Reisser R2 Pozi Woodscrew 5x80mm Tub of 400

In-Depth Look

Splitting is most likely when fixing into hardwood or close to the end of a timber. The Reisser R2 is designed to help with this, and retailers describe split-prevention slots and a sharp needle point.

Head and Point

The countersunk head is made to sit flush with the timber surface. The needle point helps the screw start without wandering. In dense hardwood, thin timber or close to an edge, drill a pilot hole to be safe.

Drive

The Pozi No.2 recess suits a standard Pozi No.2 bit. Using the matching bit, rather than a Phillips bit, reduces cam-out and damaged screw heads.

Summary

A 5 x 80mm countersunk Pozi woodscrew in a tub of 400, with a yellow zinc passivated finish for interior and sheltered use. It is not for exterior work or treated timber.

How It Compares

This tub holds 400 Reisser R2 woodscrews, each 5.0mm in diameter and 80mm long. They have a countersunk head, a Pozi drive and a yellow passivated coating. The tub has a hinged lid, and the screws are part of the Reisser R2 range.

The label on a screw pack gives two numbers. In 5.0 x 80, the 5.0 is the thickness in millimetres and the 80 is the length.

Common Questions

What does 5.0 x 80 mean? It means 5.0mm thick and 80mm long.

What is Pozi drive and which bit do I use? Pozi is the cross-shaped recess in the head, with extra marks between the arms. Match the bit to the recess, so a Pozi No.2 bit goes in a No.2 recess. Check the pack for the recess size on the screws you have.

What is a countersunk head? A countersunk head is shaped like a cone so that it sits flush with, or just below, the surface of the wood when driven in.

When should I drill a pilot hole? A pilot hole helps in hardwood and near the edge or end of a board, where wood is more likely to split. Check the pack for what the screws are designed to do, and drill a pilot hole when in doubt.

Can I use them outside? Check the pack. A yellow coating is not the same as a coating sold for outdoor use, so confirm the screws are suited to the conditions before using them outside.

Use the correct bit in a driver that suits the screw, and follow the tool maker’s instructions.
