Steel Square-Head Cup-Point Set Screws
Use these set screws for light duty holding. A square head allows them to be turned by hand, or fastened with a wrench when you need more torque. The cup point has a thin edge that digs into the contact surface for a secure hold. Length is measured from under the head.
