Thread forming Grease Nipples Grease fittings: The taper angle and thread profile of these fittings are special. Also the threads are hardened. They are designed for use in untapped holes (thus saving cost of tapping). When screwed in, they are meant to cut and form a thread in the untapped hole, resulting in a leak proof fitment. These may also be pressed straight into untapped holes. Worn out or damaged thread forming fittings can be replaced with standard threaded fittings, or by another thread forming thread fitting. Thread forming thread fittings are manufactured as per DIN 71412-1987 and as per SAE -J534 1998 standards. |
