Steel round bar bright mild steel round bar rod EN3B x 300mm 11.8" 5/8" 15.87mm Dia 230M07 070M20

This 5/8 inch (15.87mm) bright mild steel round bar is a slender, versatile engineering stock supplied to EN3B specification and cut to 300mm (11.8 inch) in length. The 5/8 inch size is a classic imperial dimension widely used in older British and American machinery, making this bar ideal for replacement shafts, pivot pins, and linkage rods where imperial sizing is required. The bright drawn finish ensures a clean, smooth surface with tight dimensional accuracy — ready to use straight from the bar or with minimal turning. Also referenced under 230M07 and 070M20 specifications, covering both free-cutting and standard mild steel grades at this diameter. Weldable, machinable, and suitable for a wide range of general fabrication and engineering applications.
