Taiss M5 T-Nut and Socket Screw Kit for 2020 Aluminum Extrusions

Choosing hardware for an extrusion build means matching the fasteners to the profile and having useful screw lengths on hand. This Taiss kit is made for 2020 series aluminum extrusion and uses M5 T-slot nuts with matching socket screws.

Four screw lengths—M5×8, M5×12, M5×16, and M5×20 mm—give you options for different assembly points. The included hex wrench is suited to the socket heads.

Use the assortment for projects such as 3D printers, CNC routers, laser cutting machines, robotics, and other DIY builds that use 2020 aluminum profile. The nuts and screws are packaged in a plastic box for sorting and access.

Tips for day-to-day use

Choose a screw length that suits the joint and the parts being fastened, then engage the T-nut in the profile slot before tightening with the hex wrench. Keeping the four lengths organized in the supplied box makes it easier to select the right fastener during assembly or maintenance. This is practical for projects with multiple frame connections, where screw length may vary from one mounting point to another.

The kit is intended for 2020 series aluminum extrusion hardware. Before starting a build or replacement, match the M5 fasteners to the profile and connection you are working with. Its mix of lengths supports varied assembly needs within that format, from compact joints to connections requiring a longer screw.

Benefits

The hammer-head T-slot nuts are designed to sit in an extrusion slot, providing a fastening point for compatible M5 screws. This makes the assortment useful when adding or repositioning components on a 2020 frame, including in 3D printer, CNC, and robotics projects. The hex socket head style allows tightening with the included M5 hex wrench.

The nuts are nickel-plated carbon steel, and the socket screws are made from 10.9-grade alloy steel. Having both fastener types together, in four screw lengths, provides a ready assortment for assembly work and later hardware replacement. Buyers have praised the kit’s functionality and said it matches its description, some also mention smooth threading without cross-threading issues. These are customer impressions, not a substitute for matching the fasteners to the application.

Worth noting

This is an M5 fastener assortment for 2020 series aluminum profile, rather than a general-purpose mix of screws and nuts. The included screw lengths are 8, 12, 16, and 20 mm. Nuts and screws come in a transparent plastic storage box, which helps keep the sizes together between build sessions. It makes sense if you are assembling or maintaining a compatible extrusion project and want several screw lengths in one kit.
