Value Collection 43148 M6x1 Flat Socket Cap Screw 12.9 Alloy Steel

Product Description

The VALUE COLLECTION 43148 is a metric flat socket cap screw designed for applications requiring a low-profile, flush-mount fastener. Built to DIN 7991 standard, this screw features a 90-degree flat head with a 4 mm hex socket drive and is fully threaded along its 25 mm overall length. Manufactured from 12.9 grade alloy steel with a black oxide finish, it delivers high tensile strength and moderate corrosion resistance. This fastener is a standard choice for machine assembly, tooling fixtures, and mechanical subassemblies where the head must sit flush or below the surface of the mating material.

This screw is suited for precision mechanical and industrial assembly work across a wide range of applications. The M6x1 thread size and 25 mm overall length make it a common fit for machine tool components, jigs, brackets, and structural assemblies where a hex socket drive allows access in tight clearance zones. Installers working in manufacturing, maintenance, and fabrication environments will find this screw compatible with standard metric hex key tooling.

Key Features

• DIN 7991 fastener standard ensures dimensional consistency and interchangeability
• 12.9 grade alloy steel provides high tensile and proof load strength
• Black oxide finish offers mild corrosion resistance and a low-reflectance appearance
• 90-degree flat head profile allows flush or countersunk installation
• 4 mm hex socket drive accommodates standard metric Allen keys and socket drivers
• Fully threaded along the 25 mm length for maximum thread engagement

Compatibility

Designed as a DIN 7991 metric flat socket cap screw for use in countersunk applications requiring an M6x1 thread pitch and 25 mm overall length.

Installation Notes

Installation requires a 4 mm hex key or socket driver. Ensure the mating material is drilled and countersunk to the correct 90-degree angle before driving the screw to avoid head deformation. De-energize or lock out any equipment before performing fastener service on machinery. Follow applicable machine guarding and torque standards from the equipment manufacturer or relevant industry codes.
