A post and screw connector is a type of fastener comprised of a barrel-shaped, internally-threaded boss (post) with a protruding flange, paired with a matching machine screw. The post is installed in a drilled hole in the part or surface being fastened, with the flange providing the bearing surface. The corresponding screw installs flush on the opposite side of the hole. Also known as Chicago screws, barrel nuts, or connector bolts, post and screw connectors are a low-profile fastener option.

Jay-Cee Sales & Rivet stocks aluminum posts and accompanying aluminum screws in a variety of lengths and styles, all with 8-32 threads. Our aluminum post and screw fasteners are designed for use in 7/32” holes.

We carry aluminum posts in slotted drive, closed end/no drive, and open end/no drive styles. Posts and post extensions in lengths from 1/8” to 6” are available, making it easy to find the right aluminum Chicago screws for your unique needs.
