Spi 30-154-9 Flexible Steel Rule 6 Inch 5R

Product Description

The SPI 30-154-9 is a 6-inch flexible steel rule designed for precise linear measurement in layout, machining, and inspection tasks. Built from steel with a satin chrome-plated finish, it resists glare and corrosion during repeated shop use. The rule carries 5R graduation style, offering three graduation increments: 1/100, 1/32, and 1/64 inch. At 0.015 inches thick and 0.5 inches wide, it is slim enough to seat flush against workpiece edges or reach into shallow slots. Machinists, tool-and-die technicians, fabricators, and quality-control inspectors rely on this type of rule for quick, accurate measurements where rigid rules are impractical.

This flexible rule is suited for both shop floor and bench use in metalworking, manufacturing, and general trade applications. Its flexibility allows it to conform lightly to curved or irregular surfaces where a rigid rule would gap and produce inaccurate readings. The 5R graduation layout keeps multiple increment scales on one face, reducing the need to swap rules during layout work. It does not include a hook and is non-magnetic, making it appropriate for use near sensitive components or in environments where magnetism is a concern.

Key Features

• Flexible construction conforms to curved or irregular surfaces for accurate measurement
• 5R graduation style with 1/100, 1/32, and 1/64 inch increments on a single rule
• Satin chrome-plated finish reduces glare and provides corrosion resistance
• Slim profile at 0.015 inches thick and 0.5 inches wide seats flush against workpiece edges
• Non-magnetic and hook-free design suits sensitive or specialty measurement environments

Compatibility

Designed as a general-purpose flexible steel rule for metalworking, machining, fabrication, and inspection applications where a 6-inch flexible rule with 5R graduation is required.

Installation Notes

No installation is required for this measuring rule. Store flat or in a protective sleeve to prevent bending beyond the intended flex range, which could affect graduation accuracy. Clean the rule surface before use to ensure graduation markings are clearly legible. Handle with care to avoid kinking, as permanent deformation will compromise measurement accuracy.
