How to Use a Circular Saw: Training the Apprentice | Metric Wood Screws

Other times, standards exist not for international cooperation or scientific accuracy, but because it’s really, really important for things to work. Craig Murphy is a political scientist and the co-author of The International Organization for Standardization (ISO): Global Governance Through Voluntary Consensus, with JoAnne Yates. He gives the example of condoms, which require fastidious and complex standardization. “There are multiple condom standards, because there are multiple sized people, and condoms are used slightly differently in different parts of the world,” Murphy says. Since 1975, somewhere in a room near Geneva airport, teams of engineers have sat around in technical committees, talking about condoms—“smooth, textured, parallel-sided, non-parallel-sided, plain-ended, reservoir-ended, dry, lubricated, transparent, translucent, opaque, colored, pre-shaped, welded or non-welded,” according to the standard.

The factors contributing to this development are changing consumer behaviour patterns (not least the fact that they are spending more time out of home). There was a time, when during the airing of popular TV dramas, the roads would be relatively empty with people glued to their TV sets. Today, there is no TV show that audiences need to stay at home to watch live; they can watch it on their smartphones or watch the repeat the following day.

you can see the idea of what i mean. in the milling tool all of the teeth are of equal depth and you set your helical tool path based on your thread pitch desired. I have seen turning tools with even length teeth but they were in a specialty tool catalog for softer materials.

Thread-rolling screws were introduced in the 1960s as a non-chip alternative to thread-cutting screws for sheet-metal applications, according to Simpson. They have a tapered lead and require that the fastener be harder than the mating material. During installation, the fastener roll forms the mating material into the thread shape.

(3) Airbox. We don’t think changing an air filter could get any simpler. Plus, with a few strips of tape, you can turn it into a tuning tool.

Brand teams are forcing agencies to think short-term. Because of the financial crunch, agencies hire to fill their ranks with people with short-term objectives rather than a long-term vision. Ask yourself what is the key differentiation between your agency and any other in Pakistan?

The width or diameter of the nut also plays a part in its load capacity. Figure 6 shows the nut threads expanding away from the screw as mating threads slide relative to one another radially. This reduction in thread engagement, and therefore load capacity, is a function of the nut member’s stiffness in the radial direction. Width across the flats of standard nuts is about 1.5 to 1.6 times the nominal thread diameter. This is actually a compromise between strength and size, as a ratio of nearly 2-to-1 is required to eliminate dilation. Nuts are available in larger widths and lengths when required.

Somewhere along the line, activation practitioners in Pakistan have lost their way. After the gloss of this ‘new and exciting’ marketing medium wore off, brands realised that they had to justify their spend on activation compared to their spend on ATL. This realisation brought into question the infamous ‘cost per contact’ metric that drives the activation landscape today.

“Fortunately, advanced modeling software, as well as high-speed CNC machining centers, are embraced by the toy industry,” adds Holt. “So, these shapes can be accurately reproduced in the ultrasonic tooling even before molded parts [are] available.”

I’ve heard that some people like ratcheting screw drivers. I think these people have problems, but when they do work, they do work.

… Who can you trust? Some random guy out there, or some Anonymous Coward.I’m utterly perplexed and I don’t know who to believe anymore as both sides have such strong arguments. [youtube.com]
