Permanent threads in thin sheet applications -- with only one-sided access
ATLAS SpinTite blind threaded inserts from Penn-Engineering provide strong, permanent, and reusable threads in thin sheet materials where only one side is accessible for hardware installation. Installation is performed from the accessible "front" side using spin-spin tooling technology. The inserts then become permanently mounted on the "back" side to accept a mating screw for final component attachment. This "blind" installation capability especially suits applications such as tubing, extrusions, and others where access to the back side is either limited or nonexistent. These steel, aluminum, brass, or stainless steel inserts support close-to-edge applications and can be installed at any stage during the production process (even after assemblies have been painted).

Scientists predict a new superhard material with unique properties
Chemists from Russia and China have predicted a new superhard material that can be used in drilling, machine building, and other fields.
The new tungsten boride they discovered outperforms the widely used "pobedit," a hard tungsten carbide and cobalt composite material with artificial diamond interspersing. The results of their study were published June 2 in The Journal of Physical Chemistry Letters.
Superhard substances have a broad scope of application spanning well drilling, machine building, metalworking, defense industry, surgery, and many other fields. The hardest known material, diamond, is an unaffordable luxury in many applications. Its distant competitor, pobedit, has remained unrivaled for the last 80 years.
Developed in the 1930s, pobedit was used during World War II to make anti-tank shell caps (the word "pobedit" is actually derived from the Russian "pobeda," which means "victory") and has been used for decades to manufacture drill bits for drilling rigs. Harder materials either require higher pressure synthesis or have much lower fracture toughness.
A team of Skoltech (Moscow) scientists led by Professor Artem Oganov used their USPEX evolutionary algorithm to predict a new material, WB5, that can be synthesized at normal pressure and can successfully compete with pobedit in the two most essential parameters -- hardness and fracture toughness -- which are 50 percent higher and 20 percent lower, respectively, for WB5 as compared to pobedit. The new material is a previously unknown compound that can be easily obtained under normal conditions. The Skoltech scientists performed their study within the framework of Gazprom Neft's large-scale project aimed at creating new materials for drilling applications.

"Before we discovered the new material, we had studied a lot of systems on the computer, trying to predict stable chemical compounds and calculate their properties. These were quite interesting substances, although they could hardly compete with pobedit. At some point I thought we would never beat pobedit, which has stood its ground for almost a century -- and for good reason. But suddenly, we saw a glimmer of hope and soon found a unique compound, WB5," says the study lead, Artem Oganov.
"The tungsten-boron system has been the subject of a multitude of experimental and theoretical studies, and it is surprising that this compound has not been discovered until now," says the first author Dr. Alexander Kvashnin.
