1Gap spacing

Our line of deck fasteners offer a vast array of gap spacing options. Whether installing air or kiln dried hardwood, thermally modified softwood, composite or PVC decking, we have the appropriate fastener with at least three different gap spacing options for your particular decking.

2Stainless Steel Insert

Ipe Clip® stainless steel insert

Corrosion resistant, black oxide stainless steel insert increases hold down strength and eases installation by helping to prevent over-driving of screws.

Cutting Decking Grooves

Many lumber yards now offer pregrooved materials in stock.


Cut the groove yourself using a standard biscuit joiner or router with a 5/32" slot cutter.

4Screws Driven at 45°

Ability to run screws at a 45 degree angle through hardwoods greatly increases hold-down strength. Studies have proven that screws have more holding strength when ran on an angle. This method also maintains even gap spacing while properly allowing boards to expand and contract with the seasons.

A = 5/32" (4mm)

B = 1/2" (13mm)

C = Measurement of the deck board thickness being installed

D = (C-A)/2 Note: This will center the groovein the board

1x6 Example

Let's say you are installing 1x6 decking, that would mean that:

  • C = 3/4"
  • D = (3/4" - 5/32")/2
  • D = (19/32")/2
  • D = 19/64" (7,54mm)

5/4x6 Example

Let's say you are installing 5/4x6 decking, that would mean that:

  • C = 1"
  • D = (1" - 5/32")/2
  • D = (27/32")/2
  • D = 27/64" (10,72mm)
