Description
Overview:
The Blue 10mm (3/8") Ring Terminal is a pre‐insulated electrical connector for making strong, low‐resistance terminations to a stud or screw. The blue sleeve provides clear circuit identification and helps prevent short circuits by insulating the crimped joint. The metal ring and barrel are designed for dependable grip on stranded copper conductors when crimped with a suitable tool. Commonly used on plant, agricultural and garden machinery, generators, compressors, pumps and service vehicles, it suits general repairs and new installations alike. The 10 mm ring size fits M10 hardware, while 3/8 in is approximately 9.5 mm for reference. Supplied as a pack of 100 for workshop or site stock. Manufacturer Part Number (MPN): 205 139.
