Stinger SPT828 8GA Grub Screw Gold Ring Terminal

Stinger SPT828 Platinum Series Gold Finish 8 Gauge Allen Set Screw Ring Terminal with 5/16 Inch Ring and Red and Black Polarity Bands

The SPT828 from Stinger is a Platinum series 8 gauge gold finish ring terminal featuring an allen set screw (grub screw) connection for a secure, tool-tightened wire termination. The 5/16 inch ring opening suits standard amplifier, distribution block, and battery terminal stud sizes. Both red and black polarity bands are included, allowing the terminal to be used for either positive or negative applications. Supplied as a single individually packaged unit.

Product overview

The SPT828 uses an allen set screw connection rather than a crimp, securing the wire mechanically via a grub screw tightened with an allen key against the conductor inside the terminal body. This provides a solid, repeatable connection that can be released and re-tightened if the installation changes, without the need for a crimp tool. The gold finish provides both corrosion resistance and a premium custom build aesthetic suited to high-end installations where terminal quality and appearance are part of the overall standard.

The included red and black polarity bands allow the same gold terminal to be identified as either positive or negative by slipping the corresponding band over the terminal body, removing the need to stock separate colour-specific terminals for each polarity. The 5/16 inch ring opening is the standard stud size for car audio distribution blocks, battery terminals, amplifier power connections, and circuit breakers.

Features and benefits

Allen set screw (grub screw) connection: The grub screw tightened with an allen key provides a secure, mechanical hold on the wire that can be released and re-tightened without damaging the terminal, preferred in custom builds for reliability and a clean finished appearance.

Gold finish: The premium gold-plated finish resists corrosion and provides a reliable, low-resistance electrical connection alongside a quality aesthetic suited to custom car audio builds.

5/16 inch ring opening: Suits standard 5/16 inch stud sizes used on amplifiers, distribution blocks, battery terminals, and circuit breakers in car audio installations.

Red and black polarity bands included: Both polarity bands are included in the pack, allowing the same terminal to be used for either positive or negative applications without requiring separate colour-specific terminals.

Individually packaged: Supplied as a single individually packaged unit, suited to single-use applications or as part of a custom terminal selection for a specific build.

Frequently asked questions

What is the difference between an allen set screw terminal and a crimp terminal?
An allen set screw terminal uses a grub screw tightened with an allen key to clamp the wire in place, providing a secure mechanical connection that can be undone and redone without damaging the terminal. A crimp terminal is permanently compressed onto the wire and cannot be reused. Set screw terminals are preferred in custom builds for their clean appearance and the ability to service or reconfigure connections.

Can the SPT828 be used for both positive and negative connections?
Yes. The SPT828 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 colour band to identify the polarity of the connection.

How does the SPT828 compare to the SPT528 set screw ring terminal?
Both are 8 gauge set screw ring terminals with a 5/16 inch ring and included polarity bands. The SPT528 is from the PRO series with a chrome finish, while the SPT828 is from the Platinum series with a gold finish. The gold finish on the SPT828 provides additional corrosion resistance and a premium custom build aesthetic. Select based on the finish that suits your installation standard.

What stud size does the 5/16 inch ring opening fit?
The 5/16 inch ring opening fits standard 5/16 inch studs found on amplifiers, distribution blocks, battery terminals, and circuit breakers used in car audio installations.

Is the SPT828 suitable for 8 AWG wire only?
The SPT828 is designed for 8 gauge wire. Using a significantly larger or smaller gauge wire may result in a poor mechanical or electrical connection. Always match the terminal gauge to the wire gauge used in your installation. Contact us if you need guidance on selecting the correct terminal gauge for your specific cable.
