Concrete screws/Anchors Thunder Bolt (HSPC20)

Maximize your structural efficiency with the Thunderbolt range of concrete screws and anchors, the original high-performance masonry fixing.¹ Engineered for speed, reliability, and immense load-bearing capacity, Thunderbolts have revolutionized the way professionals approach heavy-duty anchoring in concrete, brick, stone, and block.

Why Choose Thunderbolt Concrete Screws?

The Thunderbolt is a self-tapping masonry anchor that creates its own thread during installation.² Unlike traditional expansion anchors, it does not exert outward pressure on the substrate, making it the ideal solution for close-to-edge applications and reducing the risk of cracking the base material.³

Key Features & Benefits

• Mechanical Galvanized & Zinc Plated Options: Available in various finishes to provide superior corrosion resistance for both internal and external projects.⁴

   

• All-Steel Construction: Provides exceptional tensile strength and fire resistance compared to plastic-sleeved alternatives.⁵

   

• Non-Expansion Fixing: Allows for closer spacing between anchors and prevents stress on the concrete or masonry.⁶

   

• Fast Installation: Simply drill a pilot hole and drive the screw in—no need for resin, toggles, or specialized setting tools.

• Fully Removable: Perfect for temporary fixtures or site adjustments, leaving a clean hole behind.⁷

   

Technical Specifications & Versatility

Whether you are securing timber wall plates, steel trunking, or heavy machinery, the Thunderbolt range offers a diameter and length for every requirement.

Installation Guide: How to Fit a Thunderbolt

To ensure maximum pull-out resistance and structural integrity, follow these essential steps:

1. Drill: Use a masonry bit of the same diameter as the Thunderbolt (e.g., use an 8mm bit for an 8mm bolt).

2. Clean: Remove all dust and debris from the hole using a blow pump or vacuum.⁸

    

3. Drive: Use a socket wrench or impact driver to screw the Thunderbolt directly into the hole.

4. Secure: The threads will tap into the masonry, creating a secure, mechanical interlock.⁹

    

Applications in Construction

The Thunderbolt range is the go-to choice for contractors across multiple sectors:

• Fencing & Railings: Secure posts to concrete pads with confidence.

• HVAC & M&E: Mounting brackets and pipework to ceilings and walls.

• Carpentry: Attaching sole plates and timber frames to foundations.

• Warehouse Fit-outs: Bolting racking and shelving to industrial floors.

Looking for the toughest fix on the market? The Thunderbolt range provides the "drill, drive, done" efficiency that modern construction demands.
