Value Collection 534114P Flat Socket Cap Screw M8x1.25

Product Description

The VALUE COLLECTION 534114P is a flat socket cap screw engineered for high-strength metric fastening applications. It features an M8x1.25 thread size with a 25 mm overall length and is fully threaded along its entire shank. The 90-degree flat head profile sits flush with or below the mating surface, making it well suited for assemblies where a low-profile or countersunk fastener is required. The hex socket drive accepts a 5 mm hex key for installation and removal. Manufactured from 12.9 grade alloy steel with a black oxide finish, this screw delivers high tensile strength and moderate corrosion resistance in service environments typical of industrial and mechanical assemblies.

This fastener is used in applications that require a flush or countersunk fastener seating, including machine frames, jigs, fixtures, tooling plates, and precision mechanical assemblies. The 12.9 material grade indicates a high-strength classification suitable for joints with significant clamping force requirements. It is appropriate for use by machinists, maintenance technicians, and industrial assembly professionals working with metric-dimensioned components.

Key Features

• 90-degree flat head seats flush or countersunk into mating material
• M8x1.25 metric thread, fully threaded over 25 mm overall length
• 12.9 alloy steel grade provides high tensile and proof load strength
• Black oxide finish reduces light reflection and provides mild corrosion protection
• 5 mm hex socket drive for standard hex key installation
• Conforms to DIN 7991 fastener standard

Compatibility

Designed as a metric flat socket cap screw per DIN 7991, compatible with M8x1.25 threaded holes in metal components requiring a countersunk or flush-head fastener.

Installation Notes

Installation should be performed by a qualified machinist or mechanical technician using a properly sized 5 mm hex key or socket driver. Confirm that the mating countersink angle matches the 90-degree head geometry before installation to ensure full bearing contact. Torque to the value specified by the joint design engineer based on the material grade and application requirements. Always inspect threads for damage before installation and replace any screw showing signs of galling or deformation.
