Cylinder Head Fully Threaded Self-tapping Wood Screw
The ASSY VG Cyl (Cylinder Head) screw is a fully threaded self-tapping wood screw engineered for timber reinforcement, beam repair, and connections where a small head is required for a clean, concealed, architectural finish. Code-approved reliability, the ASSY VG Cyl screw has been awarded an ICC-ESR approval in the United States and the Canadian Construction Materials Centre Reports (CCMC) approval in Canada.
The range of available lengths and diameters makeS the ASSY VG Cyl suitable for a broad range of projects from log home building to multi-story mass timber construction. The ASSY VG Cyl screw can also be used in beam upgrades and connections where a small screw head is required. ASSY fully threaded screws can be used in typical reinforcing applications, including checked or cracked members, potentially restoring them to nearly their full original strength following our Timber Reinforcement Guide.
