Roller Assembly
(Semi-Tubular & Tubular Rivet )

The following Roller Assembly uses semi-tubular rivets in multiple locations. These popular rivets are used to permanently fasten two or more pieces.  They are strong, inexpensive and well-suited for high-speed assembly operations with automatic feed riveting machines.

Roller Assembly

	Rivets R1 secure rollers to pivot frame
	Rivet R2 serves as pivot point
	Semi-tubular feature of R2 prevents compression of exterior plates & eliminates need for spacer

Door Hinge and Pulley (Solid Rivet )

The Door Hinge and Pulley applications below both use solid rivets for strength and durability.

Door Hinge

	Solid rivet functions as center pin of hinge assembly
	Attractive yellow zinc finish

Pulley

	Solid rivets are used to assemble a pulley from two stampings
	More economical than cast pulley, more durable than spot welds
	Excellent for high volume pulley production

Shutter Roller (Shoulder Rivet )

The shoulder in the roller application below acts as a bearing surface for the nylon rollers. Shoulder rivets offer a lower unit cost than similar screw machine parts, and can be assembled with automatic feed riveting machines.

Roller for Accordian Shutters

	Nylon rollers secured with shoulder rivets
	Rivet acts as bearing surface

Ball Bearing Rollers (Collar Rivet )

Collar rivets are a variation of the Shoulder Rivet. They can be used as a standoff - to separate components; or as a guide peg for mating assemblies; or as an anchor stud for a pivoting assembly. In the Roller application below, a collar rivet is fastened to the ID of a ball bearing.

Collar rivet fastens ball bearing at a specific distance from frame

Vapor Plug (Cross Drilled Rivet )

The key to operation of this Vapor Plug is a Cross Drilled Rivet. These rivets often function as a hinge pin and are generally secured with a cotter pin or a hitch clip. In this application however, the cross drilled rivet is permanently attached to the lever with a semi-tubular rivet.

(Removable) Vapor Plug

	Cross drilled rivet functions as a clevis pin
	Plates A and B are pushed together when Lever is closed
	Not shown - Annular ring (elastomeric) is compressed between plates, thereby expanding to provide vapor seal.
