Value Collection 43136 M5x0.8 Flat Socket Cap Screw 25 Pack

Product Description

The VALUE COLLECTION 43136 is a flat socket cap screw designed for applications requiring a low-profile, flush-mount fastener. Sized M5x0.8 and fully threaded along its 10.00 mm overall length, this screw conforms to DIN 7991 and is manufactured from Grade 12.9 alloy steel — one of the highest strength grades available for metric fasteners. The black oxide finish provides a baseline level of corrosion resistance and reduces light reflection, making it a practical choice in precision assemblies and machine guarding applications. Driven with a 3.00 mm hex socket, the 90-degree flat head seats flush with or below the surface of the mating material.

This screw is suited for use in mechanical assemblies, jigs and fixtures, machine components, and industrial equipment where a recessed or countersunk fastener profile is required. The M5x0.8 thread pitch follows the standard metric coarse thread series. Each package contains 25 screws, making this an efficient option for bench stock or production-run replenishment. Installation is typically performed by machinists, millwrights, or maintenance technicians working with metric hardware.

Key Features

• Grade 12.9 alloy steel construction for high tensile and proof load strength
• 90-degree flat head profile seats flush to the workpiece surface
• 3.00 mm hex socket drive for standard Allen key or hex bit installation
• Fully threaded along entire 10.00 mm length for maximum thread engagement
• Black oxide finish for mild corrosion resistance and low-reflectance appearance
• Conforms to DIN 7991 fastener standard

Compatibility

Designed as a standard DIN 7991 metric flat socket cap screw for use in any application requiring an M5x0.8 countersunk hex socket fastener with a 90-degree head angle.

Installation Notes

Installation should be performed using a calibrated torque wrench with the appropriate 3.00 mm hex bit to avoid rounding the socket drive. Ensure the countersink angle of the mating hole matches the 90-degree head angle before installation. Grade 12.9 fasteners should not be used in applications requiring weldability or in environments with sustained exposure to moisture without supplemental corrosion protection beyond black oxide. Follow applicable machine safety lockout and tagout procedures before servicing assemblies containing these fasteners.
