MATERIALS: Acme Industrial Co., a subsidiary of Jergens Inc., has announced a new line of Key Locking Studs. These key locked fasteners (also known as staked studs), have a solid one-piece design to provide high pull-out strength and torque-out capabilities. They are used in original equipment, or to repair damaged threads. The studs’ keys are driven down into the threads of the surrounding base material to securely lock them into place and to provide a mechanical lock against vibration.
Acme Key Locking Studs are produced to NAS and SAE Standards (MS51833 and MS51834). They are available in a full range of inch and metric sizes, in both lightweight and heavy duty versions. The studs are available in a variety of materials, including 303, A286, 17-4PH CRES and 4140 Alloy Steel.
Key locked studs provide security and “repairability” in applications where a through-bolt / nut combination is not possible. They are superior for use in soft materials such as aluminum or magnesium. Installation is easy, using standard drills and taps. An important feature is the ability of staked studs to be removed without damage to the parent material by using a standard screw extractor.

The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
Some humanoid walking robots are also good at running, balancing, and coordinated movements in group settings. Several of our sports robots have won regional or worldwide acclaim in the RoboCup soccer World Cup, or FIRST Robotics competitions. Others include the world's first hockey-playing robot and a trash-talking Scrabble player.
