Value Collection MKCS03C0359MBPKG M3x0.5 Socket Cap Screw 25pk

Product Description

The VALUE COLLECTION MKCS03C0359MBPKG is a partially threaded socket cap screw with an M3x0.5 thread profile and a 35 mm length under the head. Made from alloy steel to material grade 12.9, it delivers high tensile strength suitable for demanding fastening applications in mechanical assemblies, fixtures, and equipment. The hex drive accepts a 2.5 mm hex key for precise torque application in tight spaces. The zinc-blue trivalent chromate finish provides corrosion resistance and is RoHS and REACH compliant. Sold in a package of 25 pieces, this screw is a standard choice for maintenance technicians, millwrights, and equipment assemblers working to DIN 912 and ISO 4762 standards.

These socket cap screws are suited for residential and commercial mechanical assemblies where a compact, high-strength fastener is required. The M3x0.5 coarse thread and partial threading make them appropriate for through-hole applications and installations where a smooth shank section is needed for alignment or shear loading. Typical use cases include panel mounting, machinery assembly, and equipment maintenance across HVAC, plumbing, and electrical trade applications.

Key Features

• M3x0.5 coarse right-hand thread for standard metric fastening
• Partially threaded shank allows use in through-hole and shear-load installations
• Alloy steel grade 12.9 construction provides high tensile and proof load ratings
• 2.5 mm internal hex drive for use in confined spaces with standard hex keys
• Zinc-blue trivalent chromate finish for corrosion resistance; RoHS and REACH compliant
• Conforms to DIN 912 and ISO 4762 fastener standards

Compatibility

Designed as an OEM-style replacement or maintenance fastener for metric threaded assemblies requiring an M3x0.5 socket cap screw per DIN 912 or ISO 4762 specifications.

Installation Notes

Installation is performed with a 2.5 mm hex key or hex bit driver. De-energize and lock out any equipment before disassembling fastened components. Do not exceed the torque rating for grade 12.9 M3 fasteners as specified by the equipment manufacturer or applicable assembly standards. Inspect threads and mating holes for damage or contamination before installation.
