What type of screws should i use?

Need to install my l7 in a box. Any specific kind of screws i should use/not use.

just secure it good, i used sheet metal screws, and i tightened them in there really nice

If there is enough room away from the edge, I use machine screws and T-nuts. Most hardware stores have them in the upholstery section. (or check wherever they sell vinyl,foam,leather,etc.)

thanks
