CRL Blind Rivets in Cases are standard pack quantities as supplied from the factory.


A blind rivet is a simple device for holding materials together. A solid metal mandrel is inserted into a tubular metal rivet, and supplied as an assembled unit. This becomes a fastener when the mandrel and rivet are inserted into aligned holes in the materials to be joined. The mandrel is pulled into the rivet by a rivet setting tool CRL Marson® HD Gun (commonly known as a rivet gun) to create a counterhead, then the mandrel is snapped off, leaving the finished fastener. This effective fastening system lends itself to virtually hundreds of applications, joining materials of many thicknesses and varieties.

Blind Rivets were originally thought of as a specialty fastener for use in blind applications only, but they have proven their versatility in both high production assembly, and low volume piece work situations. Few fastening systems offer the flexibility of design, uniformity of results that Blind Rivets do. Blind Rivets feature: Low head profile and minimum back-up space; join thin gauge or dissimilar materials; vibration-proof - won't back out or shake loose; positive fastening of painted or finished components without possibility of surface marring; conform to industrial fasteners institute and appropriate government standards and specifications. Add to these advantages their ease of use, and you may begin to realize how using Blind Rivets could benefit your profit picture.

To find the proper catalog number, check the grip range and diameter below. When selecting the proper blind rivet to meet your requirements, take into account the joint strength, joint thickness, and nature of materials to be joined. Also consider the type of head that best suits the intended rivet application. The diameter of rivet you select will depend on the desired joint strength. Blind Rivets develop joint strength in two ways: by clinch of the counterhead and by compression of the rivet body against the walls of the hole. Rivet grip is the combined thickness of the materials being fastened. Select the rivet length by choosing one whose grip range includes the thickness of the materials to be joined. One length of rivet can be used for a range of material thicknesses. It is better to choose a rivet that is too long than one that is too short. You should consider also the materials to be joined. If using a soft material, you may need to use a rivet spacer , thereby increasing the requirement for the grip range slightly.
