Concrete Fixing Bolts 12 x 100mm (Box of 25)

12mm x 100mm Timco Concrete Fixing Bolts – Hex Head Thunderbolt Fixings

Our 12mm x 100mm Timco Concrete Fixing Bolts are a high-performance, non-expansion through fixing designed for heavy-duty anchoring into concrete, brick, stone, wood, and concrete block. Engineered to provide a fast, reliable, and stress-free installation, these advanced fixings offer an effective alternative to traditional anchoring systems such as throughbolts, shield anchors, sleeve anchors, and drop-in anchors.

Featuring a unique high-low parallel thread design and concave thread configuration, these concrete fixing bolts provide excellent pull-out performance while ensuring easy insertion and reduced installation effort. Their non-expansion design minimises stress on the base material, making them particularly suitable for applications where edge distances and spacing are critical.

Manufactured using Timco Nano Technology Micro Plating, these fixings deliver enhanced corrosion resistance and long-lasting performance in urban and industrial environments. They are also fully removable and adjustable after installation, providing greater flexibility than many traditional anchoring methods.

As an all-steel, non-flammable fixing, these concrete bolts conform to the requirements of BS 7671 18th Edition, which specifies that wiring systems should be supported by materials unlikely to collapse prematurely in the event of a fire.

Supplied for professional construction, electrical, mechanical, and industrial applications, these versatile fixings are ideal for securing structural components, brackets, framework, cable management systems, and heavy-duty fixtures.
