Value Collection 43129 Flat Socket Cap Screw M4x0.7 25 Pack

Product Description

The VALUE COLLECTION 43129 is a metric flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. Built to DIN 7991 standard, this screw features a 90-degree flat head driven by a 2.50 mm hex socket. The M4x0.7 thread is fully threaded along the entire 10 mm overall length. Manufactured from 12.9 grade alloy steel with a black oxide finish, this fastener delivers high tensile strength and moderate corrosion resistance. Licensed trades and maintenance technicians use this fastener where a low-profile, high-strength metric screw is required in confined or cosmetically sensitive assemblies.

This screw is suited for precision mechanical assemblies, machine frames, tooling fixtures, and equipment enclosures where a flush seating surface is needed. The metric thread and DIN 7991 specification make it a standard fit in European-designed equipment and machinery. The black oxide finish reduces light reflection and provides a degree of surface protection in dry or mildly humid indoor environments. Sold in a package quantity of 25 per order.

Key Features

• 90-degree flat head profile for flush or countersunk installations
• 2.50 mm hex socket drive for precise torque application in tight spaces
• 12.9 grade alloy steel construction for high tensile and proof load strength
• Fully threaded M4x0.7 shank along the full 10 mm length
• Black oxide finish for reduced reflectivity and mild surface protection
• Conforms to DIN 7991 fastener standard

Compatibility

Designed as an OEM-style replacement or service fastener for metric-spec mechanical assemblies requiring a DIN 7991 M4x0.7 flat socket cap screw with a 90-degree head angle.

Installation Notes

Installation requires a 2.50 mm hex key or socket driver. Ensure the mating countersink is machined to the correct 90-degree angle to achieve full head seating before applying final torque. De-energize and lock out any equipment before replacing fasteners on live assemblies. Follow applicable equipment manufacturer torque specifications for M4 class 12.9 hardware.
