Masonry frame fixing screws are the straightforward solution for anchoring frames directly into masonry without plugs, without pre-marking, and without the back-and-forth of separate fixings. These 7.5mm concrete frame screws let you drill and fix in one operation, which on a busy install day adds up to a serious time saving. Available in a full range of lengths from 42mm up to 212mm, so whether you are fixing a slim window frame into a block wall or a heavy timber beam into solid concrete, there is a size for the job.
Each screw features a T30 Torx drive recess, which gives good torque control and reduces driver wear compared to a standard Phillips or pozi head. If you have ever stripped a fixing halfway through a frame install, you will appreciate why that matters. The flat countersunk head has five locking ribs that bite into the frame surface and resist rotation once driven home.
Why These Masonry Frame Screws Work Well on Site
The thread design does a lot of the work here. A deep high-low thread profile cuts into the base material and locks in place, giving strong pull-out resistance across concrete, solid brick, perforated brick, hollow blocks and natural stone. Serrated V-threads help the screw cut cleanly through varied masonry types rather than jamming or wandering off line. The through-fixing method means you drill through the frame and into the substrate in one pass, which eliminates the separate step of marking up the wall before positioning the frame. That is particularly useful when fitting door frames to a tight reveal.
Each box of 100 comes with a Torx bit included, which is a small thing but worth noting if you are on a job without a full bit set to hand. The virtually stress-free expansion action also makes these suitable for close-edge applications where a traditional expansion anchor would risk splitting the masonry.
Pro Tip: Always use a rotary-only drill mode when driving these into perforated brick or hollow block, as hammer action can crack the web between cavities and dramatically reduce pull-out strength.
These frame screws are used daily by window installers, door hangers, joiners and general builders for fixing frames and structural timber directly into masonry substrates. Typical applications include window frame installation into brick and blockwork, external door frame fixing, timber batten and lath fixing to concrete walls, facade panel attachment, metal profile fixing and general through-fixing of structural timbers into solid or hollow masonry.
They perform well in both new build and renovation work where frames need to be fixed securely into existing masonry, particularly in situations where close-edge fixing is unavoidable and expansion-style anchors would be unsuitable.

Key Specifications
Diameter: 7.5mm
Lengths: 42mm to 212mm
Drive: T30 Torx
Head: flat countersunk with 5 locking ribs
Thread: deep high-low with serrated V-threads
Box quantity: 100
Torx bit included
Not suitable for: Not suitable for fixing into timber-to-timber connections or soft substrates such as sand-lime render without a solid masonry substrate behind. Not recommended for wet or permanently submerged conditions without appropriate corrosion protection.
Drill a pilot hole through the frame and into the masonry to the correct depth for the screw length being used. Hold the frame in position, insert the screw through the frame hole and drive with a T30 Torx bit until the countersunk head sits flush against the frame surface. No plug is required.
Select the correct screw length based on frame thickness plus the required embedment depth into the masonry substrate
Hold or prop the frame in its final position
Using a hammer drill in rotary-only mode for hollow materials, or rotary hammer for solid concrete and brick, drill through the frame and into the masonry in one pass
Clear any dust from the hole
Insert the frame screw through the frame and into the drilled hole
Drive with a T30 Torx bit until the countersunk head is flush with the frame face
Repeat at all fixing points, checking frame alignment as you work
Do I need a wall plug with these frame screws?
No. These are direct-fix screws designed to cut their own thread into the masonry substrate. The high-low serrated thread profile locks directly into concrete, brick or block, so no separate plug or anchor is needed.
What drill setting should I use when installing these into hollow block or perforated brick?
Use rotary-only mode, not hammer action. Hammer drilling into hollow block or perforated brick can crack the internal webs, which significantly reduces the holding strength of the fixing. Reserve hammer mode for solid concrete and dense solid brick.
These 7.5mm diameter frame screws are manufactured with a case-hardened steel body to withstand the torque required for direct masonry fixing. The T30 Torx recess minimises driver slip and bit wear under load. The deep high-low thread profile and serrated V-form cutting edges are designed to achieve maximum pull-out resistance across a range of masonry base materials, with a virtually stress-free installation action that reduces the risk of substrate cracking at close-edge positions.
