PQR Nuts Bolt Centring Tools 5 Pack

The original set of PQR Nuts consists of 5 standard metric sizes M16, M20, M24, M30 & M36, for surveying of bolts most often used on construction sites.

PQR Nuts can either be used directly in bolt pickups and setout surveys, or used for marking of bolt centres prior to surveying.

PQR Nuts combine efficiency with consistent accuracy in the field.
