ALUMINUM SCREW POSTS

Aluminum Screw Posts

The post features an inside thread with a cap at the end. The screw comes with a slot head and threads into the post easily. The posts are approximately 3/16'' in diameter and slide easily into a 1/4'' hole. The screw head is 7/16" in diameter and 1/16" thick. The screw thread is #8-32. We also have extension posts that allow you to increase the posts capacity by extending the length of posts by attaching the extensions between the post and the screw. We offer screw post extensions in 4 sizes 1/4'', 1/2'' 3/4'' and 1'' lengths. All are packaged 100 per box.
