Value Collection 534200PS Flat Socket Cap Screw M12x1.75

Product Description

The VALUE COLLECTION 534200PS is a metric flat socket cap screw designed for flush or countersunk fastening applications where a low-profile head is required. Built to DIN 7991 specification from 12.9 grade alloy steel with a black oxide finish, this fastener delivers high tensile strength and moderate corrosion resistance in a compact form. The 90-degree flat head and 8 mm hex socket drive allow precise torque application in recessed or tight-clearance installations. Machinists, millwrights, and mechanical assembly technicians are the primary installers of this type of fastener.

This screw is suited for general industrial, machine tool, and mechanical assembly applications requiring a fully threaded metric fastener. The M12x1.75 thread size and 40 mm overall length make it appropriate for medium-load countersunk joints in steel, aluminum, and similar structural materials. The black oxide finish reduces galling and provides a uniform appearance. It is commonly used in manufacturing fixtures, equipment enclosures, and precision mechanical assemblies where a hex socket drive is preferred for torque control.

Key Features

• DIN 7991 standard for consistent dimensional accuracy and interchangeability
• 12.9 grade alloy steel construction for high tensile and proof load capacity
• 90-degree flat head profile allows flush or countersunk installation
• 8 mm hex socket drive compatible with standard metric hex keys and bits
• Black oxide finish reduces surface friction and provides mild corrosion resistance
• Fully threaded along the 40 mm overall length for maximum thread engagement

Compatibility

Designed as a DIN 7991 metric flat socket cap screw for standard M12x1.75 countersunk fastener applications in industrial and mechanical assembly environments.

Installation Notes

Installation is performed by machinists, millwrights, or qualified mechanical assemblers using a calibrated torque wrench and an 8 mm hex socket key. Ensure the mating countersink angle matches the 90-degree flat head geometry before seating the fastener. De-energize and lock out all equipment before fastener replacement or installation on live machinery. Avoid impact driving, which can damage the hex socket recess or exceed the material's proof load.
