## Description

These side-entry terminal blocks have terminals that hold and release wires through the simple adjustment of a small screw, allowing you to easily make temporary connections to a PCB. Since each terminal has a single corresponding pin spaced every 0.1" (2.54 mm), these terminal blocks can be used with [prototyping boards](https://core-electronics.com.au/prototyping/proto-boards.html) and PCB holes intended for standard 0.1" [male](https://core-electronics.com.au/connectors-sockets/headers.html) and [female headers](https://core-electronics.com.au/connectors-sockets/headers/female-straight.html) (if there is sufficient clearance from nearby components).
