Mounting insert screw special type socket drive grade 12.9 black plating
Mounting insert screw is a threaded insert, also known as a threaded bushing, is a fastener element that is inserted into an object to add a threaded hole.screws for mill inserts. Ever Hardware provides custom made mounting insert screw 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”.
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 mounting insert screw rusting. The most common method is hot-dip galvanizing, in which parts are submerged in a bath of molten zinc.
12.9 grade steel means that a component manufactured form this grade of steel has 12X100 N/mm^2 tensile strength and 9 is a multiplier means 90% of 1200 = 1080 N/mm^2 is the yield strength of the grade. Similarly we also have grade 8.8 , 10.9 , 6.8 also. This is imperial method implied by engineers to differentiate between different sets of steel grade. Mainly used to differentiate the bolts and nuts. like Grade 12.9 Hexagonal Bolt.
