Product Description:
Stainless Steel Hexagonal Bar – Six-Sided Profile for Fastener & Precision Machining
Stainless steel hexagonal bars (hex bars) are long bars with a six-sided cross-section, manufactured from stainless steel billets through cold drawing or hot rolling processes. The hexagonal shape is specifically designed for manufacturing fasteners (bolts, nuts, set screws) and components that require wrenching surfaces. The across-flats dimension is the critical measurement for hex bars.
ASTM A276 is the primary standard covering cold-finished stainless steel hexagonal bars for general structural and mechanical applications. ASTM A479 is specified for pressure vessel applications. ASTM A484 governs dimensional tolerances.
Why choose hexagonal bars:
Fastener manufacturing – Hex bars reduce material waste when machining hexagonal heads
Automatic lathe friendly – Perfect for high-volume CNC screw machining
Easy wrenching – Six sides provide excellent grip for tools
Cost-effective – Less machining required compared to round bar for hex-shaped parts
Typical applications include:
Fasteners: Bolts, nuts, set screws, studs, threaded rods
Fittings: Pipe fittings, adapters, couplings
Valves: Valve stems, bonnet nuts, packing nuts
Hydraulics: Hydraulic fittings, adapters
General machining: Wrench components, tooling, custom parts
Automotive: Engine components, suspension parts
Marine: Boat hardware, deck fittings
