The flange head ensures excellent tightening capacity of the joint; the flat shape allows a joint without additional thickness on the wooden surface, thus enabling the fixing of plates on the same element without interference.
The short, fixed-length thread at 1 1/3" (34 mm) is optimised for fastening multi-layer elements (Multi-ply) for lightweight frame construction.
Coated with black E-coating for easy recognition on site and increased corrosion resistance.
TBSF is easily installed without pre-drilling hole. More screws can be used in less space and larger screws in smaller elements.
