SPAX Screws | 8mm T40 Washer Head Screws with Partial Thread in Delta Seal

BENEFITS

Higher tightening torques compared to countersunk head screw

Fastening of slats & squared timbers (e.g. secure fastening of roof battens)

PARTIAL THREAD

In principle, all of screws can be organised into two groups: screws with partial thread and screws with full thread. Screws with partial thread are ideal for fastening components like engineered wood boards, panels, floorboards and even squared timbers on load-bearing components like stud framing or posts. While the thread makes its way through the load-bearing component, the thread-free shank of the partial thread screw should pull all the way through the top attachment. 

DELTA SEAL

Exceeds the corrosion protection when compared with class 4 hot-dipped galvanised products*

Ideal for use in CCA, ACQ and LOSP treated timbers

Free of chrome(IV) so more environmentally friendly than traditional coatings

Includes a glidecoat lubricant coating for reduced torque during installation

WASHER HEAD SCREWS

Higher tightening torques compared to countersunk head screw

Fastening of slats & squared timbers (e.g. secure fastening of roof battens)

Significantly reduced screwing-in torque and lower splitting
