Cembre 2170350 A2-M16 non-insulated tin-plated copper compression ring terminal for terminating 10 mm² copper conductors onto M16 studs.
£8.16
The Cembre 2170350, also designated as the Cembre A2-M16, is a high-quality non-insulated copper compression ring terminal designed to terminate 10 mm² copper conductors onto M16 threaded studs. As part of the established Cembre A-M copper tube terminal series, it provides a secure, low-resistance connection for industrial control panels, switchgear, power distribution equipment and electrical machinery.
Manufactured from high-purity electrolytic copper tube, the terminal delivers excellent electrical conductivity and mechanical strength. Its annealed construction provides the ductility required to withstand compression during crimping, while the electrolytic tin-plated surface helps protect the copper against oxidation and corrosion.
With a 10 mm² nominal conductor capacity and an M16 ring connection, the Cembre 2170350 is suitable for larger studs, bolts and equipment terminals. The chamfered barrel entry simplifies conductor insertion, while the integrated inspection hole allows installers to confirm correct cable positioning before completing the crimp.
Compression ring terminals create permanent electrical connections by mechanically compressing the terminal barrel around the conductor strands. A correctly completed crimp provides excellent electrical continuity, strong pull-out resistance and dependable performance in installations exposed to vibration, temperature changes and continuous electrical loads.
The Cembre A-M series is engineered for electrical contractors, panel builders and industrial engineers who require repeatable termination quality. Its annealed copper construction, chamfered entry and inspection hole simplify installation while helping ensure secure and consistent connections when used with a compatible professional crimping tool and die.

The Cembre 2170350 is used to terminate 10 mm² copper conductors onto M16 threaded studs, creating a secure compression-crimped electrical connection.
The terminal is designed for 10 mm² flexible and low-stranded copper conductors, equivalent to approximately 8 AWG.
The Cembre 2170350 is designed for M16 studs and bolts used on industrial electrical equipment, busbars and distribution assemblies.
The electrolytic tin-plated finish helps protect the copper terminal against oxidation and corrosion while maintaining excellent electrical conductivity.
The conductor should be stripped to the recommended length, inserted fully into the barrel and crimped using a compatible professional compression tool and the correct die for a 10 mm² conductor.
Cembre A-M copper compression terminals are widely used by electrical contractors, panel builders and industrial engineers to create secure, conductive and mechanically reliable cable terminations.
