Interior Construction
Fasteners for furniture and built-ins
Build indoor furniture, fitted storage and outdoor pieces around joints that suit the material and the way the piece will be used.
Browse project fasteners Jump to installation stepsBuild furniture for everyday use
Start with the furniture material
Solid wood, plywood, MDF and laminates react differently to drilling, screw threads and moisture. Choose the material for the load, weight, finish and location, then test the fastener in the actual stock.
Choose a joint that fits the piece
A shelf, cabinet box and leg frame carry forces differently. Lay out the joints before choosing screw length, pilot holes or head style.

Six considerations when building furniture
-
Draw the piece
Sketch the overall shape and dimensions. Make a cut list and plan shelf supports, doors, drawers and fittings before buying material.
-
Compare the materials
Balance weight, strength, appearance and expected moisture. Choose edge treatments and hardware that suit the stock.
-
Measure and mark precisely
Check the room and stock in several places. Use a square to mark repeat cuts and trial-fit the parts before drilling.
-
Set up a safe work area
Support the work, clear the bench and use eye, hearing and dust protection appropriate to the tools and material.
-
Assemble with the right joinery
Choose a dado, dovetail, mortise-and-tenon or pocket joint as the design requires. Clamp square, test pilot depth and keep screw tips clear of finished faces.
-
Sand, finish and secure
Smooth the exposed edges and work through the grits specified for the finish. Follow the coating instructions, then install any specified wall restraint before use.
Match screws and pilot holes to the actual joint. Use separate anti-tip hardware where the furniture requires it.
Match head style to the joint
CabiMax™ provides a low-profile head where a compatible joint calls for a broad bearing surface. Consider MultiGrip™ for suitable everyday wood assembly and test the seating depth on an offcut.
Check the connection before you build

About this guide
A built-in succeeds when the carcass is square, the joints are planned and the wall anchorage is treated as its own task. Start with a measured sketch and assemble a small test joint before making the full run.

Keep assembly screws, shelf connections and wall-restraint hardware on separate schedules. A neat assembly joint does not establish the load rating of a shelf or anti-tip connection.
Read the evidence: VERTEXA catalog = listed product information. Material reference = requirements for the named material/system. Worked example = assumed inputs and arithmetic. Project input = a value to verify for your job.

| Tip clearance | Remaining cover = receiving thickness − geometric screw reach. Keep the point inside the work and away from wiring. | Project input |
| Assembly thickness example | A 1-1/2 in. screw through 3/4 in. material has 3/4 in. geometric reach. In a 1 in. receiver, remaining cover is 1/4 in. | Worked example |
| Timber movement | Solid-wood tops and wide panels need a movement detail suited to grain direction and seasonal change; do not rigidly fix every direction. | Project input |

Gather your tools
Tape, square and pencil; stud/utility detector; saw and work supports; clamps; drill/driver and matched bit; pilot/countersink tools; long level; shims and protective equipment.
Choose the right size
For ordinary wood assembly, select a MultiGrip size that passes through the first piece, engages the receiving wood and leaves clearance before the back face. For example, a nominal 2" screw through a 3/4" face leaves about 1-1/4" in the receiving piece. This is a geometry check, not a load rating.
Compare the relevant productsStep 1: Measure the room and the material.
Sketch the width, height, service locations and opening clearances. Measure panel thickness at an offcut. Mark wall studs for the final anti-tip or built-in restraint, and allow doors, drawers and outlets to remain usable.
- Tools for this stepTools
- Tape, square, pencil and detector.
- Size & quantity checkSize / count
- Record dimensions in inches; 3/4" is an example panel thickness, not a promise about your material.
Step 2: Design and count each joint.
Label carcass, shelf, face-frame and wall connections separately. Choose a joinery method suitable for the material; thin particleboard edges and end grain need their own appropriate detail. Count the screws on a drawing before cutting.
- Tools for this stepTools
- Drawing, tape, calculator.
- Size & quantity checkSize / count
- 12 joints × a planned 2 screws = 24 assembly screws. Keep wall anchorage separate.
Check both engagement and point clearance
Drawing explanation & numbered notes
The example is a simple perpendicular assembly joint. It is not a pocket-hole detail or a furniture load test.
- First layer. Measure the actual assembled thickness after rebates or countersinks.
- Receiving layer. Keep sufficient material around the fixing and verify the useful thread engagement.
- Reverse face. Subtract the reach from receiving thickness; an exposed point can damage the finished surface or injure the user.
Step 3: Select length and make a test joint.
Check first-piece thickness, receiving depth, head seating and point clearance. Pilot two representative offcuts using the actual screw. Confirm the faces pull together without splitting, stripping or a point appearing at the back.
- Tools for this stepTools
- Offcuts, clamps, drill/driver, matched Torx bit.
- Size & quantity checkSize / count
- A #8 × 2" option through 3/4" material leaves approximately 1-1/4" beyond the first piece; verify that depth exists.
Step 4: Assemble square, then fit the opening.
Clamp each unit square before fastening. Compare diagonal measurements and keep the unit supported while driving. Move the assembly into place, shim at load-bearing points and check door and drawer openings again.
- Tools for this stepTools
- Clamps, square, long level, shims.
- Size & quantity checkSize / count
- Use the number of screws from the joint drawing. Recheck diagonals after each main assembly.
Separate assembly from wall restraint
Drawing explanation & numbered notes
Build the carcass square first; plan wall restraints independently of the screws used to assemble shelves and dividers.
- Assembly joints. Count the actual repeated connections, including concealed back rails.
- Shelf supports. Use the shelf/hardware loading and span requirements; an assembly screw count is not a shelf rating.
- Wall restraint. Fix the specified restraint to suitable structural support using its own instructions.
Step 5: Restrain the finished unit correctly.
Locate the verified backing and install the furniture maker’s anti-tip bracket or built-in fixing detail. Match the bracket, wall type and rated hardware. A tall unit needs restraint before shelves are filled.
- Tools for this stepTools
- Detector, maker-specified brackets, driver and matched bit.
- Size & quantity checkSize / count
- Use the bracket maker’s required size and quantity. Count this hardware as a separate purchase.
Step 6: Finish, calculate and load gradually.
Check every head, exposed point and moving part. Add the chosen allowance to each assembly screw line and use the calculator if you need help. Record shelf loads from the furniture design and keep heavier contents low.
- Tools for this stepTools
- Checklist, calculator and light.
- Size & quantity checkSize / count
- 24 assembly screws + 10% = 27, rounded up; wall and anti-tip fasteners remain additional.
Work through the numbers
Inches for connection dimensions. Feet only where shown. Round piece and pack counts up; never round required engagement down.
Calculate the cover behind the point
Reach = 1-1/2 − 3/4 = 3/4 in.
Cover = 1 − 3/4 = 1/4 in.
Assumptions & calculation notes
Geometric reach includes the tip. Countersinking changes the length stack and reduces remaining cover. Confirm on an offcut before assembly.
Split the material list by function
12 assembly joints × 2 planned screws = 24
ceil(24 × 1.10) = 27
Assumptions & calculation notes
Order wall restraints and shelf hardware separately; they have different requirements and are excluded from this assembly count.
Inspect before you cover or load it
| Check | Accept when | If it fails |
|---|---|---|
| Carcass | Diagonals meet the project tolerance; no racked joints or exposed points. | Re-square and correct the joint before fixing to the wall. |
| Movement | Wide solid-wood elements can move as specified by the joinery detail. | Use approved slots or movement hardware where required. |
| Restraint | Specified tip-over restraints are installed to appropriate support. | Complete before loading the furniture. |
Know how much to order.
Example: 12 ordinary assembly joints with a planned 2 screws at each joint need 24 screws, or 27 with 10% extra. Add the furniture maker’s separate wall/anti-tip anchorage schedule.

Project questions
Which family should I start with?
Start with CabiMax for cabinet boxes and cabinet fixing points, or MultiGrip for general wood assembly. The head style and joined materials decide the final choice.
What should I check at narrow edges?
Check material thickness, edge distance and the project detail. Test the selected fastener on representative material when the finish or splitting risk matters.
