+86-13503272331EMT set screw connector is a common electrical fitting used to securely join lengths of Electrical Metallic Tubing (EMT) to electrical boxes or enclosures. It consists of a body that slips over the end of the conduit. Tightening its built-in screws creates a strong mechanical bond by biting into the EMT wall. Its primary role is to establish and maintain a solid, electrically continuous, and grounded connection, which is crucial for safety and system integrity. This simple, reliable, and cost-effective connector is a fundamental component in commercial and industrial electrical installations.

EMT set screw connector joins electrical metallic tubing to an enclosure or another conduit section. Its working principle relies on mechanical compression and grounding. The installer inserts the EMT into the connector's body. Tightening one or two set screws (grub screws) drives the screw's pointed end directly into the EMT's wall.
This action creates a:
Mechanical Grip: The screw deforms the metal, pinning the conduit securely to prevent pull-out.
Electrical Bond: The metal-to-metal contact establishes a continuous grounding path, which is critical for safety.
The EMT Set Screw Connector features a simple, robust zinc-plated steel body for durability and reliable performance in various electrical installations, ensuring long-term use.
Its key feature is one or two hardened steel set screws. These screws are tightened to bite into the EMT, creating a strong mechanical grip that secures the conduit.
A major advantage is its built-in insulating liner. This critical safety feature protects wire insulation from abrasion against the sharp connector and conduit edges, preventing damage.
This type of EMT Set Screw Connector is highly cost-effective. It offers a reliable, code-compliant connection method while being one of the most affordable options available on the market.
Installation is quick and requires no special tools, just a hex key. This ease of use makes the EMT Set Screw Connector a favorite for time-efficient projects.
Its design ensures excellent electrical continuity for grounding. The metal-to-metal contact between the connector, locknut, and box provides a solid bond for safety.
