Bolt with Nord-Lock washer Rivets A high clamp load can be developed just by turning the nut and bolt. Because rivets have no threads, they can create an extremely limited clamp load. Corrugated Fasteners. Through hole setup requires access to both sides of the bolted joint. However, this can be fixed by a tapped hole design.

Useful in applications with minimal access to the opposite side. Standard handheld tools suffice. Specialized tooling required for installation. While standard threaded bolts will loosen up when subjected to heavy vibration, it can be avoided by securing with Nord-Lock washers (Round Head Fasteners). Will not rotate loose because of vibration. Can be eliminated quickly and quickly utilizing standard tools, and parts can be recycled.

Unable to be reused. Quick and basic. For example in the construction industry used with simple to set up HV/HR packages. Lengthy.

Together, they ensure uniform compression and hole fill. This, in turn, lets blind rivets join a variety of dissimilar materials, including metals, plastics, and woods. Designers select blind rivets based on the specific applications, and mandrels for how they carry out as a built-in tool. The style difficulty is to combine the right rivet size and configuration (tapered, float, sharp edged, or serrated) to the ideal mandrel for strong joints and rivet integrity.

Blind rivets can make up for irregular holes, as long as they are within 0. 004 in. of the rivets' expansion variety.
