150 Pieces Ring Lug Eyelet Copper Crimp Terminal Assortment — Non‑Insulated (M3, M4, M5, M6, M8, M10) A practical assortment of non‑insulated copper ring lugs for creating secure, low‑resistance connections on bolts and studs. This kit provides a range of common ring sizes (M3, M4, M5, M6, M8, M10) to match standard fasteners and terminals, making it easy to finish wiring for automotive, industrial, household, and DIY projects. Key benefits Reliable electrical contact: Solid copper construction offers good conductivity for dependable connections. Versatile compatibility: Ring sizes M3–M10 fit standard screws, bolts and studs used in equipment, panels and vehicles. Time‑saving organization: An assortment of 150 pieces reduces the need to source individual terminals for different fasteners. Durable, serviceable design: Non‑insulated eyelets are compact and appropriate where insulation is not required or where heat/space constraints exist. Features and specifications Material: Copper Type: Ring lug / eyelet crimp terminal Insulation: Non‑insulated Ring sizes included: M3, M4, M5, M6, M8, M10 Quantity: 150 pieces total (assortment) Functionality and performance Designed to be crimped onto stripped cable or wire to form a solid mechanical and electrical connection to a bolt or stud. Non‑insulated style provides a direct metal‑to‑metal contact and is suitable for applications where insulation is not required or where additional protective measures (heat‑shrink tubing, conduit, or terminal blocks) are used. Copper body supports reliable conductivity and corrosion resistance typical for general electrical use. Suggested use cases Automotive battery and chassis connections: Securely fasten battery leads, grounding straps and accessory feeds to chassis or battery terminals using the appropriate ring size. Electrical panels and machinery: Terminate control wiring and power conductors for connection to terminal studs, bus bars and equipment bolts. Home and DIY electrical work: worn lugs, create tidy splices, or prepare wires for fastening to switches, relays and connectors. Practical tips Use a proper crimping tool sized for copper ring terminals to ensure a secure mechanical and electrical connection. Because these are non‑insulated, consider using heat‑shrink tubing, protective sleeving, or placement inside enclosures to prevent accidental shorts where needed. Verify bolt/stud size before selecting the ring lug (M3–M10) for a correct fit. What's included Assortment kit of 150 non‑insulated copper ring lug eyelet crimp terminals covering M3, M4, M5, M6, M8 and M10 ring sizes. This assortment is ideal for technicians, hobbyists and installers who need a reliable, compact selection of copper ring lugs for a wide range of fastening sizes.
