Ask Hackaday: Is There a Common Mechanical Parts Library? | Flat Torx Self Drilling Screw

Pakistan’s ad industry has mostly been driven by legacy (and legendary) entrepreneurs. Prince Abbas Mirza (D.J. Keymer and of pre-partition heritage), Anwar Rammal, Shaukat Fancy, Naseer Haider, Javed Jabbar, the Thavers, S.H. Hashmi, C.A. Rauf, Bashir Khan and countless others. Later, Taher A. Khan, Shahnoor Ahmed, Jawaid Iqbal and Imran Mir built great advertising businesses.

Since cricket – the most glamorous of sports – had become the exclusive property of Wills, other brands had to settle for ‘lesser’ sports. Lakson Tobacco’s Royals Filter began to sponsor football, which perhaps gave a boost to the game. Other lower-priced ones had to opt for sports such as wrestling and kabbadi.

Of these, English Cold Storage was a favourite; it was there that cold cuts, Swiss liqueur chocolates, cereals, and cheeses, be they of the Danish or Dutch variety, could be sourced. Incidentally, the first cheese to be made in Pakistan was called Amson’s; it was made by Amson’s Dairy and instead of being available at a retail store, one had to go to the owner’s flat located in an impressive stone building, on the corner of Inverarity (now Sarwar Shaheed Road) and Victoria Roads (now Abdullah Haroon Road) to purchase it, where it was packed in paper like butter, which Amson’s also sold.

In this respect, Lahore owes a lot to the outdoor industry, given that the city’s horticulture landscape was mainly funded by taxes collected from the outdoor media. So aggressively did the authorities collect funds in exchange for permission to erect billboards that an unprecedented number of structures went up between 2000 and 2010, especially in Lahore. Inevitably, clutter began to compromise the effectiveness of the medium and in 2008, the Punjab Government took measures to rationalise the installation of outdoor structures.

- Allen wrenches tend to be steel bars bent into an L-shape and are specially designed for hex-head screws and bolts. You’ll often get these ‘for free’ with self-assembly furniture.

An expanded line of deep hole drilling and machining centers will complement the existing USC-M series, 4- to 7-axis deep-hole drilling and machining centers.

MiTek® Launches Its New ProSeries™ Fasteners, Offering Exterior-Grade & Interior-Grade Structural Wood Screws

If you are going to be hitting something, breaking something or assembling things with nails you’ll need a good ol’ hammer.

One reason threaded fasteners are so widely used is that they can generate a tremendous amount of clamp load in a small area. Clamp load is central because it is the mechanism by which joint components are held together without moving relative to one another—arguably the primary requirement of a structural joint. However, placing a large load on a small area creates a high level of stress, which, in turn, can lead to problems. For example, a ½ – 20 Grade 8 bolt can supply nearly 20,000 pounds of clamp load. A standard hex head bearing on a standard 9/16-inch clearance hole means all that load would act on an area only half the size of a dime. The resulting stress exceeds the yield strength of most materials. An analogy is the effect spike heels can have on wood floors.

“We’ve been working on some new micro screw [toy applications] that are down in the M1 range, [similar to what’s] found in cell phones and tablets, but they are not the norm yet,” says Mowins.

“The cost advantages in China are substantially less than they were a few years ago, so companies are going to be re-evaluating whether it makes sense to import toys vs. producing domestically,” adds Daniel Berch, director of Pell Research LLC. “Particularly, higher-end [production] processes and automation make U.S. manufacturing more feasible.”

Naturally, it was only a matter of time before the artists behind the music drifted into the spotlight, cementing their celebrity status by pairing up with successful brands. In the early nineties, Vital Signs were catapulted into stardom after appearing in a series of Pepsi commercials.
