BEST ANSWER: They are screws, not nails, which is the beauty of these hangers. I don't have them handy any longer to measure, but I also ordered the larger sawtooth hanger, and the screws to that one are 7/16 of an inch long in total and about 3/8 inch under the head of the screw to the tip.

Starch (carbohydrates) is the toughest thing to forage for, and is a primary reason why humans settled down 10,000 years ago to …
In 1990, 70% of the uranium produced was from in-situ leaching of ore deposits with very low grades of 0.02 - 0.07% of uranium [Kuzmanov1993]. In the years 1991 - 1992, 14,000 wells in 15 in-situ leaching fields were in operation [OECD1994]. The total area used for in- situ leaching comprised 6 km 2 [Vapirev1996]. The total production from in ...
Hatchery crews in Stanley must fight through sub-freezing temperatures to produce Chinook salmon for Idaho anglers. Running water is the lifeblood of the hatchery, according to the Idaho Department of Fish and Game. But, winter temperatures can be sub-freezing for days, if not weeks, and sub-zero temperatures are common. Aside from the Arctic temperatures, snow removal on the hatchery …

The first sample collected is taken on Day 3 – after the faucet has been rinsed to remove debris and flushed ten times with the water allowed to stagnate 8 times for 2 hours and twice overnight. Because the amount of leaching is expected to drop with each flush, the …
Thallium- Drinking Water Contaminants, Facts/Removal Methods. Man-made sources of thallium pollution are gaseous emission of cement factories, coal-burning power plants, and metal sewers. The leaching of thallium from ore processing operations is the major source of elevated thallium concentrations in water. Thallium is a trace metal associated with copper, gold, zinc, and cadmium. …
Using the chemicals will also remove any wax or finishing polishes from the paint surface. Replace the finish as soon as practicable both for appearance's sake and to protect the paint from UV rays and atmospheric leaching. Removing tar is an entirely different project: Tar is petroleum-based, and the chemicals used to break down its structure must necessarily be far more aggressive. Follow ...
Dust samples were collected by MSHA inspectors from several mines in each of MSHA's 10 bituminous Coal Mine Safety and Health Districts. Samples were normally collected in several intakes at each mine. The laboratory analysis procedures included acid leaching of the sample to remove the limestone rock dust, sonic sieving to determine the dust size, and low-temperature ashing of the sieved ...
Tomas Havlik et al.: Pressure Leaching of EAF Dust with Sulphuric Acid 1 Introduction During the production of steel from scrap in electric arc furnaces a considerable degree of dust is recovered in gas cleaning units. In recent years the presence of leachable Zn, Pb, Cd, Cr and other metals within the dust has caused the material to be widely regarded as a toxic waste that is unsuitable for ...

Remove remaining moss with a scrub brush, and rinse the roof again. Alternatively, you can use a power washer to clean away moss, but there are several caveats to consider. First, you need to ensure that roof shingles and tiles are not broken, chipped, or damaged, as water applied at a high-pressure is likely to amplify the damage and seep through any cracks. Also, when using a power washer ...
