Value Collection 534056P M5x0.8 Flat Socket Cap Screw 12.9

Product Description

The VALUE COLLECTION 534056P is a metric flat socket cap screw engineered for precision fastening applications requiring a low-profile, flush-mount head. Built from 12.9 grade alloy steel with a black oxide finish, this screw delivers high tensile strength and moderate corrosion resistance in a compact form. The 90-degree flat head seats flush with the mating surface, making it suitable for assemblies where clearance is tight or appearance matters. Driven by a 3.00 mm hex socket, it is fully threaded along its 20 mm overall length. Manufactured to DIN 7991 standards, it is a reliable choice for maintenance professionals, machinists, and fabricators working with metric fastener specifications.

This flat socket cap screw is used in mechanical assemblies, industrial equipment, and precision machinery where a countersunk, flush-seated fastener is required. The fully threaded M5x0.8 shank provides strong thread engagement across the full fastener length, which is especially useful in thin-stock applications or where a nut is used without a tapped bore. Typical applications include jigs, fixtures, panels, and machine guards. Installation is performed using a standard 3.00 mm hex key or Allen driver.

Key Features

• 90-degree flat head seats flush with the mating surface for low-profile, countersunk installations
• 12.9 grade alloy steel provides high tensile and proof load strength
• Black oxide finish offers mild corrosion resistance and reduces light reflection
• Fully threaded along the entire 20 mm length for maximum thread engagement
• Conforms to DIN 7991 fastener standard for consistent dimensional accuracy
• Hex socket drive (3.00 mm) allows installation in confined spaces with a standard hex key

Compatibility

Designed as an OEM-style or maintenance replacement flat socket cap screw for metric-threaded assemblies requiring an M5x0.8 countersunk fastener per DIN 7991.

Installation Notes

Installation should be performed by a qualified mechanic or maintenance technician using a calibrated 3.00 mm hex key or torque-limiting driver appropriate for 12.9 grade fasteners. Ensure the mating countersink is machined to the correct 90-degree included angle before installation. De-energize and lock out all power sources on the equipment before removing or replacing fasteners in live assemblies. Do not mix metric and inch-series fasteners in the same tapped hole.
