Value Collection 534048PR M5x0.8 Flat Socket Cap Screw

Product Description

The VALUE COLLECTION 534048PR is a metric flat socket cap screw designed for applications requiring a low-profile, flush-mount fastening solution. Manufactured from 12.9 grade alloy steel with a black oxide finish, this screw delivers high tensile strength and moderate corrosion resistance. The 90-degree flat head seats flush with the mating surface, driven by a 3 mm hex socket. It carries an M5x0.8 thread and measures 8 mm in overall length, fully threaded. Licensed fastener technicians, millwrights, and precision equipment assemblers use this screw where protruding fastener heads are not acceptable.

This flat socket cap screw is suited for machine assembly, fixture fabrication, and precision equipment construction where a countersunk, flush-mounted fastener is required. The metric M5x0.8 thread and DIN 7991 standard make it compatible with metric-dimensioned components in industrial, hydraulic, and mechanical systems. It is sold in multiples of 100 units, making it appropriate for production assembly or MRO restocking. The black oxide finish is commonly specified in applications where a non-reflective, oil-retentive surface is preferred over bare steel.

Key Features

• 12.9 grade alloy steel construction provides high tensile and proof load strength
• 90-degree flat head profile allows flush or countersunk installation
• 3 mm hex socket drive for precise torque application with standard hex keys
• Fully threaded M5x0.8 shank along the full 8 mm length
• Black oxide finish reduces light reflection and retains applied lubricants
• Conforms to DIN 7991 fastener standard for consistent dimensional accuracy

Compatibility

Designed as an OEM-style replacement or standard metric fastener for equipment and assemblies specifying DIN 7991 flat socket cap screws in M5x0.8 thread size.

Installation Notes

Installation should be performed by a qualified technician using a correctly sized 3 mm hex key or socket driver. Ensure the receiving material is properly countersunk to the correct 90-degree angle before driving the screw to avoid head deformation. Apply thread-locking compound or lubricant as required by the assembly specification. Confirm torque requirements with the equipment manufacturer or applicable fastener specification for 12.9 grade hardware.
