Value Collection 534118PR M8x1.25 Flat Socket Cap Screw

Product Description

The VALUE COLLECTION 534118PR is a metric flat socket cap screw designed for applications requiring a low-profile, flush-mounted fastening solution. Built to DIN 7991 standards, this M8x1.25 screw features a 90-degree flat head with a 5mm hex socket drive and runs fully threaded along its 35mm overall length. Manufactured from 12.9 grade alloy steel with a black oxide finish, it delivers high tensile strength and moderate corrosion resistance. This grade is commonly specified in precision mechanical assemblies, tooling fixtures, and industrial equipment where a countersunk, recessed fastener is required.

This screw is suited for metric fastening applications in manufacturing, machinery maintenance, and industrial assembly environments. The 12.9 material grade indicates an exceptionally high-strength fastener, appropriate for high-stress joints where standard cap screws are insufficient. The black oxide finish reduces light reflection and provides mild surface protection in dry or lightly oiled conditions. Technicians working on CNC equipment, hydraulic assemblies, mold tooling, or precision fixtures will find this screw a direct-fit for DIN 7991-compliant socket head applications.

Key Features

• DIN 7991 standard flat socket cap screw for consistent metric compliance
• M8x1.25 thread with 35mm overall length, fully threaded
• 12.9 alloy steel grade for maximum tensile and proof load strength
• 90-degree flat head profile allows flush or countersunk installation
• 5mm hex socket drive for torque application with standard Allen keys or hex bits
• Black oxide finish for reduced reflectivity and mild corrosion resistance

Compatibility

Designed for use in DIN 7991-compliant countersunk hex socket fastener applications with M8x1.25 metric threading. Suitable for any assembly specifying a 12.9 grade flat socket cap screw in this thread and length combination.

Installation Notes

Installation should be performed by a qualified technician familiar with metric fastener specifications and torque requirements for 12.9 grade hardware. De-energize and lock out all equipment before removing or replacing fasteners in any mechanical assembly. Use a correctly sized 5mm hex key or driver to avoid drive recess damage. Do not substitute lower-grade fasteners in applications engineered for 12.9 tensile ratings.
