Allen Wrench Screws Male Female Metric Hex Threaded Allen Bolt

Allen wrench screws have a hexagonal recess and may be driven by a hex wrench. Male and female screws are a combination of two parts, one male part is also called a screw and one female part is one kind of nut. The screws are used for connecting with the male part locking into the female part. Ever Hardware provides custom-made fasteners and customizable packaging.

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”.

Zinc-Nickel plating is one of the best corrosion-resistant finishes available offering over 5 times the protection of conventional zinc plating and up to 1,500 hours of Neutral Salt Spray test performance. This plating is a combination of a High Nickel Zinc-Nickel alloy (10% – 15% nickel) and some variation of chromate. The most common mixed chromates include Hexavalent Iridescent, Trivalent or Black Trivalent Chromate. Used to protect steel, cast iron, brass, copper, and other materials, this acidic plating is an environmentally safe option. Hexavalent Chromate has been classified as a human carcinogen by the EPA and OSHA.
