Bolts for construction and machinery designed to deliver secure, vibration-resistant fastening, ideal for heavy-duty assemblies with reliable performance using TA-VIGOR Flanged Hex Bolts. Tradespeople and experienced DIYers gain confidence from durable, high-strength fasteners on structural work. Are these the heavy-duty fixings worth choosing for long-term builds?
⚡ At a Glance
- • Holding Strength: 10.9 grade carbon steel construction for high tensile load-bearing performance
- • Best for: Tradespeople, engineers and DIYers assembling steel structures and machinery
- • Not ideal for: Applications that require stainless or non-ferrous fasteners
Fully threaded M10 x 30mm with 1.5mm pitch, serrated hex flange and black oxide finish. Designed for heavy-duty fastening in structural, automotive and industrial contexts.
Vibration-resistant joints - with serrated hex flange
Serrations under the flanged head bite into mating surfaces and increase friction, resisting rotation under repeated vibration and torque. The hex head allows secure wrench engagement for correct torque application.
Reduced risk of loosening during machine operation or transport, keeping bolted assemblies secure without frequent retightening.
High load capability - with 10.9 grade carbon steel
Heat-treated 10.9 grade carbon steel delivers higher tensile strength and improved yield performance compared with lower grades. Black oxide finish adds a thin protective layer to help resist corrosion.
Suitable for structural connections and heavy machinery where strong, dependable fasteners are required for long-term load-bearing.
Simple installation and strong clamping - with fully threaded M10 x 30mm shaft
Fully threaded shaft with a 1.5mm metric pitch allows engagement along the entire length of the bolt for adjustable clamping. Flanged head spreads load across the contact surface, reducing the need for separate washers in many applications.
Faster assembly and straightforward replacements on-site, with even load distribution that helps protect joined materials.
