MTW45-8 Mass Timber Angled Washer
Inclined screws greatly increase the strength and stiffness of mass timber connections. The Simpson Strong-Tie® MTW45-8 is designed for use with a wide variety of connection plates and 8 mm-diameter Simpson Strong-Tie Strong-Drive® SDCF Timber-CF screws driven at a 45º angle.
- Recessed hole provides a clean finish with the SDCF countersunk head
- Guides screw to an accurate 45º angle
- High capacity reduces number of screws required in a connection
- Material: ASTM A27, Grade 70–40
- Finish: Galvanized
- Use all specified MTW45-8 washers and Strong-Drive SDCF Timber-CF screws.
- Allowable connector plate thickness is 10 gauge (0.134”) minimum and 1/2" maximum, with minimum specified tensile properties of Fy=33ksi and Fu = 45 ksi.
- Fabricate plates with obround holes as given in the installation images. If plates are galvanized after holes are punched, oversize holes to account for galvanized thickness.
