“You can’t drive these screws in spots where you have close vertical restrictions,” says Baeumler.

Agencies responded by designing marketing activities, optimised to deliver the biggest bang for their buck in terms of cost per contacts. In all this hoopla, we collectively managed to critically wound, if not kill, the ‘experience’ part of experiential marketing.

Be they advertising professionals or members of the general public, many people are of the opinion that the sixties and seventies were the ‘golden age’ of Pakistani advertising. It was then that some of the best commercials were produced (some remembered to this day).

Movies and TV shows consistently promote lead characters who are able to complete their mission with little or no help from others. In the world of fastening, self-tapping screws fit this role better than any fastener, as they have the ability to create mating threads in metallic and nonmetallic base materials. By eliminating the tapping process, these fasteners (thread-cutting, thread-rolling and thread-forming screws) help manufacturers save money and increase production.

In short, they are an engineer’s best friend and ideal for making that just slightly over-sized rivet fit. They come in a variety of forms and you’ll want a nice selection depending on the task.

If you find yourself using CNC mills, 3D printers, CNC routers or laser cutters, calipers are a must for ensuring your material dimensions in software are consistent with the material’s actual dimensions.

In mid-19th-century United States, this became especially clear as railroads began to stripe across the country for the first time. Each place used its own measure to determine the space between the rails on the track. Some track gauge measurements were narrow—in parts of Maine, just two feet wide. Other places, like New York State, favored a gauge of up to six feet. If everybody remained in their “area,” this didn’t represent an especial problem. But increasingly, people, and goods, needed to be moved great distances, from one place to the next. Usually, railways resorted to a break of gauge, where everything and everyone would trundle off one train operating on one gauge, and onto the next train which operated on a different gauge. But this was an expensive, time-consuming solution and, as trade between the Midwest and the East mushroomed after the Civil War, it became a nuisance for trading companies.

The team at ARP prides themselves on maintaining tight tolerances and repeatable measurements on all their products. Make sure to inspect every single fastener prior to installing it into your engine. If you see an inconsistent thread, or a chamfer that doesn’t match all the others, make certain to replace those parts. The smallest variance can make a big difference in clamping performance. You wouldn’t accept it in your piston rings or roller lifters, so don’t accept flaws in your critical hardware either.

A group of men independently travelled to Karachi from near and from far… from Bhopal, Bombay, Delhi, Calcutta, Lahore, Lucknow… and many other cities in India. Others were Karachi born and bred.

Craftsman handles stink. Oh, they have an OK grip, and the shafts don’t seem to tear out, but search the term Craftsman with “cellulose acetate butyrate” and you’ll see what you’re in for. My Craftsman set is so old that all of them are the red handles on clear–I have no idea when they started color coding them.

One simply cannot engineer without tools. These 25 are some of the most essential pieces of kit any self-respecting engineer needs to have to hand.

- Bottle or piston jacks are also hydraulically operated and differ from floor jacks by being cylindrical in form. Their advantage over others is their small footprint.
