SIMPSON STRONG-TIE STRONG-DRIVEŽ SCREW (SDS) 1/4 X 2 (1PK OF 250)

Bulk Pack of 250
The Simpson Strong-DriveŽ screw (SDS) is a 1/4" diameter structural wood screw ideal for various connector installations as well as wood-to-wood applications. It installs with no predrilling and has been extensively tested in various applications. The new SDS is improved with a patented new easy driving 4CUT™ tip and a corrosion resistant double-barrier coating.




The patented 4CUT tip has a square core and serrated threads to reduce installation torque and make driving easier with no predrilling and minimal wood splitting.
A new double-barrier coating finish provides corrosion resistance superior to hot-dip galvanization. Now one screw can handle interior, exterior and certain pressure-treated wood applications. See Corrosion Information.
3/8" hex washer head is stamped with the No-Equal sign and fastener length for easy indentification after installation.



Allowable loads for SDS screws are based on ICC-ES Code Report ESR-2236. Screws may be provided with the 4CUT or Type 17 tip.
SDS screws install best with a low speed 1/2" drill with a 3/8" hex head driver.
Wood to wood applications are based on a wood thickness of 1 1/2" side member.


All applications are based on full penetration into the main member. Contact Simpson for allowable loads for other side member thicknesses.


Allowable loads are shown at the wood load duration factor of CD=1.00. Loads may be increased for load duration by the building code up to a CD=1.60.


Withdrawal loads shown are in pounds (lbs.) and are based on the entire threaded section installed into the main member. If thread penetration into the main member is less than the Thread Length as shown in the table, reduce allowable load by 172 lbs. x inches of thread not in main member. Use 121 lbs./inch for SPF.


DO NOT USE SD8x1.25 wood screws with structural connectors unless specifically stated in this catalog.
SD8 requires 3/4" minimum penetration.
