Cembre 2170190 A2-M6 non-insulated copper tube crimping lug for terminating 10 mm² stranded copper conductors onto M6 studs.
£0.47
The Cembre 2170190, manufacturer reference A2-M6, is a professional copper tube crimping lug designed to terminate 10 mm² stranded copper conductors onto electrical equipment with an M6 fixing stud. Part of the established Cembre A-M series, this non-insulated ring terminal provides a secure, conductive and mechanically robust cable connection.
Manufactured from high-purity electrolytic copper, the A2-M6 is annealed to provide the ductility required during compression. This helps the lug withstand the substantial deformation created by crimping while reducing the risk of cracking between the barrel and palm. An electrolytic tin-plated finish protects the copper against oxidation and supports dependable long-term electrical performance.
The lug features a chamfered cable entry and inspection hole to assist conductor insertion and allow the installer to confirm that the cable has been fully positioned before crimping. With a 10 mm² conductor capacity, 6.4 mm stud hole and compact 26.5 mm overall length, the Cembre 2170190 is suitable for control panels, distribution equipment, machinery and power cable installations.
Copper tube crimping lugs create permanent electrical terminations by compressing the lug barrel around the conductor with a correctly matched crimping tool and die. A properly completed crimp produces a low-resistance connection with the mechanical strength needed for industrial electrical installations.
The annealed copper construction of the Cembre A2-M6 allows the barrel to deform evenly during crimping. Its tin-plated surface helps prevent oxidation, while the inspection hole and chamfered entry simplify accurate conductor positioning before the termination is completed.

The Cembre 2170190 is used to terminate a 10 mm² stranded copper conductor onto an electrical connection point fitted with an M6 stud.
The product reference is A2-M6, part of the Cembre A-M range of copper tube crimping lugs.
The lug is designed for an M6 fixing stud and has a nominal stud hole diameter of approximately 6.4 mm.
The electrolytic tin-plated finish helps protect the copper surface against oxidation and supports reliable electrical conductivity over the service life of the connection.
The conductor should be stripped, fully inserted into the barrel and compressed using a compatible professional crimping tool and correctly sized die for a 10 mm² conductor.
Cembre A-M copper tube crimping lugs are widely used by panel builders, electrical contractors and industrial engineers for dependable conductor termination in power distribution, machinery and control equipment.
