RA 715-016

Frequently Asked Questions

Q: What are the complete specifications for the RA 715-016 set screw?
A: The RA 715-016 is an OEM set screw with these specifications: 10-32 UNF fine thread, 1/2 inch length, self-locking design, plain finish. It is compatible with Raymond electric lift truck models 50, 51, 60, and 20 (812) series.

Q: What does 10-32 UNF thread mean?
A: 10-32 UNF indicates a number 10 (0.19 inch diameter) fastener with 32 threads per inch in the UNF (Unified National Fine) thread standard. Fine thread provides higher clamping force than coarse thread and is less prone to vibration loosening.

Q: What does self-locking design mean on the RA 715-016?
A: Self-locking design means the screw has a built-in locking mechanism (typically a nylon insert or deformed thread section) that prevents the fastener from loosening due to vibration. This reduces the need for additional lock washers or thread-locking compound.

Q: Which Raymond lift truck models use the RA 715-016 set screw?
A: The RA 715-016 is compatible with Raymond electric lift truck models 50, 51, 60, and 20 (812) series. Verify your specific model and serial number before ordering to confirm compatibility.

Q: Can the RA 715-016 self-locking feature be reused after removal?
A: Self-locking screws typically cannot be effectively reused. The nylon insert or locking thread deformation loses its gripping property after the first removal. Replace with a new OEM RA 715-016 screw on reassembly.

Q: What is the plain finish on the RA 715-016?
A: Plain finish means no plating or protective coating is applied to the screw. The fastener is made from steel in its natural state. For outdoor or high-moisture environments, inspect regularly for corrosion.
