I bought this together with the "5650 Cage Nut M6 Pack" to mount my studio gear. It has the same color as the Rack Strips, so it fits in the design perfectly. It holds, together with the cage nuts, my studio gear together and it's durable (as it's made of steel).
Together with the cage nuts, I'll recommend these inexpensive screws, which will never disappoint you, and never let you (or your equipment) down.
