Internal Six-Lobe Inspection according to ISO 10664 (Sizes T1 to T100)

For the internal inspection of screw heads and profiles, our B2B portfolio offers high-precision ULTRA limit plug gauges according to ISO 10664 in a comprehensive size range from T1 to T100. To reliably account for surface coating processes, two precise designs are available: limit plug gauges for the exact pre-coating size and limit plug gauges for reliable final quality control of the finished size after coating. These robust profile gauges are manufactured from premium, wear-resistant gauge steel to guarantee maximum precision.
