Starrett 51375 Flexible Steel Rule 12 in 16R

Product Description

The STARRETT 51375 is a flexible steel rule designed for precision measurement in trade and industrial applications. The rule measures 12 inches in overall length and 0.5 inches in overall width, with a satin chrome-plated finish that reduces glare and resists corrosion. At 0.020 inches thick, the blade flexes to conform to curved or irregular surfaces without sacrificing readability. The 16R graduation style provides four scales in a single rule: 1/32, 1/64, 1/50, and 1/100 inch increments. This combination makes it a practical tool for machinists, pipefitters, HVAC technicians, and sheet metal workers who need fine-resolution measurements on the job.

The 51375 fits standard layout and inspection tasks in both shop and field environments. Its horizontal scale orientation and compact 0.5-inch width allow it to fit into tight spaces where wider rules cannot reach. The satin chrome finish keeps markings legible under shop lighting. The rule ships individually and is suited for toolbox carry or bench use. It does not include a hook and is not magnetic, keeping it simple and lightweight at 0.063 pounds.

Installation Notes

No installation is required for this hand tool. Store the rule flat or in a protective sleeve to prevent blade distortion over time. Avoid using the rule as a straightedge for scoring or cutting, as this can damage the graduation markings. Clean with a dry cloth after use to maintain the chrome-plated finish.
