Value Collection MKCS03C0059MBPKG M3x0.5 Socket Cap Screw 100pk

Product Description

The VALUE COLLECTION MKCS03C0059MBPKG is an M3x0.5 socket cap screw designed for high-strength fastening in mechanical assemblies, equipment enclosures, and precision fixtures. Manufactured from grade 12.9 alloy steel and finished with a zinc-blue trivalent chromate coating, this fastener delivers strong clamping force with solid corrosion resistance. The fully threaded shank runs the entire 5 mm length under the head, providing maximum thread engagement in shallow or thin-material applications. A 2.5 mm hex drive socket accepts a standard hex key for consistent, controlled torque. This package contains 100 screws and ships as a single unit.

This screw is suited for light-duty to high-strength bolted connections in industrial machinery, HVAC equipment panels, electrical enclosures, and precision mechanical components. The coarse M3x0.5 thread pitch is the standard metric coarse designation for 3 mm fasteners, making it widely compatible with tapped holes in steel, aluminum, and engineered plastics. The trivalent chromate finish meets RoHS and REACH compliance requirements, making it appropriate for use in environmentally regulated assemblies and export equipment.

Key Features

• Grade 12.9 alloy steel construction for high tensile and proof load strength
• Fully threaded from tip to underside of head for maximum thread engagement
• Zinc-blue trivalent chromate finish provides corrosion resistance and RoHS/REACH compliance
• 2.5 mm internal hex drive for precise torque application with standard hex keys
• Right-hand coarse thread (M3x0.5) per DIN 912 and ISO 4762 fastener standards
• Sold in a 100-piece package for bench stock and service kit replenishment

Compatibility

Designed as a standard metric socket cap screw per DIN 912 and ISO 4762, compatible with any M3x0.5 coarse-thread tapped hole in steel, aluminum, or compatible engineered materials.

Installation Notes

Installation is performed with a 2.5 mm hex key or hex bit driver. Verify the mating tapped hole thread pitch matches M3x0.5 coarse before installation. For grade 12.9 fasteners, follow the equipment manufacturer torque specifications for the fastener class and joint material. Always de-energize or shut down any equipment before accessing internal fastened assemblies.
