Value Collection 534036PR M4x0.7 Flat Socket Cap Screw

Product Description

The VALUE COLLECTION 534036PR is an M4x0.7 flat socket cap screw machined from 12.9 grade alloy steel with a black oxide finish. The 90-degree flat head profile seats flush with or below the mating surface, eliminating protrusion in countersunk hole applications. The internal hex socket drive accepts a 2.5 mm hex key for precise torque application in confined spaces. Partial threading along the 35 mm overall length provides a smooth shank section for shear-load applications. This fastener is manufactured to DIN 7991 dimensional standards and is sold in multiples of 100.

This screw is suited for machine assemblies, tooling fixtures, and precision equipment where a flush or recessed fastener profile is required. The 12.9 material grade indicates very high tensile strength, making it appropriate for high-stress mechanical joints in industrial and manufacturing environments. The black oxide finish provides mild corrosion resistance and reduces light reflection, which is useful in optical or electronic equipment enclosures. Licensed machinists, millwrights, and precision assembly technicians are the primary installers.

Key Features

• 90-degree flat head seats flush in countersunk holes per DIN 7991
• 12.9 alloy steel grade for high tensile and proof load requirements
• 2.5 mm hex socket drive for use with standard metric hex keys
• Partial threading preserves a smooth shank for shear-load applications
• Black oxide finish for mild corrosion resistance and low-reflectance appearance
• Metric thread standard M4x0.7 for compatibility with standard metric tapped holes

Compatibility

Designed as an OEM-style replacement or stock fastener for metric-threaded M4x0.7 countersunk hole applications conforming to DIN 7991 dimensional requirements.

Installation Notes

Installation requires a 2.5 mm hex key or hex socket bit rated for the torque demands of a 12.9 grade fastener. Power down all equipment and relieve any mechanical load before removing or replacing structural fasteners. Verify the mating thread is clean and the countersink angle matches the 90-degree head geometry before fully seating the screw. Do not substitute a lower-grade fastener in joints originally specified for 12.9 material.
