Festool DOMINO Sipo D 8x50/300 MAU Loose Tenons

At a Glance: 300 weatherproof Sipo hardwood DOMINO loose tenons measuring 8 × 50mm for strong, twist-resistant indoor and outdoor joinery.

The Festool DOMINO Sipo D 8x50/300 MAU loose tenons are premium joining elements designed for strong and accurately aligned joints in solid timber and suitable panel materials. Manufactured from durable Sipo hardwood, they are naturally resistant to insects, mould and weather exposure, making them particularly well suited to outdoor furniture, exterior joinery and other demanding applications.

The distinctive DOMINO profile combines the alignment advantages of a flat biscuit with the strength of multiple conventional round dowels. Its elongated shape locks the workpieces against rotation from the very first tenon, while the broad contact surfaces provide excellent mechanical stability and a generous area for adhesive bonding.

Specially formed glue pockets and longitudinal grooves help distribute adhesive evenly throughout the joint. They also allow excess glue to escape as the tenon is inserted, helping the components seat fully and creating a secure, dependable connection. Projecting guide ribs centre the DOMINO inside the routed mortise for precise workpiece alignment and clean, flush assembly.

Weatherproof DOMINO strength for demanding joinery

Sipo DOMINOs are developed specifically for applications where ordinary interior-grade beech tenons may not provide sufficient resistance to moisture, insects and fungal attack. Combined with Festool&s precise DOMINO mortising system, they create fast, stable and rotation-proof joints for furniture, shopfitting and exterior timber projects.

Product Highlights

  • Weatherproof Sipo hardwood: Naturally resistant to insects and mould and ideally suited to outdoor applications.
  • Exceptional joint stability: The cross-section provides strength comparable to three round dowels of the same drilling diameter.
  • 100% rotation resistant: The unique DOMINO shape locks the joint against twisting from the first tenon.
  • Perfect workpiece alignment: Projecting guide ribs centre the tenon inside the DOMINO mortise.
  • Optimised glue distribution: Special glue pockets and longitudinal grooves spread adhesive evenly through the joint.
  • Cleaner assembly: Side grooves allow excess adhesive to escape so the tenon can seat correctly.
  • Quick size identification: The dimensions are imprinted directly on each DOMINO.
  • Responsible material sourcing: Manufactured from FSC™-certified timber.

Features

  • Sipo hardwood construction: Provides natural resistance to weather, insects and mould.
  • 8 × 50mm nominal size: Suitable for substantial furniture and structural woodworking joints.
  • Patented DOMINO profile: Combines the advantages of round dowels and flat biscuits.
  • Laterally projecting guide ribs: Centre the tenon within the routed mortise for accurate alignment.
  • Expanding glue pockets: Help create a secure grip and distribute adhesive through the joint.
  • Longitudinal grooves: Allow excess glue and trapped air to escape during insertion.
  • Imprinted dimensions: Make the correct tenon size quick and easy to identify.
  • Broad machine compatibility: Suitable for Festool DF 500, DF 500 R, DFC 500 and DF 700 joining machines.

Benefits

  • Long-lasting outdoor joints: Sipo timber withstands moisture and outdoor conditions better than standard interior-grade tenons.
  • Strong mechanical connection: The substantial cross-section provides excellent resistance to movement and joint failure.
  • Fast assembly: The self-aligning shape helps position workpieces accurately during glue-up.
  • Reduced joint slippage: Rotation-proof geometry keeps components aligned while clamps are applied.
  • Excellent adhesive performance: Grooves and pockets promote consistent glue coverage.
  • Cleaner glue-up: Excess adhesive can escape rather than preventing the tenon from seating fully.
  • Repeatable precision: Exact manufacturing dimensions provide a reliable fit in correctly routed DOMINO mortises.
  • Efficient workshop supply: The 300-piece pack is ideal for frequent professional use and production work.

Application

  • Outdoor furniture construction.
  • Exterior doors, windows and frames.
  • Garden structures and timber features.
  • Strong joints in solid wood.
  • Joining suitable wood-based panel materials.
  • Furniture manufacturing.
  • Shopfitting and exhibition construction.
  • Interior fitting and cabinetmaking.
  • Projects requiring weatherproof, twist-resistant loose-tenon joints.

Extra Information

  • The D 8x50/300 MAU pack contains 300 Sipo hardwood DOMINO loose tenons.
  • Each tenon measures 8 × 50 × 21.9mm.
  • The tenons are compatible with Festool DF 500, DF 500 R, DFC 500 and DF 700 joining machines.
  • The 8 × 50mm size falls within the working range of both the DF 500 system and the DOMINO XL DF 700 system.
  • Sipo DOMINOs are intended especially for outdoor projects and other applications exposed to moisture.
  • For interior-only applications, Festool also offers beech DOMINOs in various sizes.
  • All DOMINOs originate from sustainable forest management and controlled sources and carry FSC™ certification.

Pro Tips

  • Use a suitable exterior-grade waterproof wood adhesive when assembling outdoor projects.
  • Dry-fit the joint before applying glue to confirm mortise depth, spacing and workpiece alignment.
  • Apply adhesive to both the mortise walls and the DOMINO for complete bonding coverage.
  • Use one tight mortise for alignment and wider mortises for the remaining positions when assembling long components.
  • Keep the imprinted size marking visible during preparation to avoid mixing different DOMINO dimensions.
  • Store unused tenons in a clean, dry container to preserve their exact dimensions.
  • Clamp the assembly evenly and keep the workpieces square until the adhesive has fully cured.
  • Use multiple DOMINOs in wide or heavily loaded joints to increase strength and maintain alignment.

How to Use

  • Select a compatible Festool DOMINO joining machine and fit the correct 8mm cutter.
  • Mark the intended joint locations on both workpieces.
  • Set the mortising depth to suit the 50mm tenon length and the thickness of the workpieces.
  • Secure the first workpiece and route the required DOMINO mortises.
  • Route corresponding mortises in the mating workpiece using consistent reference faces.
  • Dry-fit the joint with the 8 × 50mm DOMINOs to confirm alignment and full seating.
  • Apply a suitable adhesive inside the mortises and to the tenon surfaces.
  • Insert the DOMINOs into one workpiece and bring the mating component into position.
  • Press the workpieces together until all tenons are fully seated.
  • Clamp the assembly evenly and check that it remains square and flush.
  • Remove excess adhesive before it cures.
  • Leave the joint clamped for the adhesive manufacturer&s recommended curing time.

Safety

  • Wear suitable eye, hearing and dust protection when operating the DOMINO joining machine.
  • Disconnect the machine from its power supply before installing or changing the cutter.
  • Only use the correct 8mm cutter and appropriate mortising depth for the selected DOMINO.
  • Secure each workpiece firmly before routing the mortises.
  • Keep hands, loose clothing and electrical cables away from the moving cutter.
  • Inspect the cutter before use and do not operate the machine with a damaged or blunt cutter.
  • Use an adhesive suitable for the material, environment and intended application.
  • Follow the adhesive manufacturer&s handling, clamping and curing instructions.
  • Store the DOMINOs in a dry location and protect them from uncontrolled moisture before use.
  • Follow all operating and safety instructions supplied with the Festool DOMINO joining machine.
