M2.5-0.45 Socket Head Insert Screw Replaces Carbide CNC Accessories Lathe Tool Torx Black Oxide Grade 12.9

Description

M2.5-0.45 Socket head insert screw is the screw for mill inserts. The screws are usually made of SCM435 with heat treatment to Grade 12.9 and black oxide. Ever Hardware provides custom-made fasteners and customizable packaging.

• Suitable for carbide inserts CNC Lathe Tool, CNC machine.
• High-quality alloy steel material in silver tone, designed with Torx type flat head.
• Chamfered ends for easy insertion.
• High tensile for more durable.

Torx is a popular generic name for the drive is a star, as in star screwdriver or star bits. The official generic name, standardized by the International Organization for Standardization as ISO 10664, is hexalobular internal. This is sometimes abbreviated in databases and catalogs as 6lobe (starting with numeral “6”, not a capital “G”). Torx Plus is an improved head profile. Torx screws are commonly found on automobiles, motorcycles, bicycle brake systems (disc brakes), hard disk drives, computer systems, and consumer electronics.

Black oxide or blackening is a conversion coating for ferrous materials, stainless steel, copper and copper-based alloys, zinc, powdered metals, and silver solder. It is used to add mild corrosion resistance, for appearance and to minimize light reflection. To achieve maximum corrosion resistance the black oxide must be impregnated with oil or wax. One of its advantages over other coatings is its minimal buildup.

12.9-grade M2.5-0.45 socket head insert screw 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 6.8, 8.8, 10.9 also. This is an imperial method implied by engineers to differentiate between different sets of steel grades. Mainly used to differentiate the bolts and nuts. like Grade 12.9 Hexagonal Bolt.
