GRK Fasteners: R4 Counter Sinking Screws

Multi Purpose ScrewsThe R4 screw with countersinking cutters creates its own countersink hole and can be used for any material without pre-countersinking.

 

The screw has 6 cutting pockets which also work as supporting edges for the head. When using the screw the cutting pockets create the countersinking and cut into the material. At the same time the supporting edges have a stabilizing effect. When fastening fittings, these supporting edges rest on the pre-formed countersunk holes and avoid material damage.

 

  • The six self countersinking cutting pockets act like a circular saw blade.

  • They transport the "drill-dust" away from the edge of the screw hole.

  • They also widen the countersink hole only around the head shape.

  • The screw head top closes the hole exactly leaving no damaged fibers around the head.

 

The countersink cutting screw can be used in all woodworking and plastic applications and because the head is 90 degrees angle at the underside, the screw fits perfectly into the pre-countersunk holes of hardware fittings such as hinges or locks. Stocking of different screws is no longer necessary. It makes the R4 a very versatile screw.

 

The countersinking gets even better the harder the material. No build up occurs around the countersinking area as the ribs push abraded material away from below the screw head and the material can be compacted tightly together into the space between the cutting-edges.
