DECK FASTENING METHODS AND DECK FASTENERS
for Mataverde Premium Hardwood Decking
If you are using a high density hardwood decking material like Mataverde® Premium Ipe Decking for the first time, you will find that a new set of deck installation techniques and deck fasteners is required. Read on for helpful information regarding methods and products for use with all Mataverde Decking products.
DECKING SCREW DOWN METHODS
Screwing your Mataverde Premium Hardwood Decking to the deck substructure is the strongest method is securing your deck boards.
The two most effective methods of installing decking screws are:
The traditional pre-drilling, countersinking and deck screwing method which can be completed in two steps.
- The “Ejector Screw” deck screw method where the drilling, countersinking and screwing of deck screws are performed in one quick step.
Regardless of which screw-down method you choose to install your hardwood deck, the following chart is a handy guideline for estimating the proper quantity and placement of decking screws:

TRADITIONAL PRE-DRILLING AND SCREWING METHOD
A craftsman using high density hardwood decking for the first time will find that a new set of deck installation techniques and deck fasteners are necessary to successfully complete a decking project with maximum efficiency.
Hardwood Decking Installation Tips and Techniques for Traditional Screwing Method:
The first step is to pre-drill the decking boards.
A good countersink bit is necessary to fasten the wood decking. Tapered bits are preferable. They provide a good “slip hole” through the high density hardwood decking and a smaller tapered hole in the deck joist or framing.
Stainless steel deck screws are the only choice for fastening tropical hardwood decking.
The deck fastener life must match the longevity of the decking material being used. Tropical hardwood decking will significantly outlast galvanized or coated deck screws. Mataverde® Deck Screws are the finest grade of 305 stainless steel to last longer. We recommend #7 trim head square drive decking screws for either ¾” or 1" thick decking material. These deck screws use a #1 square drive driver to reduce “cam out”.
Technique is just as important as the material used!
The countersink hole should be made slightly deeper into the deck board than the head of the screw. This allows the head of the screw to be set slightly below the surface of the deck board. When shrinkage occurs, the head will be flush or just below the surface of the decking. It is very important that the countersink bit must be held at a right angle to the wood deck surface. The drill bit will break if there is too much pressure at an angle prior to finishing the drilling operation. Remember, Mataverde® Hardwood Decking products are among the hardest decking woods on earth.
Slow the speed of your drill down when you countersink.
Drill the hole to half depth, back the bit out and clean the drilling waste prior to finishing the hole in the deck board. This will reduce breakage, extend the life of the bit and countersink as well as provide a cleaner, more consistent hole in the deck board.
Go slow and steady when you install the deck screw into the decking.
This will prevent the screw from heating up excessively, distorting or breaking. If the deck screw starts to distort while driving it into the deck board, stop! Move on to the next deck screw. This will allow the decking screw to cool down before you stress it during the removal. Discard the deck screw and apply wax to the replacement deck screw threads. Drive the new deck screw slowly into the deck board.
What do you do if you break a deck screw?
Take a moment to determine what caused the breakage in the deck screw. Was the deck screw driven in to the decking too quickly? Did it hit another fastener or building hardware below the deck surface? Vise-Grip pliers are the tool of choice for removing broken decking screws. Clamp the pliers on the head or what is left of the deck screw on the surface and twist the screw out. If the deck screw breaks below the surface, drill a slightly angled hole adjacent to the broken deck screw. It is best to use a 1/8” drill bit to perform this rather than a tapered countersink. Wax a new deck screw and slowly and carefully install it next to the broken deck screw.

PRE-GROOVED HARDWOOD DECKING BOARDS
If you don’t have the inclination to cut slots into your decking boards, all Mataverde hardwood decking species are available as Pre-Grooved decking. This continuous groove makes decking installation much quicker whether you are installing your deck boards square or on a diagonal.
HIDDEN FASTENER OPTIONS
THE MATAVERDE® EUROTEC® DECK CLIP
(Hidden Fastener Method)
For a clean, unencumbered deck surface on a wood framed deck, many of our clients prefer a hidden deck fastener. To achieve this look, the Mataverde® Eurotec® Deck Clip is a great hidden fastening option for decking. To save lots of installation time and costs, you may want to use Mataverde® Premium Hardwood Decking product that is “pre-grooved” or “slotted” on the sides.
Unlike other hidden deck fasteners, the Mataverde Eurotec Deck Clip and screws are made from 100% stainless steel for long life and holding power. Both are coated black for low visibility. The extra long clip is ideal for aligning the decking, especially where the butt ends of two decking boards meet.
Rather than drilling and screwing through the face of the deck boards, the hidden fasteners are drilled and screwed on a 45 degree angle though the deck boards into the deck joists. The next pre-grooved deck board is then seated onto the deck fastener and the deck fastening process is repeated.
Because deck boards using this method are fastened on one side of the board only, we offer the following suggestions for best results and long-term satisfaction:
Installation Tips for best results using Mataverde Eurotec Deck Clips:
- Always use 21mm or 5/4 nominal thickness hardwood decking
- Always install a minimum of 36" above grade with adequate ventilation below your deck (3 sides open)
- Because it has a narrower face (and therefore less natural expansion and contraction as the wood 'seasons'), 21mm x 4 or 5/4 x 4 hardwood decking works the best for hidden fasteners
- 21mm x 6 or 5/4 x 6 decking (nominal sizes) may be used, but expect, and plan for, acclimation and natural shrinkage of these wider deck boards
The Mataverde Eurotec Deck Clip Kit includes:
175 Stainless Steel Deck clips (black for lower visibility)
190 Stainless steel screws (black for lower visibility)
1 drill bit
1 driver bit
Covers approximately 100 sf of 5/4x6 decking area
The Mataverde Eurotec Deck Clip Contractor Bucket includes:
525 Stainless Steel Deck clips (black for lower visibility)
570 Stainless steel screws (black for lower visibility)
2 drill bits
2 driver bits
Covers approximately 300 sf of 5/4x6 decking area
EB-TY® HIDDEN DECK FASTENER
If you prefer a deck where the deck fasteners are not visible, you may want to consider using a Mataverde® Premium Hardwood Decking product that is “pre-grooved” or “slotted” on the sides. Rather than drilling or screwing through the face of the deck boards, the hidden fasteners are screwed on a 45 degree angle though the deck boards into the deck joists. The next pre-grooved deck board is then seated onto the deck fastener and the deck fastening process is repeated.

EJECTOR DECK SCREW METHOD
A recent development in deck screw technology has created the “Ejector Screw”. This patented deck screw has a drill point, a coarse lower thread, a smooth upper shank and a countersink head. The drill point eliminates the need for pre-drilling your deck boards. The coarse thread drives the screw home. The smooth upper shank ejects the drilling waste. The countersink head eliminates the need for countersinking each deck hole. This amazing new deck screw performs all four steps in one smooth motion.
Whether you are a homeowner or a construction professional, the Ejector Screw will save you time and wear and tear on your body every time you install deck boards.
In addition to reducing the stress, strain and fatigue on your shoulders, arms, knees and lower back muscles while installing deck boards, the Muro Speed Driver can be used to accurately apply over 1,000 deck screws per hour. That makes it about five times faster than conventional drilling and deck screwing techniques.
