Metallics JFSC1434 Screw 1/4-20 x 3/4 SHCS FH St-Blk (Jar 100)

Yes. The JFSC1434 is a flat head socket cap screw, so the conical head seats into an 82 degree countersink and finishes flush with the surface. It drives with a hex key rather than a slot or Phillips, which is what lets you pull it tight with the head buried. If you need the head to bear on top of the material instead, a button or standard socket cap head is the one to order.

Steel with a black finish. That is a dry, non-plated-looking black oxide style appearance typical of socket screws, so it is intended for indoor and dry locations. For wet, outdoor, or corrosive runs, specify a stainless or zinc plated fastener instead.

Each jar holds 100 pieces of the 1/4-20 x 3/4 flat socket head screw. The jar pack is the shop and service-truck quantity, so it suits an electrical or maintenance crew stocking a common fastener size rather than a single-job buy.

It is stocked as an electrical fastener, and 1/4-20 is the thread used throughout electrical work for channel nuts, enclosure mounting and bracketry. The flat socket head is the one to pick where the screw has to sit flush, for example in a countersunk plate or where a cover or panel passes over the fastener. For strut channel nuts that need a bearing head on top of the channel, a hex head or standard socket cap is the usual choice.
