The roof of the Expo 2000 in Germany
approx. 10,000,000 screws are in use here, to ensure the permanent
strength of the wood.

Modern screw connectors
Modern screw connectors today are:
• Self-tapping screws for use in timber structures
• No pre drilling is required (except hardwoods)
• The main characteristics are:
- thread: full or partial threaded
- head shapes
Modern screw connectors
Full thread or Partial thread
Full thread
- for long screws no clamping effect
- with remarkably high load bearing capacity
in tension as well as in compression
- inclined screws can work as framed truss
Partial thread
- with clamping effect, pull together
- clamping effect is depending on head shape
and size
Modern Screw Connectors
Main head shapes and recess
Washer headCountersunk SPAX T-STAR plus recess for
best driving home performance
Modern screw connectors
Countersunk head
• Main use for full threaded screws
• Flush counter sinking in timber
• Small head diameter for reduced visibility
• For partial threaded screws small load bearing
capacity in tension due to head diameter
• Can be used also in counter sunk steel plates for steel to
timber connections
Application examples: Countersunk Screws
Wall fastening, timber frame construction
Secure joining of wall
elements, for example
Modern Screw Connectors
Washer head
• Best use for partial thread screws
• Plain contact to timber
• Big head diameter
• For partial threaded screws high load bearing
capacity in tension due to big head diameter
Application examples: Wascher Head Screws
Fastening rafters, purlin
Fastening the rafters, pulled
tightly together using the
washer head screw.
No purlin anchors / triple grip
necessary
High wind uplift load bearing
capacity
Modern Screw Connectors
Cylindrical head
• Only use for full thread screws
• Flush counter sinking with timber, or
slightly deeper sinking possible
• Very small head diameter for reduced visibility
• Is not recommended for use in
steel to timber connections
• Also data on screw reinforcement available from Expan
Application examples: Fully Threaded Screws
Transverse tensile reinforcement in accordance with DIN 1052:2008
Reliable alternative to bonded
reinforcement boards and glued
thread rods
Work can be performed by any
carpenters shop
No bonding approval required
Work can also be reliably performed
on site (e.g. restoration of buildings)

Pre-Drilling
Do not exceed maximum drive torque
Pre-drill size should be shank Ø of the screw
Pre-drilling as a locating guide for easy installation
Corrosion control
Zinc: for internal use only
Hot dip galvanize: for external use in low corrosive areas. (Low
tensile fasteners only)
Delta-Seal: ideal for treated timber in low corrosive areas
Stainless Steel: in exposed high corrosive areas

  • 1. Seite 1 Modern screw connectors Design and use in CLT, Gluelam and LVL By Michael Koenig
  • 2. Topics Pictures of projects • Expo Roof • Airport Paris • Mt Ruapehu • Waitomo Caves Modern screw connectors • Partial thread and full thread and field of use • Head shape and recess • Samples of connections • Pre drilling • Corrosion issues Technical information • Where to get information from
  • 3. The roof of the Expo 2000 in Germany approx. 10,000,000 screws are in use here, to ensure the permanent strength of the wood.
  • 4. Charles de Gaulle Airport, Paris
  • 6.
  • 7. Steel to Timber connection
  • 8. Knoll Ridge Cafe, Whakapapa NZ
  • 9. Knoll Ridge Cafe, Whakapapa NZ
  • 12. Modern screw connectors Modern screw connectors today are: • Self-tapping screws for use in timber structures • No pre drilling is required (except hardwoods) • The main characteristics are: - thread: full or partial threaded - head shapes
  • 13. Modern screw connectors Full thread or Partial thread Full thread - for long screws no clamping effect - with remarkably high load bearing capacity in tension as well as in compression - inclined screws can work as framed truss Partial thread - with clamping effect, pull together - clamping effect is depending on head shape and size
  • 14. Modern Screw Connectors Main head shapes and recess Washer headCountersunk SPAX T-STAR plus recess for best driving home performance
  • 15. Modern screw connectors Countersunk head • Main use for full threaded screws • Flush counter sinking in timber • Small head diameter for reduced visibility • For partial threaded screws small load bearing capacity in tension due to head diameter • Can be used also in counter sunk steel plates for steel to timber connections
  • 16. Application examples: Countersunk Screws Wall fastening, timber frame construction Secure joining of wall elements, for example
  • 17. Modern Screw Connectors Washer head • Best use for partial thread screws • Plain contact to timber • Big head diameter • For partial threaded screws high load bearing capacity in tension due to big head diameter
  • 18. Application examples: Wascher Head Screws Fastening rafters, purlin Fastening the rafters, pulled tightly together using the washer head screw. No purlin anchors / triple grip necessary High wind uplift load bearing capacity
  • 19. Modern Screw Connectors Cylindrical head • Only use for full thread screws • Flush counter sinking with timber, or slightly deeper sinking possible • Very small head diameter for reduced visibility • Is not recommended for use in steel to timber connections • Also data on screw reinforcement available from Expan
  • 20. Application examples: Fully Threaded Screws Transverse tensile reinforcement in accordance with DIN 1052:2008 Reliable alternative to bonded reinforcement boards and glued thread rods Work can be performed by any carpenters shop No bonding approval required Work can also be reliably performed on site (e.g. restoration of buildings)
  • 21. Roller coaster Liseberg Stockholm, Sweden Split control of engineered dowel connections
  • 22. EXPAN Quick-Connect Rafter Sleeves (steel rods inside) Screws Bearing plates Column
  • 23. Design of connection detail Spacing of screws
  • 24. CLT – standard details Corner joint Exterior wall partial thread sealing tapes for air tight shell Picture: Building with cross laminated timber of Studiengemeinschaft Holzleimbau e.V.
  • 25. CLT – standard details Ceiling connection Platform framing partial thread sealing tapes for air tight shell Picture: Building with cross laminated timber of Studiengemeinschaft Holzleimbau e.V.
  • 26. CLT – standard details Roof connection Eave detail partial thread sealing tapes for air tight shell Picture: Building with cross laminated timber of Studiengemeinschaft Holzleimbau e.V.
  • 27. CLT – standard details Wall connection vertical Partial thread with connection splice plate Picture: Building solutions of Stora Enso
  • 28. CLT – standard details Ceiling connection with connection splice plate Partial thread Picture: Building solutions of Stora Enso j
  • 29. CLT – standard details Picture: Building solutions of Stora Enso Ceiling connection Full thread with reinforcement, full thread
  • 30. CLT – standard details Picture: Building solutions of Stora Enso Top bearer connection with steel beam Full thread J v J v
  • 31. CLT – standard details Picture: Building solutions of Stora Enso Top bearer connection with upper CLT wall Full thread
  • 32. Pre-Drilling Do not exceed maximum drive torque Pre-drill size should be shank Ø of the screw Pre-drilling as a locating guide for easy installation
  • 33. Corrosion control Zinc: for internal use only Hot dip galvanize: for external use in low corrosive areas. (Low tensile fasteners only) Delta-Seal: ideal for treated timber in low corrosive areas Stainless Steel: in exposed high corrosive areas

Editor's Notes

  1. Give timeline, locations of toilets etc, introduce speakers
  2. This chapter is more for the budding engineer, it gives a complete explanation of the loads listed and gives a comprehensive design example to follow
