of Atlas® Plus+Tite® blind threaded steel inserts has
expanded with a newly introduced version featuring a straight shank design. This
fastener joins Plus+Tite pre-bulbed inserts in offering pullout resistance when
installed permanently in plastics or thin sheet metal. Both types provide reusable
threads for "blind" attachment applications, including tubing and extrusions,
where only one side is accessible for fastener installation and component
assembly. A single mating screw completes the final attachment process.
inserts can install permanently into single, variable or multiple-thickness materials
as thin as .020 inch / 0.50 mm. The straight shank design will accommodate a
smaller mounting hole and the pre-bulbed inserts will require less installation
Both install from
the accessible "front" side of a component. Installation can be accomplished
anywhere and at any stage in the shop or field using either a spin-pull tool or
spin-spin tool, depending on insert type. A shoulder on both styles serves as a
The inserts are
available with internal formed threads in sizes #10-32 through 3/8-16 and M6
through M10. Threads are compatible with unified grade 5 or metric class 9.8
screws. All insert surfaces are plated for corrosion-resistance.
Two different shape-shifting polymers have been announced from two different universities: Wyss Institute at Harvard University and Zhejiang University in eastern China. Both of them change their shapes when immersed in water, and the one from Wyss Institute was made with 3D-printing techniques.
When you think of the DARPA Robotics Challenge, you may imagine complex humanoid contraptions made of metal and wires that move like a Terminator Series T-90. But what actually happened at the much-vaunted event was something just a bit different.
