## Overview

The Thunder D-Bolt Anchor 8-pack features M8 x 100 mm self-tapping bolts with a hexagonal head, engineered for heavy-duty masonry anchoring. Crafted from high-grade alloy steel with a yellow zinc finish, these anchors provide a stress-free, non-expansion fix into concrete, brick, stone, and wood. Their unique dual thread design allows rapid installation, easy removal, and refixing, making them the go-to solution for professional-grade, versatile, and durable anchoring.

## Description

Simply drill a hole using the correct masonry drill bit, remove the dust and debris and wind in. No need for plastic plugs. These bolts are classed as non-expansion anchors which means they won't stress the concrete when fixing. The unique concave thread design taps its own thread and provides a rapid, low torque installation with exceptional pull out resistance. It also allows the user to adjust or remove the bolt ensuring a secure and accurate installation. This stress free, non-expansion through fixing is the new solution for medium duty anchoring into concrete, brick, stone, wood and concrete block replacing the need for traditional anchors such as through bolts, shield, sleeve and drop-in anchors. Always 'over drill' the hole by 20mm.

## Features

- FEATURES: New solution for heavy duty anchoring. Anchor bolts are designed for many masonry surfaces in providing a mechanical interlock between construction material and the fixing, close to edge fixing with no expansion stress.
- QUALITY: Hex head allows close to edge fixings alongside a dual thread that ensures correct alignment of anchor. Thread pitch allows bolt to anchor without the need of fixtures. Concrete fixing bolts are self-tapping allowing full removal of bolt and refixed into same hole with ease.
- FINISH: Constructed from high grade steel with a yellow zinc finish
- APPLICATION: Anchor bolts are multipurpose in fixing handrails, post supports, timber battens and satellite dishes. Ideal for surfaces and materials of concrete, brick, timber, marble, concrete block and stone.
