The Stinger SPT528 is a PRO-series 8 gauge ring terminal featuring a 5/16″ ring opening, oversized set screw connection, and a deep wire recess design for a clean, secure wire termination. Finished in chrome, this terminal delivers both a reliable electrical connection and a professional installation appearance exactly what you'd expect from Stinger's PRO terminal range.
One red and one black polarity rubber band are included, allowing the same terminal to be used for either positive or negative applications without purchasing separate terminal types. The oversized set screw provides a firm, tool-tightened mechanical hold on the 8 gauge wire, while the deep wire recess ensures the wire is fully seated and protected within the terminal body. A practical, quality choice for any car audio installer or DIYer looking to terminate 8 gauge power or ground cable with a clean, professional result.

How does the SPT528 differ from the Stinger SPT828?
Both are 8 gauge 5/16″ ring terminals with set screw connections and red/black polarity bands. The SPT528 has a chrome finish while the SPT828 has a gold finish. The SPT528 also features a specifically noted deep wire recess design. Choose based on your preferred finish for your build.
What does the deep wire recess do?
The deep wire recess ensures the 8 gauge wire is fully inserted and seated within the terminal body before the set screw is tightened. This provides a more secure mechanical connection and a cleaner, more professional termination compared to shallow-recess terminals.
Can this terminal be used for both positive and negative connections?
Yes the SPT528 includes both a red and a black polarity rubber band, allowing the same terminal to be used for either positive or negative applications. Fit the appropriate band to identify the polarity of the connection.
What stud size does the 5/16″ ring opening fit?
The 5/16″ ring opening suits standard 5/16″ studs commonly found on amplifiers, distribution blocks, battery terminals, and circuit breakers used in car audio installations.
