Item Description

The redesigned Simpson Strong-Tie Strong-Drive SDCF Timber-CF screw is a structural fastener designed for cross-laminated timber (CLT), mass timber construction and general interior applications, providing uncompromised strength for demanding applications. The large flat head with underhead nibs enables clean countersinking and a flush finish. The SawTooth point ensures fast starts, reducing installation torque and eliminating the need for predrilling in most applications. The black e-coat finish enhances aesthetics and, along with the optimized hardness profile, helps mitigate risk of brittle fracture for reliable, long-term performance.

Features:

Flat head with nibs helps countersink the screw for a flush finish
Heavy-duty, fully-threaded shank provides strength, with superb withdrawal resistance
SawTooth point for fast start and easy driving
Black e-coat finish provides a construction-durable nonmetallic coating for corrosion resistance in interior dry-service applications
Deep 6-lobe recess for a secure drive
Compliant with CSA O86:24 hydrogen embrittlement requirements
Length: 17-3/4 in. (450 mm)
Quantity: 25 per package
