The noncircular thread-forming zone enables simple, concentric insertion, resulting in easy fastening of the screw with less installation torque. Raised thread areas facilitate safe and secure penetration into the sheet material.
Depending on your needs a good jack will go a long way. They are great for anyone who likes to tinker with their car but has many other applications.
During an interview with Dawn, Nasir stated that: “From the mid-fifties to the mid-sixties, Radio Pakistan was at the zenith of its success, not only because there was no competitive medium or source of information, education and entertainment, but because it was run in such a perfect manner; it was at par with many international radio services.”

Anytime a clamp-on TPMS sensor is reused or replaced on a wheel, it is necessary to install new seals and valve stem nuts to ensure proper sealing around the sensor valve stem.
The right drill for you will depend on the task at hand so you should do some research before buying one.
Profile 9701 is also 1.5 inches square, but features predrilled holes at 1.5-inch intervals along each face. These holes accept fasteners and allow for applications such as conveyor tables, gravity racks and material-handling shelves. Nearly a dozen other profiles feature one or two flanges on each side, with or without predrilled holes, for extra weight capacity.
For the most part, advertising agencies had to resort to an approach that boiled down to saying: ‘Please buy the product.’ Although a few advertising professionals did find ways to overcome this obstacle, many creative people became increasingly frustrated as they had no choice but stifle their creativity.
However, they usually offer less insulation than the materials they mimic (upping your heating or cooling costs). And, while they’re suitable for installation in all climates, low-quality composite shingles—which can be prone to absorbing water—may soak, freeze, and warp more quickly in locations that frequently experience rain or regular cycles of freezing and thawing. One more point to consider before committing: A relative scarcity of roofers experienced with this fairly new type of shingle can also make it trickier to achieve a quality installation. (Lucky for DIY-inclined homeowners, the replacement of individual damaged shingles doesn’t require a pro the same way that repair on heavy genuine slate shingles would.)
The torque-absorbing nibs are positioned at the outer perimeter of the screw head. They are higher on the advancing edge for better torque absorption. (A reverse taper is available with a high edge on the back side to resist reverse rotation and lock the fastener in place.) In addition to absorbing torque, the Ger-Nib scrapes through paint or plating to provide a secondary ground. Screws with this unique feature can accommodate a wide range of metal thicknesses.
