EN8, per BS970:1955, is a medium carbon steel known for its balance of strength, toughness, and machinability. When processed into cold drawn bright hexagonal bars, EN8 becomes even more suitable for precision-machined parts with enhanced surface finish and tighter dimensional control.
At Steelmet Industries, we offer EN8 Cold Drawn Bright Hexagon Bars in across-flat (A/F) sizes ranging from 12.7mm to 65mm, with precise tolerances and consistent mechanical properties—ideal for tools, fasteners, shafts, and engineering assemblies that require both strength and aesthetics.

Frequently Asked Questions – EN8 Bright Hex Bars
Q1: What does “cold drawn bright hexagon” mean?
A: Cold drawing is a process of pulling hot-rolled bars through a die, improving dimensional accuracy, surface finish, and mechanical strength. The “bright” finish is clean, polished, and free of scale.
Q2: What tolerance do EN8 cold drawn hex bars maintain?
A: Tolerances as per IS, DIN, or customer-specified norms are achievable—typically h11 or tighter based on requirements.
Q3: Can I order custom cut-to-length bars?
A: Yes. Steelmet offers custom cutting services to minimize scrap and optimize productivity at your end.
Q4: Are these bars weldable?
A: Yes, though EN8 has medium carbon content. Pre-heating and post-weld stress relief are recommended.
Q5: What packaging options are available?
A: Bars are supplied in bundled form with steel straps, ID tags, and optional bar coding or plastic wrapping as per agreement.
