Value Collection 534086PR M6x1 Flat Socket Cap Screw 12.9

Product Description

The VALUE COLLECTION 534086PR is a metric flat socket cap screw engineered for applications requiring a low-profile, flush-mount fastener. Built to DIN 7991 standard, it features a 90-degree flat head with a hex socket drive and is fully threaded along its 35 mm overall length. The fastener is manufactured from grade 12.9 alloy steel, which provides high tensile strength suitable for demanding mechanical and structural assemblies. A black oxide finish offers moderate corrosion resistance and reduces light reflection. Installation requires a 4 mm hex key. This screw is intended for use by machinists, maintenance technicians, and industrial assembly professionals.

This fastener is well suited for metric mechanical assemblies where a countersunk, flush-seating fastener is needed. The 90-degree flat head seats cleanly into standard countersunk holes, making it appropriate for machine frames, fixtures, tooling plates, and equipment panels. The M6x1 thread pitch and 35 mm overall length cover a wide range of medium-duty fastening tasks in both OEM production and field maintenance environments.

Key Features

• Grade 12.9 alloy steel construction provides high tensile and proof load strength
• 90-degree flat head with hex socket drive for flush countersunk installation
• Fully threaded M6x1 metric thread along the entire 35 mm length
• Black oxide finish for moderate corrosion resistance and low-glare appearance
• Conforms to DIN 7991 fastener standard
• 4 mm hex socket drive size for precise torque application

Compatibility

Designed as a standard DIN 7991 metric flat socket cap screw compatible with any countersunk M6x1 threaded hole requiring a 90-degree seating angle.

Installation Notes

Installation should be performed using a calibrated 4 mm hex key or hex bit driver to ensure proper seating and avoid drive damage. Countersunk mating holes should conform to DIN 7991 geometry to achieve full flush seating of the flat head. Grade 12.9 fasteners are susceptible to hydrogen embrittlement and should not be exposed to electrolytic plating processes after installation. Follow applicable machinery or structural assembly standards for torque requirements based on thread size and application.
