What Are The 15-5 PH Nuts
15-5 PH Nuts are nearly typically employed in opposition to a mating bolt. The bolt’s small stretch, the friction between the two partners’ threads, and the compression of the parts work together to keep the two partners joined.
Different locking systems, such as adhesives, safety pins or lock wire, nylon inserts, or threads with a slightly oval shape, may be used in situations where vibration or rotation could cause a nut to come loose.
For identical reasons as the bolt head, the most popular shape is hexagonal. Six sides provide a good granularity of angles for a tool to approach from corners that would be susceptible to being rounded off. For specific purposes, there are other specialty forms available, such as wing 15-5 PH Nuts for finger adjustment and captive nuts for difficult-to-reach places.
Applications
As an example, an ISO property class 10 nut will be able to handle the bolt-proof strength load of an ISO property class 10.9 bolts without stripping. 15-5 PH Nuts are graded with strength ratings suitable to their associated bolts.
The proof load of an SAE class 5 bolt can also be supported by SAE class 5 nuts, and so on. There are many different types of nuts, ranging from ordinary hardware variants to specialty designs made for particular industries and designed to suit particular technological requirements.
Benefits Of 15-5 PH Nuts
- Higher creep stress and rupture properties when compared with 304
- Ideal for high-temperature service
- Overcomes sensitization and intergranular corrosion concerns
- Can be used in elevated temperature applications for ASME Boiler and Pressure Vessel Code applications
- Due to stabilization, the material offers better overall corrosion resistance when compared to 304/304L
- Excellent mechanical properties
