If you're sourcing fasteners that guarantee mechanical reliability, compliance, and cost-efficiency, the AS 2451 BSW threaded hex head bolt is your go-to solution.
What Are AS 2451 BSW Threaded Hex Head Bolts?
AS 2451 BSW threaded hex head bolts are externally threaded fasteners that feature a hexagonal head for wrench tightening, combined with a coarse-thread profile based on the British Standard Whitworth (BSW) system. These bolts are manufactured in compliance with AS 2451, the Australian standard governing hex bolts, ensuring consistent thread pitch, tensile strength, and head dimensions.
Whether you're in mining, construction, heavy machinery, or structural engineering, AS 2451 BSW threaded hex head bolts deliver unmatched fastening performance under extreme load and vibration conditions.
Why Choose AS 2451 BSW Threaded Hex Head Bolts?
1. Standards-Compliant Manufacturing
All AS 2451 BSW threaded hex head bolts are manufactured to rigorous Australian Standard AS 2451 specifications. This ensures exacting thread tolerances, dimensional uniformity, and consistent mechanical strength — critical for high-performance assembly operations.
2. Superior Thread Holding Power
The BSW thread form offers a deeper and more rounded thread profile compared to metric threads. This provides enhanced load-bearing surface area, making AS 2451 BSW threaded hex head bolts ideal for applications where strong grip and resistance to loosening under vibration are essential.
3. Durable and Corrosion-Resistant
Available in a variety of coatings such as hot-dip galvanized, black oxide, and zinc-plated finishes, AS 2451 BSW threaded hex head bolts provide long-term durability and corrosion resistance — even in outdoor and marine environments.
4. Versatile Across Industries
From mining equipment and construction frameworks to machinery assembly and infrastructure projects, AS 2451 BSW threaded hex head bolts are a preferred choice among engineers and procurement professionals worldwide.
5. Fast Installation and Easy Maintenance
The hex head design allows for quick tightening and loosening using standard wrenches and sockets, saving time during assembly and maintenance.
