DIN 965 screw black steel flat head screw phillips metric machine screws
DIN 965 screw is the screw with Philips or pozidriv screw drive and flat (countersunk) head and machine threaded. The screws are commonly used in machine parts, die fixturing, and clamping. The flat socket head enables driving where there is not sufficient space for wrenches or sockets and allows the screw head to sit flush on the surface. Ever Hardware provides DIN 965 screw with shoulder and customizable packaging.
The Phillips screw drive was created by John P. Thompson, who after failing to interest manufacturers, sold his design to businessman Henry F. Phillips. Phillips is credited with forming a company (Phillips Screw Company), improving the design, and promoting the adoption of his product. The original patent expired in 1966, but the Phillips Screw Company continued to develop improved designs.
Phillips drive bits are often designated by the letters “PH”, plus a size code 0000, 000, 00, 0, 1, 2, 3, or 4 (by order of increasing size); the numerical bit size codes do not necessarily correspond to nominal screw size numbers.
Galvanization, or galvanisation, (or galvanizing as it is most commonly called in that industry), is the process of applying a protective zinc coating to steel or iron, to prevent DIN 965 screw rusting. The most common method is hot-dip galvanizing, in which parts are submerged in a bath of molten zinc. Galvanizing protects in three ways:
It forms a coating of zinc which, when intact, prevents corrosive substances from reaching the underlying steel or iron.
The zinc serves as a sacrificial anode so that even if the coating is scratched, the exposed steel will still be protected by the remaining zinc.
The zinc protects its base metal by corroding before iron. For better results, application of chromates over zinc is also seen as an industrial trend.
