Standards for T-slots

To increase their chances of this new standard taking off, Magpul has also made M-Lok free for other companies to use. Magpul’s new M-Lok system uses slots in place of the keyholes. The attachment lugs on M-Lok accessories are t-shaped and bi-directional so they can be placed at the front or rear of the slots.

T-slots come in standard sizes. Needless to say things designed to fit in the T-slots are designed to fit these standard sizes. Similarly, the cutters designed for cutting T-slot are designed to cut standard size T-slots.

• An additional advantage is a stuck key can be removed from a shaft with a hammer blow, the circular profile will push the key out of the slot, as opposed to a standard key which will need to be pushed axially, or pulled out of its slot. Common applications include machine tools, automotive applications, snowblowers and marinepropellers.
