Mitutoyo 182-142 Steel Rule 18 in 16R Rigid

Product Description

The MITUTOYO 182-142 is a rigid stainless steel rule designed for precise linear measurement in trade and industrial applications. Finished in satin chrome plating, it measures 18 inches in overall length and 1-3/16 inches in width, with a thickness of 0.05 inches. The rule carries 16R graduation style with four graduation increments: 1/100, 1/32, 1/50, and 1/64 inch. These combined scales allow machinists, pipefitters, fabricators, and layout technicians to read fractional and decimal measurements from a single tool without switching rules.

This rule is suited for bench work, layout, and inspection tasks in machine shops, fabrication shops, plumbing rough-in, and HVAC duct layout. The rigid construction prevents deflection during scribing or part comparison. The satin chrome finish reduces glare under shop lighting, improving graduation readability. It is a horizontal-scale rule and does not include a hook. It is not magnetic, making it appropriate for use near sensitive components where magnetic rules are undesirable.

Key Features

• Four graduation increments on a single rule: 1/100, 1/32, 1/50, and 1/64 inch
• 16R graduation style for versatile fractional and decimal reading
• Rigid stainless steel construction resists flex and corrosion
• Satin chrome plating reduces glare and improves scale contrast
• 18-inch overall length covers common layout and cut-line tasks
• Non-magnetic design suitable for use near electronic or magnetic-sensitive components

Compatibility

Designed as a general-purpose rigid steel rule for use in machining, fabrication, plumbing layout, HVAC duct work, and similar trade measurement applications.

Installation Notes

No installation is required for this measuring tool. Store the rule flat or in a protective sleeve to prevent edge damage and maintain graduation legibility. Avoid using the rule as a prying or cutting guide, as edge damage will compromise measurement accuracy. Calibration verification against a traceable reference standard is recommended when the rule is used for inspection or quality-control purposes.
