Three-part expanding shield anchor with projecting bolt for solid fixings in brick and concrete. The loose nut gives flexibility on fixture thickness, and the expanding shield compensates for slightly oversized holes caused by drilling in softer masonry.

Shield anchors with a projecting bolt are a straightforward, reliable fixing for brick, blockwork, and concrete. The three-part expanding shield grips the substrate as the bolt is tightened, pulling the shield open against the sides of the drilled hole. This gives a solid, load-bearing fixing that holds well even in slightly oversized holes — a common issue when drilling brick with a powerful hammer drill. These shield anchors with projecting bolt come in a range of sizes from M6 through to M16, covering most standard fixing requirements on site.
The projecting bolt design means the threaded section protrudes from the anchor body, allowing you to fix through materials of varying thickness. The loose nut gives additional flexibility, letting you adjust for different fixture thicknesses and hole depths without needing a separate bolt. That makes them particularly useful when you are fixing brackets, handrails, shelving supports, or structural frames where the exact depth or material thickness can vary slightly between fixings.
Where Shield Anchors Projecting Bolt Get Used
These anchors are a go-to fixing for trade jobs involving brick or concrete substrates. Because the three-part expanding shield spreads the load across a wider contact area than a single-piece anchor, they perform well in softer or more variable masonry where oversized holes are more likely. The loose nut design makes them quicker to use in practice, since you are not battling a fixed thread against an imperfect hole depth.
Sizing and Pack Options
Available in sizes from M6 x 10mm up to M16 x 35mm, with packs of 10 or 25 depending on the size. Selecting the right size comes down to the bolt diameter required by your fixture and the depth of embedment you need for the load. Heavier loads and larger fixtures naturally call for the larger M12 or M16 options, while M6 and M8 cover lighter brackets and fittings. Check the manufacturer’s load data for the substrate type before specifying on structural applications.
Pro Tip: When drilling into brick for these anchors, drill into the brick itself rather than the mortar joint, and use a sharp bit to keep the hole as clean as possible — a ragged or oversized hole still benefits from the three-part expanding shield, but a clean hole gives you the best pull-out resistance.
Shield anchors with projecting bolt are used across a wide range of trade applications in brick and concrete. Common jobs include fixing handrails, balustrading brackets, pipe clips, cable trays, shelving supports, and structural steel frames to masonry walls. They are widely used by building contractors, groundworkers, mechanical and electrical installers, and maintenance trades working on both new build and refurbishment projects.
The three-part expanding shield makes these anchors particularly suited to brick and medium-density blockwork where drilling conditions are variable. They are equally at home in dense concrete, where the tight hole tolerances make the expanding shield grip all the more firmly.

Not suitable for: Not suitable for use in hollow materials, cavity walls, or soft substrates such as aerated blocks without checking load ratings carefully. Not designed for dynamic or vibration-heavy load applications without engineering sign-off.
Drill a clean hole to the correct diameter and depth for the anchor size selected. Insert the shield anchor into the hole so the shield body sits flush with or just below the surface. Place your fixture over the projecting bolt, add the loose nut, and tighten down. As the nut is tightened, the bolt draws the expanding shield open against the walls of the hole, locking the anchor in place.
Ensure the hole depth matches the anchor length to allow full expansion of the shield. Avoid over-tightening, which can crack the masonry around the hole in softer brickwork. Always clear dust and debris from the hole before inserting the anchor.
Select the correct anchor size for your bolt diameter and the load requirements of the application.
Drill a clean hole to the specified diameter and depth using a hammer drill and correctly sized masonry bit.
Clear all dust and debris from the hole using a brush or compressed air.
Insert the shield anchor into the hole with the expanding shield end going in first.
Position your fixture over the projecting bolt.
Thread the loose nut onto the bolt by hand until it contacts the fixture.
Tighten the nut with a spanner to draw the bolt up and expand the shield against the hole walls.
Tighten to the recommended torque for the anchor size — avoid over-tightening in brick or softer masonry.
Can these shield anchors be used in brick as well as concrete?
Yes. Shield anchors with projecting bolt are designed for use in both brick and concrete. The three-part expanding shield is particularly useful in brick, where holes can end up slightly oversized due to the variable hardness of the material. The wider contact area of the three-part shield helps maintain grip even when the hole is not perfectly sized.
What does the loose nut do on a projecting bolt shield anchor?
The loose nut allows you to adjust for different fixture thicknesses and hole depths. Rather than being fixed at a set position, the nut can be threaded to where it needs to be on the bolt, giving you more flexibility when fixing materials of varying thickness or when hole depths are not perfectly consistent across multiple fixings.
How do I choose the right size shield anchor for my job?
Select the bolt diameter to match the fixing hole in your bracket or fixture, and choose the embedment depth based on the load requirements and the substrate. Heavier brackets, handrails, and structural fixings generally need M10, M12, or M16 anchors with a longer embedment, while lighter fittings such as pipe clips or cable trays are typically fine with M6 or M8. Check the load data for your specific substrate before specifying on structural applications.
Shield anchors with projecting bolt consist of a three-part expanding shield body and a projecting threaded bolt with loose nut. As the nut is tightened, the bolt pulls upward, forcing the segmented shield to expand radially against the drilled hole. This mechanical expansion creates a friction and form-locking grip in the substrate. Available in carbon steel construction, suitable for interior and sheltered exterior applications. Sizes range from M6 to M16 with varying embedment depths.
