BDE-Fastening & Joining

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.

Soldering uses alloys that melt below 840°F to join metals.

Nonthreaded fasteners often are simple designs, but they solve a wide range of fastening problems.

Welding allows parts to coalesce along their contacting surfaces by applying heat, pressure, or both, and often adding a filler material.

Many applications require joining metals to ceramics, such as sealing electrodes to glass enclosures for light bulbs.

A clinch nut is a solid nut with a knurled or smooth shank or pilot projecting from one end.

Used primarily as safety nuts, these nuts are slotted to receive a cotter pin or wire which passes through a drilled hole in the bolt and locks it.
