Features

Easy to Install

Efficiently Installs a Variety of Top-Plate-to-Rafter/Truss Assemblies

Instantly Positions Fastener at the Optimal Installation Angle

In this type of installation, when the angle
guideline is vertical (or if bubble is visible in
level), the SDWC screw is at the optimal angle
for top plate to rafter/truss connections.| In this type of installation, when the centerline
guide is vertical, the screw is at the optimal
90° angle for vertical connections into an offset
rafter/truss assembly.| In this type of installation, when the centerline
guide points to the middle of the rafter/truss and the angle guideline is vertical (or if the bubble is visible in the level), the SDWC Truss screw is at the optimal compound angle.

A Proven Connection

The Quik Stik system was designed for installing the Strong-Drive® SDWC
Truss screw (sold separately). The Strong-Drive SDWC Truss screw provides a connection that fastens rafters and trusses to top plates. Strong-Drive SDWC Truss screw features:

• The fully threaded shank engages the entire length of the fastener, providing a secure connection
• 6-lobe drive recess provides a secure connection between the driver bit and the SDWC cap head for consistent drive performance
• Drives easily without splitting wood
• Orange topcoat for easy inspection of code-listed 6″ truss screws
• The SDWC is tested in accordance with ICC-ES AC233 (screw) and AC13 (wall assembly and roof-to-wall assembly) for uplift and lateral loads between wall plates and vertical wall framing and between the top plate and the roof rafters or trusses
• Codes/Standards: IAPMO UES ER-262

SDWC15600| 0.152| 6| 53⁄4| 615| 130| 225| 485| 115| 190

1. Loads have been increased for wind and earthquake loading (C D = 1.6), no further increases allowed; reduce where other loads govern.
2. Allowable loads are for SDWC installed per the installation instructions. SDWC screws are shown installed on the interior side of the wall. Installation on the exterior side of the wall is also acceptable.
3. An SDWC screw may be used in each ply of two- or three-ply rafters or trusses. The allowable uplift load for each screw shall be multiplied by 0.90, but may be limited by the capacity of the plate or the connection between the top plate to the framing below. SDWC screws in multi-ply assemblies must be spaced a minimum of 1 1⁄2″ o.c.
4. Loads assume a minimum overhang of 3 1⁄2″.
5. For uplift connection load path, the Designer shall verify complete continuity of the uplift path.
6. When the screw is loaded simultaneously in more than one direction, the allowable load must be evaluated using the following unity equation: (Design Uplift ÷ Allowable Uplift) + (Design F2 ÷ Allowable F2 ) ≤ 1.0
7. Top plate, stud and top plate splice fastened per applicable Building Code.
8. Table loads do not apply to trusses with end-grain bearing.

Installation 1 Instructions — Rafter/Truss Offset from Stud:
Fasten Straight up Through Double Top Plate
These instructions apply only if the rafter/truss is offset from the stud below.

Installation Steps: Position the Quik Stik head directly under the top plate so that the screw is pointing toward the centerline of the rafter/truss.
Ensure the Quik Stik centerline guide is vertically perpendicular to the top plate.
Drive the SDWC Truss screw straight up through the top plates and into the rafter/truss until the head is flush with the board’s surface.

Installation 2 — Rafter/Truss Offset from Stud:
Fasten from Front-Bottom Corner of Double Top Plate
These instructions apply only if the rafter/truss is offset from the stud below

Installation Steps: Position Quik Stik so that the positioning prongs straddle the bottom edge of the double top plate and with the SDWC screw set to enter the bottom member along its edge. Ensure the Quik Stik centerline guide points to the center of the rafter/truss and that the orange angle guide is perpendicular to the top plate (alternatively, check to ensure that the bubble is visible in the level window).
Drive SDWC screw through the top plates and into the rafter/truss.

Installation 3 Instructions — Rafter/Truss Aligned with Stud:
Fasten from Wide Face of Stud
These instructions apply to rafter/truss-to-top-plate connections utilizing one or two screws when installed from the underside of the top plate and from the wide face of the rafter/truss.

Installation Steps: Position the Quik Stik head so that its positioning prongs are in contact with the framing where the top plate meets the wide face of the stud. Sight along the Quik Stik centerline guide to align the tool with the centerline of the rafter/truss. If the rafter/truss is offset from the stud, be sure to install the screw on the overhanging side. Adjust the installation angle of the head to align with the rafter/truss centerline.  For a one screw installation: position the screw in the central one third of thewide face.
For a two-screw installation: see Configuration A on p. 10 for screw locations and edge distances. Drive the SDWC Truss screw through the top plates and into the rafter/truss.
Installation 4 Instructions— Rafter/Truss Aligned with Stud: Fasten from Narrow Face of Stud
These instructions apply if the rafter/truss is aligned wi th the stud belowor if there is blocking directly below the top plate.

Installation Steps: Put the point of the screw in the seam between the top plate and stud — or on the desired spot for installation — and pivot the whole tool up past 45°.

Drive the SDWC Truss screw point into the wood surface so that the first two screw threads embed into the wood. Pivot the tool downward until the bubble appears in the level window, and continue to drive the SDWC Truss screw through the top plates and into the rafter/truss.

Installation 5 — Rafter/Truss Aligned with
Stud: Fasten from Corner of Stud
These instructions apply if the rafter/truss is aligned with the stud below, and the installation of the screw is from the corner where the stud meets the top plate below the rafter/truss. The configuration would be similar to that of Installations 2 and 3.

Installation Steps: Position Quik Stik so the positioning prongs straddle the front corner where the stud meets the top plate. Ensure the centerline guide is pointed at the  center of the rafter/truss.
Align the angle guide with the vertical edge of the stud (or if using the bubble level, the bubble should appear in the level’s window).
Drive the SDWC Truss screw through the top plates and into the rafter/truss until the screw head is flush with the bottom of the top plate.

Two-Screw Configurations

These illustrations apply to rafter/truss-to-top-plate connections utilizing two-screw configurations.
Allow loads using a two-screw configuration per the detail configurations shown on the following pages.

Required| Allowable Loads (lb.)
---|---|---|---|---|---|---
DF/SP| SPF/HF
Uplift| F1| F2| Uplift| F1| F2
A| SDWC15600| 0.152| 6| 5 3⁄4| 2| 1,200| 685| 995| 1,045| 495| 670
B| 1,195| 680| 925| 1,195| 405| 680
C| 905| 535| 790| 850| 330| 595

1. Loads have been increased for wind and earthquake loading (CD=1.6) with no further increase allowed; reduce where other loads govern.
2. For Uplift Connection Load Path, the Designer shall verify complete continuity of the uplift load path.
3. When cross-grain tension cannot be avoided, supplemental reinforcement shall be considered by the Designer.
4. Proper installation angles for all configurations are the responsibility of the installer.
5. SDWC screws must be offset min. 1/4″ from top plate splices for full values.
6. Loads assume minimum overhang of 3 1⁄2″.
7. When a screw is loaded simultaneously in more than one direction, the allowable load must be evaluated using the unity equation: (Design Uplift ÷ Allowable Uplift) + (Design F1 ÷ Allowable F1) + (Design F2÷ Allowable F2) ≤ 1.0. The three terms in the unity equation represent the possible generated force directions. The number of terms that must be considered for simultaneous loading is the sole discretion of the Designer and depends on the method of calculating wind forces and the utilization of the screws within the structural system.
8. An SDWC screw may be used in each ply of two- or three-ply rafters or trusses. The allowable uplift load for each screw shall be multiplied by 0.90, but may be limited by the capacity of the plate or the connection between the top plate to the framing below. SDWC screws in multi-ply assemblies must be spaced a minimum of 1 1⁄2″ o.c.

Raising the Bar on Overhead Fastening

Installations with the Strong-Drive® SDWC TRUSS Screw

Building codes require structures to be designed to create a continuous load path. Forces must be transferred from their point of origin to the building elements that are designed to resist them. When uplift forces act on a roof, the roof must be tied to the wall below it; and the wall must be tied down to the foundation or wall below.
Like hurricane ties, the SDWC truss screw fastens the rafter or truss directly to the top plate of the wall. See pp. 5–15 of this guide for installation requirements and load transfer capacities. The wall top plate alone does not offer sufficient resistance to roof uplift forces, and therefore must be tied to the studs or framing below. The Simpson Strong-Tie Quik Stik allows for fast, easy overhead installation of SDWC Truss screws in rafter and truss assemblies.

Note: In the following pages, truss plate applications have been simplified to improve illustration clarity. Fastener installations are not intended to replace diaphragm boundary members. Designed details to prevent cross-grain bending and cross-grain tension may be necessary.
