The 0.5-inch Modular 3-Way Cube with 3 countersunk holes is designed for applications where tubes need to be fixed without rotation. It features three countersunk clearance holes that allow countersunk 10-32 flat-head screws to pass through the cube and secure into threaded inserts in the mating tubes. Each fastener is inserted through an access hole on the opposite face of the cube and rests against an internal surface inside the cube. After assembly, the access holes can be covered with the included plastic snap covers for a clean, professional appearance.
In the image below, the cube is shown in a typical 90° corner configuration. Tubes are fixed in place using internal fasteners accessed from the rear, with clean visible surfaces on all exposed sides.
The cross-sectional rendering illustrates how the fastener enters from one face and sits flush against an internal stop. The opposing access hole is aligned for driver tool entry and capped with a removable snap plug after assembly.
Combine the 0.5” Modular 3-Way Cube with three 0.5" Short Threaded End Connectors to form strong and easy-to-assemble corners, as shown in the pictures below.
Explore our other Cube Connectors to create a variety of easy-to-assemble cube and prismatic shapes. This frame creation system ensures that each tube member is connected at one end by a Modular End Stud Connector (short stud) and at the other end by a countersunk, flat-head screw threaded into a Modular End Thread Connector. Using a countersunk flat-head screw ensures that cubes on either end of a tube member can be aligned parallel to each other. Simply loosen the screw to allow for rotational adjustment, then tighten it again to lock the cube in place.
Constructed from 6061-T6 aluminum with a black anodized finish, the cube balances strength, light weight, and corrosion resistance. Whether you're building a modular test fixture, aerospace frame, or robotic enclosure, this cube simplifies assembly while providing robust structural performance.
