Marinco Insulated Stud – Double 8mm (IST8MM2S)
The Marinco IST8MM2S is a double insulated stud terminal designed for high-current marine electrical connections. The extended 8mm stainless steel stud accepts up to three large cable lugs, making it well-suited for consolidating multiple medium-to-heavy-gauge conductors at a single protected termination point. A clear polycarbonate cover provides insulation and protection from accidental contact, while snap-out side skirts allow flexible cable entry from multiple directions.

Parts Desk Insights
Best use case: The IST8MM2S is the right choice when you need a protected, multi-lug termination point for medium-to-heavy-gauge wiring — such as accessory feeds, bilge pump circuits, or secondary distribution runs. The 8mm stud is slightly smaller than the 10mm IST10MM2S, making it better suited to applications where cable sizes are in the 6–16mm² range rather than the largest battery cable gauges. The polycarbonate cover is important in any installation where accidental contact with the stud is a risk. If you need to handle the largest battery cables or windlass leads, consider the 10mm variant instead.
