This is a splice joint and is an alternative to scarfing when joining shorter members end to end. Both members in an end lap have one shoulder and one cheek each. Use for:

This hole is stopped 1 ⁄ 4 in (6.4 mm) or so from the edge of the frame member. The second step is to drill a pilot hole concentric with the pocket hole which extends through the edge of the member. The pilot hole allows the screw to pass through the member and into the adjoining member.
