Practical tips for best results
To maximize performance, drive TimberLOK screws straight and steady to maintain the thread engagement. Let the fastener do the work—avoid pounding or forcing from angles that could strip threads. Use the included driver bit to ensure consistent torque and a flush finish, then backfill with appropriate wood sealant or stain to extend the life of outdoor connections. For heavier loads or structural framing, pair TimberLOK with proper joist or header sizing and confirm alignment before installation.
TimberLOK fasteners are the reliable, American-made choice when you need fast, strong, and tidy wood-to-wood connections. Add the FMTLOK04-50 to your toolkit and experience quicker builds, fewer call-backs, and professional-grade results on every project.
