Without a head to get in the way, these screws fit in tight spaces where standard shoulder screws cannot. Either thread them in a countersunk hole for a flush mount, or install them with the shoulder sticking out to use them as pins or dowels for aligning and locating components.

These slotted screws have a head height about one-third the head height of a standard shoulder screw. Use them in low-clearance applications such as inside machines.

Designed with a shoulder for the strength to handle side and shear loads.
