Review on 📏 HHIP 4100 0040 Precision Center Line Calipers by Hassan Tomlinson

My set's measurement if it differs by about 0.003 overall. The outer diameter of both is exactly 9.50 mm. The OD offset from the groove is 4.70mm on one and 4.72mm on the other for a total of 0.08mm == 3k runout. Not that bad. Oddly, one of the middle pickups uses a 1.5mm set screw and the other uses a 1/16" set screw. The Allen key provided is 1/16" and will not fit the 1.5mm set screw.,
