Why Structural Breakstem Fasteners?
Avdel Cherry structural breakstem rivets have been designed to fulfill a variety of functions across a wide range of assembly applications. Labor-intensive operations which require access to both sides are made obsolete with Avdel Cherry's structural breakstem rivet range. The advantages offered by these unique fastening methods are:
Installation: The installation of Avdel Cherry structural blind rivets is easily accomplished with the use of hydra-pneumatic tools. Avdel Cherry manufactures tools from basic handheld tooling to elaborate multihead and/or bowl-fed equipment.
Selecting the Proper Fastener
NOTE: Good design practice dictates that a fastener should not be used in material thicknesses which fall outside of the specified grip range or recommended hole size. Material Combinations:Avdel Cherry Textron offers a variety of material and head style combinations to best suit customer requirements.

Head Styles
|
||||||||||||||||||||||||||||
| Protruding (P) This is the most common head style used. The head forms a footprint above the outermost sheet being fastened for an impeccable "finished" appearance. | ||||||||||||||||||||||||||||
| Brazier (B) This protruding style is specifically designed to impersonate the profile of a solid rivet | ||||||||||||||||||||||||||||
| Large Flange (L) Designed to achieve a larger footprint on the outside material) than the protruding head style. Excellent for fastening a soft or brittle material to a solid backing. | ||||||||||||||||||||||||||||
| Countersunk (C) Designed to provide a flush surface finish. Available in 120° or 100° styles | ||||||||||||||||||||||||||||
