XS Power 575 M10 Brass Bolts for 551 I-Bar Bus-Bar Battery Post Terminal Adapter

The 575 is a set of brass post adapters and bolts with M10 threads, made for XP1000 batteries and the 551 I-Bar terminal adapter. Thread size is one of those details that stops an install cold. If your ring terminals, bar, or battery posts use M10 and the hardware in your hands does not, you are either waiting on parts or forcing a fastener that will not hold torque. These adapters and bolts put the connection on the correct thread. Brass is the material that matters here: it carries high current well and holds its dimensions when a fastener is torqued against it, so a terminal that feeds an amplifier rack or an inverter stays tight instead of loosening through heat cycles and building resistance. The larger M10 shank also gives you more clamping surface than a small bolt, which helps on heavy cable with big ring terminals. Practical uses include converting an XP1000 to accept I-Bar accessories, matching cables you have already crimped, and standardizing every terminal in a multi-battery build on the same wrench size.
