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.

Metric Square-Head Extended-Tip Set Screws
A square head allows you to turn these screws by hand, or use a wrench when you need more torque. Also known as half dog-point set screws, they have a protruding tip that locks within a mating hole or slot to keep parts aligned. Length is measured from under the head.

Square-Head Extended-Tip Set Screws
Use the square head to turn these screws by hand, or use a wrench when you need more torque. Also known as half dog-point set screws, they have a protruding tip that locks within a mating hole or slot to keep parts aligned. Made from alloy steel, they have a black-oxide finish to resist corrosion in dry environments. Length is measured from under the head.
