- Published screw specification
- #8 × 2-inch stainless T15 is a published kit configuration. Other lengths/alloys exist; match the supplied kit and joist. Do not treat all stainless screws as interchangeable.
The chart is species- and drying-specific. Do not choose a clip from species alone.
Ipe Clip Extreme: separate the measurements
- Installed gap
- 3/32 in (2.381 mm)
- Groove cut
- 5/32 in (3.969 mm)
- Groove depth
- 1/2 in (12.7 mm)
- Clip tab thickness
- Needs Verification: .148 in in the 2014 specification; .147 in on the current graphic
The groove cut is not the clip tab thickness. Published requirements do not verify the supplied milling or sold kit.

See what the screw actually penetrates
The angled screw penetrates the clip, the first board, then the joist. The next board seats on the free wing; its opposite edge gets the next fastener.
Read with the exact product instructions. Features are simplified for visibility; these are not production drawings or structural details.
Decisions for this connection
- The chart is species- and drying-specific. Do not choose a clip from species alone.
- Manufacturer evidence is separate from approval of the actual supplied profile and accessory SKU.
- Identify the preservative and treatment level; check fastener and connector compatibility with that treatment.
- Match the exact groove width, depth and position to the selected clip. The desired gap must agree with the documented system gap.
Field clip position study
For parallel continuous boards crossing the same supports, one clip position at each shared board edge on each support. This is a geometric scenario, not a fastening schedule.
Illustrated example: (3 boards − 1) × 3 supports = 6 positions.
