layout and inspection work
• Black chrome-plated finish improves contrast and resists corrosion
• Horizontal scale orientation for consistent left-to-right reading
• No hook, non-magnetic — straightforward layout and bench use

Compatibility

Designed as a general-purpose precision steel rule for machinists, fabricators, and inspection professionals requiring 16R fractional and decimal inch graduations on a rigid 24-inch blade.

Installation Notes

No installation is required for this hand tool. Store the rule flat or in a protective sleeve to prevent edge damage and maintain graduation legibility. Clean the blade with a dry or lightly oiled cloth to prevent surface oxidation. Handle the rule by its body rather than dragging it across abrasive surfaces to preserve the black chrome finish.
