Conversion kit for 5/8" turnbuckle pin. ø13 mm pin and bushings. Eye/Fork B-MAX: 397 mmImportant note on 5 8" rigging screws Back in 1998 we changed the clevis pin diameter from 13 mm to 15. 8 mm. When upgrading to new rigging screws on a boat built prior to this change, the clevis pin will most likely be bigger than the chain plate hole. The 15. 8 mm clevis pin has to be replaced by one 13 pin and two bushings. This kit includes a 13 mm clevis pin and two stainless bushings.
