Stinger SPT5108B PRO Series 8 Gauge Black Boot Ring Terminal 25 Pack with Shoc-Krome Platinum Finish and 5/16 Inch Ring The SPT5108B from Stinger is a PRO series 25-pack of 8 gauge black ring terminals with Shoc-Krome platinum finish and a black boot for ground connection identification. It is the bulk ground counterpart to the SPT5108 retail 4-pack, providing workshop stock and multi-amplifier build quantities of correctly sized 8 gauge ground terminals. A crimp tool suitable for 8 gauge terminals is required for installation. Product overview The SPT5108B uses the same crimp-style construction as the SPT5108 retail 4-pack, supplying 25 black boot terminals in bulk for commercial installer use and large-scale builds. The black boot identifies these terminals as negative ground connections by standard automotive wiring convention, and the Shoc-Krome platinum finish provides corrosion resistance across all terminal surfaces for long-term reliability in automotive environments. The 5/16 inch ring hole suits the standard stud size on battery terminals, distribution blocks, and amplifier power connections, making the SPT5108B compatible with the Stinger SPD510, SPD8120, and SPD8124 products listed in this session. The 25-pack quantity ensures a consistent supply of ground terminals for workshop stock or any installation requiring multiple 8 gauge ground terminations. Features and benefits 8 gauge black boot ring terminal: The black boot identifies these as negative ground terminals by convention, designed for crimp connection to 8 gauge ground wire in car audio and accessory installations. Shoc-Krome platinum finish: The Shoc-Krome plating provides corrosion resistance and a premium platinum appearance consistent with the Stinger PRO series range. 5/16 inch ring hole: The 5/16 inch inner ring diameter suits the standard stud size on battery terminals, distribution blocks, and amplifier power connections. 25-pack bulk quantity: The 25-pack suits workshop stock, installer use across multiple vehicles, and large-scale installations requiring a consistent supply of correctly sized 8 gauge ground terminals. Crimp-style construction: Connects via crimp to 8 gauge wire. A crimp tool suitable for 8 gauge terminals is required for correct installation. Technical specs Specification Detail SKU SPT5108B Brand Stinger Series PRO Terminal Type Ring terminal, crimp Wire Gauge 8 AWG (8GA) Ring Size 5/16 inch Plating Shoc-Krome (platinum finish) Boot Black Quantity 25 per pack Frequently asked questions What is the difference between the SPT5108B and the SPT5108?The SPT5108 is a 4-pack retail option containing two red and two black 8 gauge terminals for two complete power and ground connection sets. The SPT5108B is a 25-pack of black terminals only, suited to workshop or commercial installer bulk stock where 8 gauge ground terminations are needed in volume. Is a red 25-pack available for 8 gauge terminals?Only the SPT5108B black 25-pack is confirmed in the available source data. Contact us to confirm whether a red 25-pack equivalent is available for 8 gauge positive power terminations. Do I need a crimp tool to install the SPT5108B terminals?Yes. A crimp tool suitable for 8 gauge terminals is required for correct termination. Contact us if you need guidance on selecting the correct crimping tool for these terminals. What does the 5/16 inch ring size refer to?The 5/16 inch specification refers to the inner diameter of the ring, which is the hole size that slides over the stud or bolt. It is the standard stud size for car audio distribution blocks, battery terminals, and amplifier power connections. Can the SPT5108B terminals be used for positive power connections?Electrically yes, but the black boot colour-coding convention indicates negative ground. For positive power connections, using red-booted 8 gauge terminals is recommended to maintain standard polarity identification throughout the installation.
