Value Collection 534052P M5x0.8 Flat Socket Cap Screw 12.9

Product Description

The VALUE COLLECTION 534052P is a metric flat socket cap screw designed for applications requiring a low-profile, flush-mount fastener with high tensile strength. Built from 12.9 grade alloy steel with a black oxide finish, this screw delivers superior clamping force in confined spaces where a protruding head is not acceptable. The 90-degree flat head seats flush with or below the mating surface when installed in a countersunk hole. Drive engagement is accomplished with a 3.00 mm hex socket key. The fully threaded M5x0.8 shank runs the entire 12 mm overall length, maximizing thread engagement in shallow blind holes or thin workpieces.

This fastener is suited for mechanical assemblies, tooling fixtures, machine components, and precision equipment where a flat countersunk head is required. The black oxide finish provides mild corrosion resistance and reduces light reflection, making it a common choice in industrial machinery, jigs, and instrument enclosures. Installation is performed by machinists, millwrights, and maintenance technicians working with metric hardware.

Key Features

• 12.9 alloy steel grade provides high tensile and proof load strength for demanding clamping applications
• 90-degree flat head profile allows flush or sub-flush seating in countersunk holes
• 3.00 mm hex socket drive for positive torque transfer with a standard Allen key
• Fully threaded M5x0.8 shank across the full 12 mm length maximizes thread engagement
• Black oxide finish offers mild corrosion resistance and a low-reflectance appearance
• Conforms to DIN 7991 fastener standard for dimensional consistency

Compatibility

Designed as a standard metric replacement or service fastener for any assembly requiring a DIN 7991 M5x0.8 flat socket cap screw with a 90-degree countersunk head.

Installation Notes

Installation should be performed by a qualified technician familiar with metric fastener specifications. The mating component must have a properly dimensioned 90-degree countersunk hole to achieve full flush seating and correct load distribution. Use a calibrated torque wrench with a 3.00 mm hex socket bit and apply torque values appropriate for 12.9 grade M5 fasteners as specified by the equipment manufacturer or applicable engineering standard. Never reuse fasteners that show signs of galling, corrosion, or drive damage.
