Does anyone know if there is more than one size of uniloc pin? I purchased an insert for a shaft from Atlas, and just being diligent I tried it on the butt pin before I was about to set it in the shaft and it wouldn't fit over the pin. It did however, fit over another uniloc pin in comparing the pins side by side you could clearly see one pin was bigger. Oddly enough though the threads seem to be the same size as the same joint protector fits on both. Can I drill out the insert to a tiny bit larger size so it fits? Anyone else have this experience? Solution? anyone? Thanks
