Wood Screws – WS series Fasteners The WS Wood Screw is a self-drilling screw used for numerous framing applications. This screw features a reverse locking serration on the bottom of the screw head to help prevent over tightening against a steel plate. The USP head stamp identifies screws for easy inspection. Screw shear capacities are based on a diameter of 0.242˝ when the shear plane is on the screw shank (SH) and 0.185˝ when the shear plane is on the knurl or threads (T). USP WS Wood Screws have a bending yield strength of 180,000 psi. Materials: Finish: 1/4˝ diameter Grade 5 steel See chart Installation: • Screws are self-drilling. • Install using a low speed clutch drill with 3/8˝ hex head driver. The washer head should be flat to the surface and the serrations will oppose turning and release the clutch. Do not over-tighten the screws. • Installing the screw at an angle may introduce additional bending and tension forces into the fastener if the screw head is not flat on the bearing surface. Care should be given to ensure the fastener is installed perpendicular to the plane of the side plate.

Wood Screw Applications – WS series Joining 2, 3, or 4 Ply Wood Trusses © Copyright 2013 USP Structural Connectors® The installation instructions and design example shown below are intended for a design professional who will be responsible for determining the location and number of wood screws to adequately transfer all loads on the truss. Installation: • Screw spacing shall not be greater than 24˝ on centre and less than 4˝ on centre. However, the location of any individual screw may be adjusted up to one-half the required screw spacing to avoid lumber defects or interference with other hardware. • Load or hanger spacing shall not be greater than 24˝ centre-to-centre. • The last truss ply must have a minimum of 11/4˝ of screw penetration and no more than 1/8˝ gap between each ply. • Screws cannot be installed through metal truss plates unless the Truss Engineer approves predrilling. • On 2x4 members, use one row of wood screws. On 2x6 and 2x8 use two rows, and on 2x10 use three rows. Stagger all rows. • The truss bottom chord shall have lateral bracing installed as called out by the Truss Engineer to prevent any displacement from torsional forces. • Install screws from one side without flipping the truss. • Top and bottom chords require screws and in some cases the webs may require screws. • All lateral bracing should be attached to each truss ply. • Increase edge and end distances if wood splitting occurs. 2 1 /2˝ Min. 1 1 /2˝ Min.
