4.5 x 50 Reisser R2 Woodscrews Full Thread Yellow CSK (Box Of 200)

Very sharp 25degree point with the thread running to the end allowing immediate starting, no need to pre-start.

The sharp, wide, deep thread penetrates into all timbers WITHOUT a pilot hole, giving exceptional pull-out.

Specifically hardened steel gives the R2 maximum tensile and torsional strength.

The invisible Reisser lubicant helps the screw drive in quickly and easily.

Available in full thread (primarily for board materials) or part thread (primarily for pulling two pieces of timber together tight).

The re-inforced collar under the head gives additional support preventing snapping.

The collar also allows a wide, deep pozi to be inserted. This reduces the risk of the bit jumping out and rounding off the edges.

Each batch checked thoroughly to guarantee 'consistency of quality'.

Yellow tropicalized giving approximately 20 times more rust resistance than standard BZP screws.
