Flat head cap screw socket cap flat head bolts machine bolt
Flat head cap screw is also known as socket cap screw or hex cap bolt. The hex socket screw drive has a hexagonal recess and may be driven by a hex wrench, also known as an Allen wrench, Allen key, hex key or inbus as well as by a hex screwdriver (also known as a hex driver) or bit. Tamper-resistant versions with a pin in the recess are available.
The German company Bauer & Schaurte patented the hex socket 1936 in Germany, and offered products based on it to the market. The abbreviation “Inbus” is derived from “Innensechskant Bauer & Schurte”, analogous to the US use of “Allen key”.
Ever Hardware provides custom made flat head cap screw and customizable packaging.
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 flat head cap 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.
