QUIK DRIVE FASTENERS AND ATTACHMENTS WSNTL COLLATED SCREW SYSTEM
2" or 2 1⁄2"
Simpson Strong-Tie® Quik Drive auto-feed screw driving systems offer superior performance and reduced installation time in subfloor applications. The holding power of screws reduces the gaps that cause floor squeaks and the tool extension enables stand-up-and-drive installation. CODES: ICC-ES ESR-1472; City of L.A. RR25661; Florida FL 13731

1. Minimum fastener penetration of 11⁄4" into the framing member is required. 2. For wind design, shear capacities may be increased 40% per section 2306.3.2 of the 2006 IBC and 2306.2.1 of the 2009 IBC. 3. For shear loads of normal or permanent load duration as defined by the AF&PA NDS, the values in the table above must be multiplied by 0.63 or 0.56, respectively. 4. The minimum nominal width of framing members not located at boundaries or adjoining panel edges must be 2 inches.
Screws spaced 6 inches, maximum, at support edges6 Case 1 (no unblocked edges or continuous joints parallel to load)

5. Framing at adjoining panel edges must be 3 inches nominal or wider, and screws must be staggered where both of the following conditions are met: (1) screws having penetration into framing of more than 1½ inches and (2) screws are spaced 3 inches o.c. or less. 6. Space screws maximum 12 inches o.c. along intermediate framing members (6 inches o.c. where supports are spaced 48 inches o.c.). 7. Framing at adjoining panel edges must be 3-inch nominal or wider, and screws must be staggered where screws are spaced 2 inches or 2½ inches on center. 8. See ESR-1472, Table 1 for illustrations showing Cases 1 through 6.
9. See ESR-1472 for allowable shear loads for high load diaphragms. 10. WSNTL withdrawal and pull-thru values exceed those for a 10d common nail. 11. See ESR-1472 for high load diaphragm design values.
