Through Bolts vs Dynabolts: Installation & Load Capacities – Order Direct from Newlands Fasteners

06 November 2025


Newlands Fasteners supplies high-quality fasteners engineered for durability and safety in demanding construction and engineering projects. Comparing through bolts vs dynabolts is essential to determine which option delivers the best performance for specific structural applications. We ensure our customers have access to the right anchors for secure, long-lasting results that meet strict safety and load-bearing standards.

What Are Through Bolts? Applications and Benefits

Through bolts are heavy-duty anchors designed for secure fixing into concrete and solid masonry. They deliver exceptional tensile and shear performance, making them ideal for structural connections under significant stress. Their straightforward design allows quick installation and reliable long-term stability.

These fasteners are widely used in industries such as construction, mining, and infrastructure development. They are chosen for heavy equipment installation, steel framework assembly, and bridge or tunnel projects where strength and safety are critical.

What Are Dynabolts? Features and Uses

Dynabolts or sleeve anchors are medium-duty expansion anchors with a sleeve that expands when tightened, creating a secure hold in masonry or concrete. They are well-suited for applications requiring moderate strength and are easy to install without specialised tools.

Builders, contractors, and facility managers rely on Expansion anchors for tasks such as installing handrails, shelving, HVAC brackets, and light machinery. They are a practical, cost-effective option for residential, commercial, and light industrial projects.

Load Capacities and Performance Comparison

Selecting between anchor bolts and dynabolts depends on performance needs and structural conditions. Below is a comparison to help determine the most suitable fastener for your project.

•  Tensile Strength: Structural bolts provide exceptional tensile strength, making them ideal for securing heavy structural components. Expansion anchors, while reliable, are better suited to moderate loads where extreme strength is not required.

•  Shear Strength: Through bolts excel under high shear forces and maintain stability in demanding conditions. Expansion anchors handle lighter forces effectively but are not designed for heavy-duty applications.

•  Vibration Resistance: Anchor bolts perform well under continuous vibration and dynamic stress. Dynabolts are suitable for static or low-movement fixtures where vibration is minimal.

•  Installation Speed: Dynabolts allow quick and simple installation without specialised tools. Anchor bolts take longer to install but deliver a more secure and permanent hold.

•  Application Suitability: Through bolts are preferred for infrastructure, mining, and industrial projects requiring maximum stability. Expansion anchors are a cost-effective option for residential and light commercial use.
