Rok-It Bore Gauges

The industry benchmark for internal diameter measurement. Self-centring, self-aligning, and accurate to ±0.001mm.

No discernible friction — gauge "size for size" without rejecting good components
No jamming or swelling in the bore
Self-centring and self-aligning — no struggle for alignment
Fast and simple: GO rocks over centre, NOGO stops = bore is in tolerance
Exceptional gauge life — less friction means less wear
Instantly reveals ovality, barrelling, and taper
80% lighter than conventional plug gauges
Manufactured to BS 969, DIN 7164, and ANSI B89.1.5 standards
UKAS and in-house certification available
