Depth Collar Setup

Before drilling your first hole, you must set the depth collar on both the drill bit and the driver bit. The depth collars help you achieve the proper hole and screw depth, ensuring the strongest possible joint with minimal exposure to the elements.

Note Follow the instructions for either non-grooved or grooved decking, depending on the type of boards you are using for your project.

Tip After initial depth collar setup, check the settings from time to time to ensure that each depth collar is still set correctly.

1 Set the Depth Collar on the Drill Bit

This depth collar controls hole depth and the position where the "shoulder" stops the screw.

For non-grooved decking:

a. On the Deck Jig (A), locate the gauge (1) labeled "Drill Bit Setting."
b. Place a depth collar (H) into the recessed slot and use a hex wrench (I) to hold it in position.
c. Slide the drill bit (F) through the depth collar (H) until the shoulder (2) of the drill bit (F) aligns with the dashed line.
d. Use the hex wrench (I) to tighten the depth collar (H) to the drill bit (F) securely.

2 1 DRILL BIT H F SETTING A

For grooved decking:

a. Place the Deck Jig (A) at the end of a grooved deck board.
b. Slide the drill bit (F) into the center drill guide (1) until the drill bit shoulder (2) is even with the bottom of the groove in the deck board.
c. Holding the drill bit (F) in this position, slide the depth collar (H) onto the drill bit (F) until the depth collar (H) rests against the drill guide (1).
d. Use the hex wrench (I) to tighten the depth collar (H) to the drill bit (F) securely.

A 1 F H 2

2 Set the Depth Collar on the Driver Bit

This depth collar controls the depth of your screw. When set properly, this depth collar prevents you from over-driving the screw.

For non-grooved decking:

a. On the Deck Jig (A), locate the gauge (1) labeled "Driver Bit Setting."
b. Place a depth collar (H) into the recessed slot and use a hex wrench (I) to hold it in position.
c. Slide the driver bit (G) through the depth collar (H) until the square tip (2) of the driver bit (G) aligns with the dashed line of the center drill guide.
d. Use the hex wrench (I) to tighten the depth collar (H) to the driver bit (G) securely.

1 2 G H DRIVER BIT SETTING A

For grooved decking:

a. Place the Deck Jig (A) at the end of a grooved deck board.
b. Slide the driver bit (G) into the center drill guide (1) until the square tip (2) of the driver bit (G) is even with the bottom of the groove in the deck board.
c. Holding the driver bit (G) in this position, slide the depth collar (H) onto the drive bit (G) until the depth collar (H) rests against the drill guide (1).
d. Use the hex wrench (I) to tighten the depth collar (H) to the driver bit (G) securely.

Operation

The Kreg Deck Jig allows you to drill a specialized hole at an optimized angle to secure your deck boards to the deck joists.

The hole is created by a stepped (or shouldered) drill bit which drills the pocket hole and pilot hole for the screw in one simple motion. The depth of the hole is controlled by a depth collar.

The Kreg Deck Jig also guides your screw as it is driven, so that the screw follows the exact path necessary and so that you won't overdrive or under-drive the screw.

Important! Driving your screws without the use of the depth collar and/or the Kreg Deck Jig can cause over-driving. Over-driving can lead to a joint with significantly reduced strength and increases the potential for excessive moisture build-up on the screw head.

1 Before You Begin

a. Check the depth collars:

■ Ensure that a depth collar (H) is securely attached to the drill bit (F) and to the driver bit (G).
■ Ensure that the placement of each depth collar (H) is appropriate for your decking (either non-grooved or grooved).

Note See Depth Collar Setup on page 5.

H F H G

b. For grooved decking: Test the screw placement:

With the depth collars set on the drill bit and driver bit, test-drive a deck screw into a scrap of grooved decking and check the results:

■ The bottom of the screw head should bear against the bottom lip of the groove.
■ None of the screw shank should be exposed, but the head should not be buried.

Make any necessary adjustments to the position of the driver bit stop collar; then retest the screw placement.

A H

Note Ensure that the screw head is not buried. Burying the screw head in the bottom lip of the groove could cause the lip to split.

2 Drill a Pocket Hole and Pilot Hole

a. Align the appropriate drill guide (1) over the deck board.

Note Review the recommendations in Hole Placement on page 9 for guidance on which drill guide is best for a given hole.

b. Place the drill bit (F) with attached depth collar (H) into your drill.

c. Insert the drill bit (F) into the drill guide (1) and bring your drill up to speed before contacting the deck board to ensure correct rotation of the driver bit.

d. Drill until the depth collar (H) contacts the drill guide (1).

e. Remove the drill bit (F) from the drill guide (1) while the drill bit is still rotating.

3 Drive a Screw

Note For information on choosing deck screws, see Deck Screws on page 13.

a. Place the driver bit (G) with attached depth collar (H) into your drill.

b. Realign the drill guide (1) with the hole that you just drilled.

c. Place a screw (2) directly into the drill guide (1).

d. Ensure that the screw (2) is correctly positioned to enter the hole; then drive the screw (2) when ready.

e. Drive the screw (2) until the depth collar (H) on the driver bit (G) reaches the drill guide (1).

Hole Placement

The Kreg Deck Jig provides three drill guides to accommodate different situations: a center guide (1) and two angled guides (2).

General guidelines:

■ Whenever possible, use the center guide (1) in the center of the joist. This hole placement provides the strongest joint.
■ When the edge is obstructed or when you are splicing two boards on the center of a joist, use either of the angled guides (2).
■ When you cannot position the jig effectively, drive a face-screw to secure the board.

Specific situations are described below

Note The suggestions in this section are provided as guidance, only.

When you are screwing along the length of the board with no obstructions, use the center drill guide (1) aligned with the center of the joist.

Note This hole placement is the most common type.

Obstructed edge

When the edge of your deck board is obstructed by a wall, or when the edge is on the outside of the deck where you cannot use angled holes, drive your screws from the top side of the deck board (face-screw).

Drilling Ends

Unobstructed end

When you are securing the end of a board and you can position the Deck Jig past the board (that is, when the Deck Jig is not obstructed by a wall), use the center drill guide (1) for superior strength.

Drilling 45° Decking

When you are securing deck boards at a 45^ angle from the joists, place the center drill guide (1) at the intersection of the joist and the deck board.

Then drill using the dashed line as an alignment guide.

Drilling Stair Treads

Start at the bottom of the stairs and work your way up so that you always have room to drill holes and drive screws.

If you plan to put risers on the stairs, install all the treads before you install the risers.

For the inner tread:

■ Use either of the angled drill guides for the inner long edge (1).

Using Spacer Rings

Three 1/4" spacer rings are included with your Deck Jig. These spacer rings act as a guide to help you create consistent spacings between one deck board and the next.

Building your deck with the proper 1/4" minimum spacing between boards allows debris to fall through for a clean deck. More importantly, the spacing ensures proper air movement to reduce moisture buildup.

Tip Also check your decking manufacturer's spacing recommendations.

a. Place the spacers (J) between a secured board (X) and an adjacent unsecured board (Y).
b. Using the Deck Jig, drill holes and drive screws into all the joists along the outer edge (1) of the unsecured board (Y).

Note Always drill the edge of the board that is opposite the spacers first (that is, the outer edge), so that the pressure of drilling and driving pushes toward the spacers.

c. Remove the spacers (J).
d. Drill holes and drive screws into all the joists along the inner edge (2) of the unsecured board (Y).

Note Now the pressure of drilling and driving pushes back against the edge of the board that is already held in place by the screws (3).

Choosing a Deck

This section describes some considerations to take into account when selecting material and screws for your deck.

Decking Material

The Kreg Deck Jig works with almost any type of decking material. These types are some of the most popular materials:

■ ACQ pressure-treated lumber: Usually made from pine, “Green Treat” lumber is one of the most affordable types of decking material. This material commonly suffers from shrinking, swelling, and splitting. It will not last as long as many other types of decking.
■ Composite Material: Composite decking is often made from a combination of wood fibers and plastic. It is more expensive than pine, but lasts much longer and is less prone to shrinking, swelling, and splitting. Composite is our recommended decking material.
■ Exotic Hardwoods: Exotic woods such as ipe are much harder and more dense than traditional pine. As a result, they last longer, look better, and cost more. Exotic woods still require treatment to prevent discoloration and water damage.

Deck Screws

Kreg Deck Screws were designed specifically for use as concealed fasteners with the Kreg Deck Jig. These screws can also be used as simple face-screws for a variety of outdoor projects.

Protection from Corrosion

Kreg Deck Screws are available in two types:

■ Protec-Kote™: Three anti-corrosion layers protect against rusting in a wide variety of decking applications; perfect for ACQ-treated lumber.

■ Stainless: For even more protection, choose stainless. Stainless screws provide the best long-term protection against corrosion and are suited for marine applications.

Screw Length

Choose the screw length based on the thickness of your decking material.

Material Thickness Screw Length
4/4 to 5/4 (3/4" to 1-1/8") 2"
1-1/2" 2-5/8"
