DTS Multi-Fix Anchor Bolt Hex Head Concrete Masonry Wood

The DTS Multi-Fix Anchor Bolt is a non-expansion through-fixing designed for heavy-duty anchoring into concrete, brick, stone, masonry block and timber. Where traditional expansion anchors create stress in the substrate as they expand, this anchor bolt works differently. The unique concave high-low thread configuration bites into the base material on insertion without any outward force, making it a genuine alternative to throughbolts, shield anchors, sleeve anchors and drop-in anchors for most common fixing applications.

Available in diameters from 6mm to 12mm and lengths from 50mm to 200mm, the DTS Multi-Fix Anchor Bolt covers a wide range of structural and general fixing tasks across the trades. The bolt is sized to the drill bit, so an 8 x 60mm bolt requires an 8mm drill. No guesswork, no adapters, no wasted trips back to the van.

What Sets the DTS Multi-Fix Anchor Bolt Apart

Conventional expansion anchors work by spreading outward against the material they sit in. That outward pressure is what gives them grip, but it also creates stress in the surrounding substrate, which can be a problem in older brickwork, near edges, or in materials that are less predictable. This anchor bolt avoids that issue entirely. Because it is a non-expansion fixing, it does not stress the host material during installation. That makes it well suited to situations where edge distances are tight or the substrate needs careful treatment.

The high-low parallel thread design serves two purposes. The high threads bite deeply into the drilled hole to deliver strong pull-out resistance. The low threads allow smooth, controlled insertion without the bolt binding or jamming partway down. On a busy site where you are driving dozens of fixings in a day, that difference in feel and speed is genuinely noticeable.

The hex head makes installation straightforward with a standard socket set or impact driver. No specialist tooling is required. Once in place, the bolt is fully removable and adjustable, which is useful when you need to reposition a bracket, realign a frame, or take apart a structure without destroying the fixing point. Traditional anchors are generally one-and-done, so this is a practical advantage for any fixing that might need to come out at a later date.

Box Quantities and Sizing

The DTS Multi-Fix Anchor Bolt is sold in boxes of 25, 50 or 100 depending on the size selected, which suits both small jobs and bulk fixing work. The bolt diameter matches the drill size directly, so specifying and ordering is simple. Whether you are setting out a concrete floor fixing at 12 x 150mm or a light timber application at 6 x 50mm, the same principle applies across the full range.

For trades who want a single anchor bolt that works reliably across different materials without carrying multiple fixing types, the DTS Multi-Fix is a practical, straightforward choice.
