B position: B ideas are present in equipment thread screws and they are for metallic, plastic and plywood, where a pilot hole has been drilled. They are often most effective for shallow holes
they've got uniform threads, and so are solid with the next torque pressure. This implies you would like less socket screws to fasten two resources than when you used a distinct screw.

Black Japanned Screws: These screws are protected that has a black enamel which may be Employed in black fittings and may deliver corrosion resistance
Also, tamper-resistant screws aren’t almost as check here robust as normal Phillips drives. They can be difficult to use in higher-torque purposes and can't be designed to fulfill high power benchmarks.
these are typically the screws that happen to be commonly referred as being the flat head screws a result of the slender opening furnished for flat screw driver.
