Value Collection 534006PR M3x0.5 Flat Socket Cap Screw

Product Description

The VALUE COLLECTION 534006PR is a metric flat socket cap screw engineered for applications where a flush or countersunk fastener profile is required. Built to DIN 7991 standards, this screw features an M3x0.5 thread, an 8 mm overall length, and a 90-degree flat head driven by a 2 mm hex socket. The 12.9 material grade alloy steel construction delivers high tensile strength, making it suitable for precision assemblies, tooling fixtures, and mechanical subassemblies where standard socket head cap screws are too tall. The black oxide finish provides mild corrosion resistance and reduces surface reflectivity. Licensed trade professionals and precision assembly technicians install this fastener across a range of industrial and mechanical applications.

This screw is used in metric-dimensioned assemblies requiring a low-profile, fully threaded fastener. Typical applications include machine guarding, fixture plates, electronic enclosures, hydraulic component mounting, and general mechanical assembly where head protrusion must be minimized. The fully threaded shank allows engagement along the entire fastener length, which is advantageous in thin-material or short-depth threaded hole installations. This part is sold individually but carries a minimum order quantity of 100 units, making it appropriate for production and MRO procurement.

Key Features

• DIN 7991 standard — ensures dimensional interchangeability with metric tooling and hardware
• 12.9 alloy steel grade — high tensile and proof load strength for demanding fastening applications
• 90-degree flat head with 2 mm hex socket drive — allows flush or countersunk installation
• M3x0.5 fully threaded shank — full thread engagement from head to tip
• Black oxide finish — mild corrosion resistance with low-reflectivity surface
• 8 mm overall length — compact profile suited for thin-section assemblies

Compatibility

Designed for use in any metric-threaded application requiring a DIN 7991 flat socket cap screw with an M3x0.5 thread and 8 mm overall length.

Installation Notes

Installation requires a 2 mm hex key or socket driver; use of a calibrated torque wrench is recommended to avoid stripping the socket or overloading the threaded hole. Ensure the mating countersink is machined to the correct 90-degree angle to achieve full head seating. As with all 12.9-grade fasteners, avoid hydrogen embrittlement risk by not welding near installed screws. Power down or de-energize any equipment before accessing fastener locations on live assemblies.
