RS PRO Flat Tool Steel Steel Bar, 20mm Width, 5mm Height, 500mm Length, Tensile Strength 540MPa 682-129

RS PRO 682-129 Flat Tool Steel Steel Bar is a high-grade engineering material designed for precision applications requiring high tensile strength of 540MPa. This flat steel bar measures 20mm in width, 5mm in height, and 500mm in length, making it suitable for varied industrial and manufacturing uses where dimensional stability and surface quality are critical.

Manufactured from fully annealed tool steel that is free from carburisation, this bar is precision ground to close tolerances, enabling the production of finished components with minimal additional machining. It conforms strictly to BS4659: 1971 BO1 standards, ensuring a reliable and consistent product quality.

The flat tool steel bar offers excellent hardening capabilities combined with superior resistance to wear, making it ideal for jigs, dies, cams, machine parts, punches, templates, and gauges found in industrial, mechanical, and manufacturing settings.

Precision tolerance metrics include imperial width tolerance of -0.000 +0.005 inches and thickness tolerance of -0.001 +0.001 inches, with metric equivalents of -0.000 +0.127mm width and -0.000 +0.050mm thickness. These tight tolerances guarantee engineering precision for complex tooling and fabrication processes.

Originating from the United Kingdom, this tool steel bar reflects premium manufacturing standards and is widely used across industrial workshops, fabrication shops, and production lines requiring tool steel in flat bar form.
