This is a 6-inch (150 mm) stainless steel rule with a wide 50 mm blade designed for accurate linear measurement and marking in workshops, on-site jobs and general-purpose toolbox use. Its primary use is to give a compact, stable measuring edge for engineers, machinists, joiners and tradespeople who need a short, rigid rule for setting out, checking dimensions and marking materials in both metric and imperial units.

The blade is manufactured from stainless steel EN 1.4301 (AISI 304) with a satin, passivated finish to resist staining and surface corrosion. The rule carries dual graduations in millimetres and inches; graduations are laser-etched and contrast-filled for long-lasting legibility and conformity with recognised workshop measuring conventions (metric divisions to 1 mm with clear inch fractions). The 50 mm width gives extra stiffness compared with narrow pocket rules, helping to reduce deflection when scribing or transferring measurements. Edge straightness and marking accuracy are suitable for routine workshop tolerances.

Typical applications include setting out and checking components in metal fabrication, marking timber and sheet materials in joinery, quick verification of small parts in maintenance and assembly, electrical and plumbing installations, and use by instrument makers and hobby engineers. The compact length makes it convenient for inspectors, service engineers and on-site trades where a larger rule would be impractical.

Key benefits are corrosion resistance from the stainless construction, stable behaviour provided by the wide blade and durable, easy-to-read graduations that remain visible under heavy use. The rule is compatible with commonly used measuring practices and can be used alongside callipers, squares and spirit levels without introducing scale mismatch. Its size balances portability with sufficient length for everyday measuring tasks.

Duchy Fasteners stocks this stainless steel rule in single items and multi-packs, and we also offer longer steel rules (300 mm, 600 mm and 1 m) and alternative widths to suit workshop and site requirements. If you need a particular pack quantity or length, please contact us for availability.
