Metallics TEL1224BLKV 12-24 x 5/8 in. Pan Head Tri-Drive Telecom Cabinet Screws - Black Oxide - Each

The pan head is tri-drive, so it takes a Phillips bit, a square (Robertson) bit, or a flat blade for the slot. Handy in a cabinet where you can only get one bit in there, and it means a tech with either a Phillips or a square driver can service the rack.

At 5/8 in. of 12-24 thread, these screws carry panel ears, cable managers, shelves, and blanking panels through the rail flange. For stacking thick washers or doubled-up brackets you may run short of thread engagement, in which case step up to a longer 12-24 screw.

Black oxide gives a low-sheen dark finish that disappears against black rack rails and painted cabinet frames, which is why it is the usual choice in a telecom room. It is a light surface coating, not a plating with sacrificial corrosion protection, so keep these indoors in a conditioned equipment room rather than outdoors or in a wet environment.

TEL1224BLKV is the 12-24 x 5/8 in. pan head tri-drive telecom cabinet screw in black oxide, sold in a 500 piece quantity, and it is made in the USA. One model number, so there is nothing else to specify when you order.

Cup washers are not part of the TEL1224BLKV screw and are ordered separately. The pan head seats flat on its own against a rack ear, so a washer is optional and mostly used to protect painted or anodized panel faces from marking. Order them as a separate line if you want them.
