The small cylinder head, of this 5.0 x 40mm decking screw, pulls flush into the wood with a low splitting effect and provides the perfect appearance.
Fixing thread permanently attaches the cover board to the substructure and minimises creaking. Together with the plain shank it pulls the top board down tight (vice effect)
Spax cut point helps precision placement, allows screwing in without pre-drilling (wood-dependent), effectively reduces splitting and bulging of the wood
