■ Characteristics Since it requires no tapping, the process would be simpler. ■ Notes • Measure the L dimension and adjust the counterbore depth of installation hole. • Installation should be done by inserting into the hole and attach with adhesive. (Do not press–fit because caulking section will be deformed and cause operation failure.)
15.7 16 E M2/M3/M4 have no groove for the specific wrench (BPJG). so that they can only be installed in hexagonal holes. Moreover they are not applied with loosening prevention treatment. For M5 or higher, use the specific wrench. E The anti–loosening effect can be maximized by leaving the product at 25°C for at least 72 hours. Please note that the anti–loosening effect will be reduced if the product is left at low temperature for a short time. E ＊ M2 is only available for BPJ/BSZ. E Load values "min." indicate an initial load, and "max." a load when the ball is fully sunk. Load {kgf} = Load N × 0.101972 116.3

Ball M Material
E ＊ There is no relief machining on M4 and M5. Also, there is an incomplete threaded part, so chamfer the tap hole on the mounting side. E Load values "min." indicate an initial load, and "max." a load when the ball is fully sunk.
