Value Collection 43162 Flat Socket Cap Screw M8x1.25

Product Description

The VALUE COLLECTION 43162 is a flat socket cap screw engineered for precision fastening applications where a flush or countersunk head profile is required. Manufactured from 12.9 grade alloy steel with a black oxide finish, this screw delivers high tensile strength and moderate corrosion resistance in a low-profile form factor. The M8x1.25 thread size and 50 mm overall length make it a common choice in mechanical assemblies, machine frames, and tooling fixtures. Installation is performed with a 5 mm hex socket (Allen) key. The partial threading allows for controlled clamping force and is consistent with DIN 7991 dimensional standards.

This flat socket cap screw is suited for metric mechanical assemblies in manufacturing, industrial equipment, and precision fabrication environments. The 90-degree flat head seats flush into countersunk holes, making it appropriate for applications where protruding fastener heads are not acceptable. It is typically installed by machinists, maintenance technicians, and mechanical assemblers working on metal-to-metal joints where high-strength fasteners are specified.

Key Features

• 12.9 grade alloy steel construction for high tensile and proof load strength
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• 90-degree flat head seats flush in standard countersunk holes per DIN 7991
• 5 mm hex socket drive for precise torque application with common Allen tooling
• Partial threading supports accurate clamping in thick-material applications
• Metric thread standard M8x1.25 with 50 mm overall length

Compatibility

Designed as a DIN 7991 metric flat socket cap screw suitable for countersunk M8 metric threaded holes in industrial and mechanical assembly applications.

Installation Notes

Installation requires a 5 mm hex key or socket driver. Ensure the mating countersunk hole is machined to the appropriate 90-degree angle to achieve full head seating. Verify thread engagement depth meets design requirements before final torque. Always degrease mating surfaces and inspect threads for damage prior to assembly.
