Sta-Kon RA18-516 Ring Terminal 5/16 in Stud

This Sta-Kon ring terminal connects 16 AWG copper conductors to a 5/16 inch stud. It features a red nylon insulation with partial coverage and a serrated barrel for a secure crimp termination. The terminal is rated for 600 V and carries CSA and UL certifications.

Suitable for 16 AWG wiring on 5/16 inch studs.

Builders terminating 16 AWG copper wire on a 5/16 inch stud will find this terminal fits the barrel and stud size. Those needing to connect thicker gauges or different stud diameters must select a different part. The partial nylon insulation suits standard crimp applications.

16 AWG maximum wire size decides fit

The barrel accepts a maximum wire size of 16 AWG and a minimum of 22 AWG, so the conductor must fall within this range. A 5/16 inch stud matches the terminal hole spacing of 0.31 in. Verify your wire gauge and stud size before purchasing.

Questions about this item

What stud size and hole spacing does the 5/16 in ring terminal need?

It fits a 5/16 in stud with 0.31 in hole spacing, and the 0.46 in tongue width clears the mounting surface.

How do I crimp the serrated barrel on 16 AWG wire, and what mistake should I avoid?

Use a ratchet crimper matched to 16 AWG; the common error is using pliers, which leaves the serrated barrel loose on the copper conductor.

When should I replace the terminal if it runs near the 221 °F limit?

Inspect the red nylon insulation for cracking or discoloration; replace the terminal if the tin-plated copper barrel shows corrosion or the crimp feels loose.
