Value Collection 534110PR M8x1.25 Flat Socket Cap Screw

Product Description

The VALUE COLLECTION 534110PR is a metric flat socket cap screw machined from 12.9 grade alloy steel with a black oxide finish. It features a 90-degree flat head driven by a 5 mm hex socket and is fully threaded along its 16 mm overall length. The M8x1.25 thread size and DIN 7991 standard make this screw a precise-fit fastener suited for flush or countersunk assemblies where a low-profile head is required. Machinists, millwrights, and maintenance technicians install this type of fastener in mechanical equipment, fixtures, and structural assemblies where high tensile strength and a clean seating surface are critical.

This screw is used in applications that demand a countersunk fastener with maximum clamping force. The 12.9 material grade delivers high tensile and proof load strength, making it appropriate for demanding industrial and mechanical assemblies. Black oxide finish provides mild corrosion resistance and reduces light reflection on exposed hardware. Typical installation environments include machine tool fixtures, equipment frames, and fabricated metal assemblies requiring metric DIN-standard fasteners.

Key Features

• 12.9 grade alloy steel construction for high tensile strength
• 90-degree flat head profile for flush countersunk installation
• 5 mm hex socket drive for positive torque engagement
• Fully threaded M8x1.25 shank along entire 16 mm length
• Black oxide finish for mild corrosion resistance and low reflectivity
• Conforms to DIN 7991 fastener standard

Compatibility

Designed as a DIN 7991 metric flat socket cap screw compatible with M8x1.25 countersunk threaded holes in standard metric assemblies and fixtures.

Installation Notes

Installation is performed by machinists, millwrights, or maintenance technicians using a 5 mm hex key or socket driver. Ensure the mating countersink angle matches the 90-degree head geometry before installation to achieve proper flush seating. Power down and de-energize any equipment before servicing fasteners in live assemblies. Apply thread lubricant or anti-seize compound as appropriate for the application to achieve accurate torque results.
