Quik Drive 34mm Underlayment (Box 2500) Quikdrive Part No. MTH32E

The MTH underlayment screw is designed
for fast and secure underlayment to subfloor installations. Unlike
nails, the MTH underlayment screw has an intricate high-low thread
pattern designed to prevent squeaking by holding underlayment tight to
the subfloor and thus preventing withdrawal. Its countersunk compact
trim-head allows for a flush surface finish and prevents floor coverings
from settling in countersink recesses. CE marked to EN14592.

MTH is a ribbed head screw with sharp point suitable for plywood, chipboard and OSB to wood installations, such as flooring.
