Toepassing

Advantages

Countersunk head: ideal for timber/timber or steel/timber assembly with head flush with surface
Underhead ribs: for a clear finish and no timber superficial split
Full asymetrical thread for a maximum withdrawal capacity, allows compressive load bearing
SawTooth^® point: fast start, easy driving, no need for pre-drilling
Torx driven: reduces the wear of the bit

Suitable for

Solid Timber, Glulam timber, CLT, Wood-based panels
Pre-drilled steel plate

When to use

Timber to timber assembly
Steel to timber assembly
Timber reinforcement (to transversile tension or compression)
