BDE-Fastening & Joining

Annular snap fits aren't well understood but can be a handy means of making assemblies easily disassembled or permanently joined together.

Fasteners come in a variety of materials.

Split rings formed and cut from spring wire of uniform cross-sectional size and shape are known as wire-formed rings.

Fasteners also prevent gases and liquids from leaking.

Retaining elements to hold wires or tubing are incorporated into these fasteners that engage panel holes, mounting flanges, or panel edges.

Some joint-design considerations are universal; others vary with the assembly methods used.

These fasteners should be used when repeated access to a component is necessary.

Plate or anchor nuts have one or more lugs projecting from the base of the threaded body.

Almost any robot can be used for assembly, but only some have capabilities suitable for high-precision or high-volume assembly.

Superalloys and exotic metals are used to make fasteners that withstand high temperatures.

Push-on, tubular, and self-threading stud receivers attach to unthreaded studs, rivets, pins or rods of metal, plastic, or wood.

When the chosen joining method involves the use of fasteners, the choice of fastener can be as important to joint integrity as the joint design itself.

There are several techniques for joining plastic parts.
