Type: Single-hole copper cable lug / palm lug
Cable size / nominal conductor area: 25 mm²
Stud size / Hole diameter: 10 mm (“F10”)
Material: High conductivity copper, often tin-plated to resist corrosion
Stranding: e.g. 19 strands × 1.35 mm diameter typical for 25 mm² conductor sizes
Inner diameter of lug barrel (ID): ~ 7.1 mm
Surface finish: Usually bare copper or tin coated copper for better oxidation resistance
Operating temperature range: approximately -55 °C to +150 °C for many copper cable lugs of this type
