Value Collection 43145 M6x1 Flat Socket Cap Screw 12.9 Steel

Product Description

The VALUE COLLECTION 43145 is a metric flat socket cap screw designed for applications requiring a low-profile, flush-mounted fastener with high tensile strength. Built to DIN 7991 standards, it features a 90-degree flat head driven by a 4 mm hex socket. The screw is manufactured from 12.9 grade alloy steel with a black oxide finish that provides moderate corrosion resistance and a consistent dark appearance. Sized at M6x1 with a 12 mm overall length and fully threaded shank, this fastener is suited for precision assemblies, machine components, and structural connections where a countersunk profile is required.

This fastener is used in metric-standard assemblies across industrial, mechanical, and manufacturing environments. The fully threaded M6x1 shank allows engagement along the full length of the fastener, making it appropriate for thin-stock applications or through-bolt configurations. The 12.9 material grade indicates high-strength alloy steel capable of handling elevated clamping loads. These screws are typically installed by machinists, millwrights, maintenance technicians, and mechanical assemblers working with metric hardware.

Key Features

• DIN 7991 fastener standard ensures dimensional consistency across metric assemblies
• 12.9 alloy steel grade provides high tensile and proof load capacity
• 90-degree flat head profile allows flush or countersunk seating
• 4 mm hex socket drive accepts standard metric hex keys and bits
• Fully threaded shank for maximum thread engagement across the full 12 mm length
• Black oxide finish reduces light reflection and provides mild corrosion resistance

Compatibility

Designed as an OEM-style replacement or direct-install metric fastener for machinery, equipment panels, and assemblies specifying DIN 7991 M6x1 flat socket cap screws.

Installation Notes

Installation is performed using a 4 mm hex key or hex bit driver. Ensure the mating hole is properly countersunk to 90 degrees before installation to allow full head seating. Torque to the specification listed in the equipment service documentation for 12.9 grade M6 fasteners. Do not reuse fasteners that show signs of thread damage, galling, or deformation.
