Ipe Decking Fasteners: Hidden Clips vs. Screws vs. Plugged Screws

The boards are beautiful. Now the question every ipe installer faces: how do you fasten them? Your fastener choice affects the deck’s appearance, installation time, cost, and long-term performance. This guide breaks down the three main options for ipe decking — hidden clips, face screws, and plugged screws — so you can make the right call for your project.

Why Fastener Choice Matters More with Ipe Than Other Wood

Ipe is exceptional decking — but it’s not forgiving of installation mistakes. At 66 lbs per cubic foot, ipe is one of the densest woods you’ll work with. Every fastener approach requires pre-drilling to prevent splitting. Ipe also expands and contracts with temperature and moisture, so the fastener system must accommodate movement without cracking boards or loosening over time.

Get the fastener choice wrong and you’re dealing with split boards, raised fasteners, or a deck that looks great from 10 feet away but shows every screw from the deck chairs. Get it right and you have a deck that performs flawlessly for decades.

Option 1: Hidden Deck Clips (Ipe Clips)

Hidden clip systems attach to the sides of each board, with no fasteners visible on the deck surface. The industry standard for ipe is the Ipe Clip® Extreme, which uses a grooved or biscuit-slot approach. Each board gets a slot cut into both long edges with a biscuit joiner, and the clips slide into those slots and attach to the joist below.

Advantages of Hidden Clips

• Clean appearance — no fasteners visible from above. The deck surface looks like solid wood from end to end.
• Accommodates movement — clips allow slight lateral movement as boards expand and contract seasonally.
• Protects board edges — the clip sits in the groove, protecting the board edge from impact and moisture wicking.
• Faster than plugging — once you have the groove-cutting process down, clip installation is fast.

Disadvantages of Hidden Clips

• Requires a biscuit joiner — you need a specialized tool (or pre-grooved boards from the supplier).
• Higher material cost — clips add $0.50-$1.00 per linear foot over face-screw systems.
• Not ideal for all joist configurations — works best with standard 16″ OC spacing. Tight spaces near walls or stairs require supplemental face fasteners anyway.
• Harder to replace individual boards — removing a damaged board mid-deck requires more work than with face screws.

Best Applications for Hidden Clips

Residential decks where aesthetics are the priority. Decks visible from the house interior or from neighboring properties. Projects where clients are paying for premium materials and expect a premium look. Any deck where the “no fastener holes” appearance is a selling point.

Option 2: Face Screws (Pre-drilled)

Face screwing is the most traditional approach: drill through the face of each board into the joist below. With ipe, pre-drilling is not optional — it’s mandatory. You need to drill a pilot hole for the shank, plus a countersink for the screw head. Use stainless steel screws (305 or 316 grade) or coated deck screws rated for hardwoods. Standard galvanized screws will corrode and leave rust stains in ipe within a few seasons.

Advantages of Face Screws

• Lowest cost — screws are cheap. No special clips, no biscuit joiner.
• Fastest installation — drill and drive. Experienced installers can face-screw an ipe deck significantly faster than a clipped or plugged deck.
• Easy board replacement — back out the screws, swap the board, redrive.
• Works in any configuration — edges, stairs, curves, tight spots.

Disadvantages of Face Screws

• Visible fasteners — screw heads are visible on the deck surface. Acceptable to many homeowners, objectionable to others.
• Must be exactly flush — a countersunk screw that’s slightly proud creates a trip hazard. Over-countersunk creates a hole that collects water and debris.
• Risk of split if not pre-drilled correctly — ipe does not forgive installation without proper pilot holes.

Best Applications for Face Screws

Commercial installations, contractor projects on tight timelines, decks where budget is the primary constraint, decks that aren’t highly visible, and first-board/last-board placement on any clipped deck system.

Option 3: Plugged Screws (Countersunk and Plugged)

Plugged screws are the premium version of face screwing. You drive a face screw as normal, but instead of leaving the countersunk hole visible, you glue in a matching ipe plug that covers the hole completely. The result is a nearly invisible fastener — you can see the plug grain if you look closely, but from normal viewing distance, the deck looks clean.

Advantages of Plugged Screws

• Clean look without groove-cutting — achieves near-hidden-fastener appearance without a biscuit joiner.
• Strong mechanical connection — screws pull directly down into the joist.
• Works anywhere face screws work — edges, angles, non-standard joist spacing.
• Ipe plugs match the decking wood — when sourced from the same material, the grain blends naturally.

Disadvantages of Plugged Screws

• Slowest installation method — each hole requires drilling, countersinking deep enough for the plug, driving the screw, gluing the plug, and cutting it flush. Budget roughly 3x the labor time vs. face screws.
• Plugs can crack over time — especially in climates with extreme seasonal temperature swings. The plug and the board move at slightly different rates.
• Nearly impossible to remove screws later — if you need to replace a board, you’re drilling out every plug over that board’s length.

Best Applications for Plugged Screws

High-end residential projects where clients want a clean look but the installer doesn’t have a groove-cutting setup. Perimeter boards and stair nosings on clipped-deck systems. Any location where clips can’t reach.

Hardware Specifications: What to Use with Ipe

Whatever fastener method you choose, the hardware matters. Ipe’s natural oils are slightly acidic and will corrode standard fasteners over time. Use:

• 316 stainless steel screws for coastal/high-humidity environments
• 305 stainless steel for inland/lower-humidity climates
• Length: 2.5″ to 3″ for standard 1″ decking boards (you need 1.5-2″ into the joist)
• Star/Torx drive — do not use Phillips with ipe. The torque required to drive into this hardwood will cam out a Phillips drive before the screw is flush.

The Bottom Line: Which Should You Choose?

For most residential projects where aesthetics matter: use hidden clips. The cost premium is modest relative to the total project cost, and the clean look is worth it. If budget is tight or timelines are short: face screw with 316SS screws and don’t apologize for it — properly done face screws look fine and hold forever. Plugged screws make sense for specific applications but are rarely the right choice for an entire deck run due to the labor cost.

Whatever you choose, pre-drill every hole. Ipe will split if you don’t. It’s not optional.
