Simpson Strong-Tie

The LDSS light diaphragm spline strap is designed to be placed directly on top of CLT and other mass timber panels. Unlike plywood splines, the LDSS does not require routing. As part of the Simpson Strong-Tie® complete LDSS spline solution, the steel strap installs easily and safely using our PRO300SG2 Quik Drive® tool and collated Strong-Drive® WSV Subfloor screws. The LDSS features an innovative embossed hole design that helps guide the installation tool and increase fastener capacity.

Computer modeling and CNC manufacturing enables glulam to be delivered to the jobsite in precise lengths and with preinstalled concealed hangers. The CBH concealed beam hanger is specifically designed for such applications, and is installed with readily available Simpson Strong-Tie® SDS Heavy-Duty Connector screws. The CBH has been tested for inter-story drift and has achieved 1-hr and 2-hr fire resistance ratings according to ASTM E119.

The Strong-Drive SDCF Timber-CF screw is a structural fastener available in a variety of lengths and is designed for cross-laminated timber (CLT), mass timber construction and general interior applications. These 0.315"- and 0.390"-diameter structural fasteners provide uncompromised strength for these demanding applications. The large flat head with underhead nibs provides for clean countersinking. The yellow zinc, fully-threaded screw, with a proprietary unique point, provides fast starts with no predrilling and excellent withdrawal and shear resistance. For interior and dry applications only.
