RA 5-016-005

Frequently Asked Questions

Q: What is the RA 5-016-005 lock nut?
A: The RA 5-016-005 is a nylon insert lock nut with 5/16 inch 18 UNC right-hand threads. It is manufactured from low carbon steel Grade 2 with an engineering-grade nylon locking insert designed to prevent vibration loosening.

Q: Why does the RA 5-016-005 have a nylon insert?
A: The engineering-grade nylon insert creates friction against the bolt threads, preventing the nut from vibrating loose during equipment operation. This self-locking feature eliminates the need for washers or lock washers in most applications.

Q: What equipment uses the RA 5-016-005 lock nut?
A: The RA 5-016-005 is an OEM fastener for Raymond material handling equipment requiring 5/16 inch threaded connections. Verify thread size and equipment compatibility before ordering.

Q: How long does the nylon insert in the RA 5-016-005 last?
A: The nylon insert provides reusable locking for multiple install and removal cycles. However, it will eventually wear out with repeated assembly. Once the nylon insert loses its grip or the nut spins freely on the bolt, replace it with a new RA 5-016-005.

Q: Can I reuse the RA 5-016-005 lock nut multiple times?
A: Yes, the nylon insert can be reused for several installation cycles. However, each removal and reinstallation degrades the nylon slightly. After 5 to 7 reuse cycles or when the nut no longer holds tension reliably, replace it with a new RA 5-016-005.

Q: Is the RA 5-016-005 equivalent to a standard 5/16 inch lock nut?
A: The RA 5-016-005 is OEM-specified for Raymond equipment and meets Grade 2 steel requirements. While other lock nuts may fit the thread size, always use the RA 5-016-005 for original equipment applications to ensure proper tension retention and compatibility with equipment specifications.
