Bench mounted press, manually operated having a stationary base plate with a movable upper ram.

Allows proper shape of metal to form when dies are pressed together. Used to form a bend or flange in the center of a sheet of metal without distortion such as lightning holes or beads in the center of a rib or bulkhead.

Hole in the center of various internal structures that has a flange made around the edge of it to add rigidity to the area. Reduces weight to structural members

Three ways to identify twist drill bits are by?

What are the identifiers for cleco fasteners. Color and size?

Distance from the center of the rivet to the nearest edge of the metal

Minimum edge distance is 2 1/2 times the distance of the rivet the max is 4 times the distance

Minimum edge distance is 2 times the diameter of the rivet from the edge of the metal max is 4 times the Diameter.

When rivets are placed to close sheet metal will crack or pull away from the rivet if to far away the sheet metal will turn up.

Distance between rivets in the same row, and this distance is measured from a rivet center to the next rivet center.

Rivet Spacing is?

Used when two or more rivets are required. Rivets are staggered to obtain max strength. Using 75% of existing Rivet pitch.

set the head of a screw or a rivet flush with the material in which it is being placed. Used on material.
