T-Slot Fasteners and Hardware Metric

A T-nut block is a specific, often more robust or block-shaped, type of T-nut. Used with T-slot aluminum extrusions. it slides into the channel to provide a secure, internal female thread for attaching components with bolts.

A T-nut is a specialized fastener shaped like a "T" that creates a threaded connection point within T-slot aluminum extrusions. It slides into the extrusion's channel and locks in place, providing a secure, adjustable female thread for attaching components with bolts.

An anchor fastener for T-slot profiles is a strong, internal connector designed to create clean, flush, and vibration-resistant 90-degree joints. It typically involves a screw, cam, and T-nut, and requires a counterbore to be machined into the end of one profile for installation. This allows for a very robust connection that's hidden from view.

Brackets are essential, externally mounted fasteners for T-slot aluminum extrusion structures. They provide strong, highly versatile 90-degree connections, and sometimes even more complex joints. A major benefit of most 80/20 brackets is that they don't require any machining on the profiles, making them exceptionally quick and easy to install, adjust, and reconfigure. You secure them by simply inserting T-nuts into the T-slots and bolting the bracket into place.

Connectors come in various forms to suit different needs. Central connectors, for instance, are used to join to the center face of another profile. Miter connectors specialize in creating hidden angled joints, often at 45 degrees. Bolt connectors are internal fasteners that primarily use a threaded bolt for secure attachment. Whether you need a hidden central connection, a clean angled joint, or a general internal attachment, these specialized connectors, sometimes aided by milling, enable versatile and aesthetically pleasing structural designs.

End fasteners are internal connectors used to create clean, hidden, 90-degree joints where the end of one T-slot profile meets the face of another. They consist of a screw and a specialized wing clip, and their installation requires machining both profiles: an end tap on the "mounting" profile and an access hole on the "mating" profile. These fasteners provide a strong, anti-rotation connection suitable for many applications where aesthetics are important.

Flat joining plates are external fasteners used to connect T-slot aluminum profiles. They are flat metal plates with pre-drilled holes that bolt onto the outside surfaces of profiles using T-nuts. These versatile plates are ideal for creating straight, T-shaped, or corner connections, and a major benefit is they don't require any machining on the profiles, allowing for easy installation, adjustment, and reinforcement of structures.

Inside corner connectors for T-slot aluminum extrusions are internal fasteners that create clean, hidden 90-degree joints. Unlike external brackets, these connectors are concealed within the profiles, offering a sleek look without protrusions. Many standard inside corner connectors can be installed quickly without any special preparation, simply by sliding them into the T-slots and tightening set screws. This makes them ideal for building professional-looking frames and enclosures.

Aluminum framing system screws are various types of socket head cap screws (SHCS) and button head cap screws (BHCS). These are favored for their strength, compact head design, and hex (Allen) drive, which allows for good torque and flush mounting.
