Stainless Steel Hexagon Bar

Stainless Steel Hexagon Bar: Common Specifications and Size Standards

Stainless steel hexagon bar (also called hex bar or hexagonal stainless steel rod) is widely used in machining, fastener production, mechanical components, and engineering structures. Its six-sided geometry provides excellent grip for machining operations and is ideal for bolts, kacang, and precision parts manufacturing.

The most important factor when selecting stainless steel hex bars is understanding the standard size range, across flats (AF) dimensi, and length tolerances used in industrial supply.


Common Size Range of Stainless Steel Hexagon Bar

Stainless steel hex bars are typically defined by the distance across flats (AF), which determines the bar’s size and application suitability.

Kategori Saiz Across Flats (AF) Equivalent Use
Small Hex Bar 3mm - 10 mm Precision screws, small fasteners
Medium Hex Bar 10mm – 30mm General machining parts, bolts
Large Hex Bar 30mm – 80mm Heavy-duty mechanical components
Extra Large Hex Bar 80mm – 120mm+ Industrial structural parts

Standard Length Specifications

Hexagon bars are commonly supplied in standard lengths suitable for machining and industrial fabrication.

  • Standard length: 3 meter
  • Standard length: 4 meter
  • Standard length: 6 meter
  • Custom cutting available according to requirements

Dimensional Tolerance and Precision Grades

Different manufacturing processes provide different levels of precision depending on application requirements.

Processing Type Tolerance Grade Kualiti Permukaan
Hot Rolled Hex Bar Standard tolerance (±0.5mm to ±1mm) Permukaan kasar
Cold Drawn Hex Bar Ketepatan tinggi (h9 / h11) Permukaan licin
Bright Hex Bar Very high precision Kemasan yang digilap

Common Stainless Steel Grades for Hex Bars

Hexagon bars are available in different stainless steel grades depending on corrosion resistance and mechanical requirements.

  • 304 / 304L – General-purpose corrosion resistance and machining
  • 316 / 316L – Persekitaran marin dan kimia
  • 303 – Improved machinability for fastener production
  • 410 / 420 – High hardness and wear resistance
  • 17-4PH – High-strength precision engineering applications

Pilihan Penamat Permukaan

  • Hot rolled black surface – structural and heavy-duty use
  • Permukaan jeruk - rintangan kakisan yang lebih baik
  • Bright drawn finish – precision machining applications
  • Polished surface – decorative or sanitary use
