Description
This is a black socket head set screw sized #4-40 x 3/16" made from steel with a plain black finish, designed for situations where a low-profile, recessed drive is needed. You’ll reach for it when securing small parts in assemblies where a flush or nearly flush fastening is preferred, such as in light fixtures, appliances, cabinetry hardware, model assemblies, or small machinery. The socket head accepts a hex key for controlled tightening, while the USS coarse #4-40 thread offers reliable engagement in common tapped holes and inserts. Its compact 3/16-inch length makes it suited for thin materials and shallow thread depths where a longer fastener would protrude. Durable steel construction provides dependable holding power for repetitive adjustments and maintenance tasks in home and workshop projects.
