We offer three screw diameters: 1/4', 5/16', and 3/8' for 12V48V systems. Key benefits and features Wide compatibility: suitable for automotive circuit modification, power distribution, and industrial equipment wiring. Easy installation: includes standard stainless steel nut and washers; wiring can be completed with a regular wrench, no professional tools required. current capability: each screw withstands continuous current of 50A; features a 20% increase in crosssectional area and a 15% increase in conductivity efficiency compared to ordinary terminal posts, with no heat generation or softening under longterm load operation. Durable and safe construction: the screw nut is stainless steel and less prone to rust in humid environments or when exposed to electrolytes; paired with a flameretardant nylon base, it isolates the risk of electrical leakage and enhances electrical safety. Use scenarios Automotive circuit modification: upgrade battery connections and power distribution points in cars, trucks, or motorcycles to handle higher current with reliable connections. Marine power distribution: shore and onboard wiring in boats or ships where humidity is common, benefiting from rust resistance and leakage isolation. Industrial equipment wiring: main power feeds and distribution blocks in control panels or machinery where durable, current connections are required.
