Flat six-lobe recess exterior screw with type 17 point

The screw is with a countersunk head, six-lobed recess, a single lead thread

The shank has a reduced diameter and a chip cavity cut out where the final several threads end at the tip

The deeper thread design offer greater resistance to pull-out forces. The six lobed recess transmits drive torque with less required downward pressure

Made of premium 304 corrosion resistant stainless steel
