Mechanical Fasteners

Here are several basic points engineers should consider to help zero in on the hinge best suited for a particular enclosure

Fredserts give engineers a new way to put bolts in soft metal

An approach to strength calculations for bolts subjected to periodically changing loads.

Bolt tensioners securely fasten large-diameter bolts

The equations that govern bolt loads can help engineers correctly size bolts for joints

The clamp works on process-equipment access panels of aluminum, steel, and other materials.

The pins come in a variety of diameters, finishes, and detent designs.

The tab washers come in multiple configurations and materials.

The washers and spacers come in a variety of materials, ODs, IDs, and thicknesses.

The plungers allow quick, tool-free repositioning of panels on slides and tracks.

Aluminum-body gear reducer

A speed reducer built by the Italian firm Varvel is now available through DieQua Corp., Bloomingdale, Ill. It features a square aluminum body and uses worm wheels

A simpler way to predict bolt preload

Generalized torque coefficients and a universal torque table give engineers an easier path to accurate bolt preloading

The studs install into single or multiple sheets.

Clamp nut from Hytorc provides secure fastening for critical applications

The press automatically installs self-clinching fasteners in sheet metal using electro-mechanical servos.
