Value Collection 534024P M4x0.7 Flat Socket Cap Screw

Product Description

The VALUE COLLECTION 534024P is a metric flat socket cap screw designed for flush or countersunk fastening applications in machine assembly, tooling, and precision fabrication work. It features a 90-degree flat head with a hex socket drive and is manufactured from 12.9 grade alloy steel with a black oxide finish. The 12.9 material grade indicates high tensile strength, making this screw suitable for demanding clamping and structural fastening tasks. It is fully threaded along its 10 mm overall length with an M4x0.7 thread and conforms to DIN 7991. Machinists, maintenance technicians, and industrial assemblers are the primary installers.

This screw is used in applications where a low-profile or flush-mount fastener is required. The 90-degree flat head seats into a countersunk hole, keeping the mating surface clear of protrusions. Common install scenarios include machine tool fixtures, jigs, guards, and precision mechanical assemblies where head clearance is critical. The black oxide finish provides mild corrosion resistance in dry or lightly oiled environments and reduces surface reflectivity, which is useful in optical or inspection environments.

Key Features

• M4x0.7 metric thread, fully threaded along the entire 10 mm overall length
• 90-degree flat head profile seats flush in countersunk holes per DIN 7991
• 2.5 mm hex socket drive for precision torque application with standard Allen keys
• 12.9 alloy steel construction for high tensile and proof load strength
• Black oxide finish for mild corrosion resistance and low-reflectivity surface
• Conforms to DIN 7991 fastener standard

Compatibility

Designed as a DIN 7991-compliant metric flat socket cap screw for M4x0.7 countersunk applications in machine assembly, tooling, and precision fabrication where a flush-mount fastener is required.

Installation Notes

Installation requires a 2.5 mm hex key or Allen driver. Countersink the mating part to the correct 90-degree angle before installing to ensure proper head seating and clamping force. Power down or de-energize any equipment before servicing fasteners on live assemblies. Do not exceed the torque rating specified in the applicable engineering or equipment documentation for 12.9 grade M4 fasteners.
