Manufacturers in many industries select these screws because they prevent cross-threading, resist vibration and are reusable. Another appeal is versatility. The screws can be used in aluminum, magnesium and plastic, as well as sheet metal, and some suppliers offer thread-rolling bolts.

NYE was a particularly busy time, with not just the big hotels hosting events but everybody and his brother vying to ‘ring in the new year’, with a party of his own. A few of the embassies (Karachi was then the capital), all the private clubs, and some wealthy individuals also did their bit to add to the festivity.

For less than five rupees (considered pricey in those days), one could dig into a plate of egg fried rice and sweet and sour chicken, as well as noodles and fried prawns in a crisp batter. Another popular Chinese restaurant was the South China Cafe near Paradise Cinema. Here, the flavours were more Cantonese. There was also Canton adjacent to Happy Book Stall on Inverarity Road and Hong Kong on Victoria Road. Soon, Chinese restaurants opened in Tariq Road and included Tung Nan and Yuan Tung, which was initially located near Bunder Road (now M.A. Jinnah Road).

EVOTEC is available in one size (7.87” x 4.88”) and in one standard color: off white (RAL 9002). Prices start at $25.

You could call the Klein Tools Screwdriver and Nut Driver 11-in-1 Multi Tool cheap, but that would only be true in terms of cost. While it costs less than fifteen bucks, it’s actually a surprisingly well-made tool that’s more than capable of handling a range of light duty tasks.

Governments can help by putting in place policies, incentives and regulations to prevent abandonment and facilitate removal. Domicology will depend on figuring out the best processes and technologies for safe removal. Deconstructors will need to hire differently skilled laborers than for a standard demolition. And for domicology to work there will need to be a way to take the removed material to a place where it can be given a second life of some kind.

Joe Beard, prototype/engineering manager at IMD says, “Bal Seal Engineering worked with us to develop the correct spring and groove setup we needed. In the end, it yielded great results, and the collaboration allowed us to improve functionality while being proactive about cleanability.”

“Because these screws often require equal or greater torque for the thread rolling, forming or cutting operation than the final fastening torque, ensuring a secure joint can be difficult,” acknowledges Kevin Buckner, director of engineering at Design Tool Inc., which makes equipment that automatically feeds and drives all types of fasteners. “To overcome this problem, we often use DC screwdrivers equipped with transducers for these types of screws. DC drivers allow multiple tightening steps during screwdriving that verify thread cutting has been completed and that the final required torque value is within tolerance.”

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

Once we have a project-customized connector designed and printed, we proceed to assembly where we face the other hidden gotcha of aluminum extrusions: specialty fasteners. Called T-slot inserts, T-nuts, or some similar name, they are shaped specifically to fit in the slot of an aluminum extrusion beam. They are also extremely expensive. Not necessarily in an absolute sense, but certainly relative to commodity hex nuts of similar size. Our rocker arm example is designed for 15mm Misumi 3 Series extrusions. Misumi offers several specialty nuts for this extrusion, the least expensive “economy” model HNSQ3 costs $8.28 for a bag of 100. In contrast, our trusty hardware supplier McMaster-Carr offers generic M3 hex nuts at $0.88 for a bag of 100. (Catalog #90592A085)

Vises are an essential piece of kit for many tasks like cutting length of pipe, bending or shaping things or generally holding something tight in place. They come in either stationary or swiveling varieties but for heavy-duty work, you really want a forged-steel one.
