Value Collection MKCS03C0169MBPKG M3x0.5 Socket Cap Screw 100pk

Product Description

The VALUE COLLECTION MKCS03C0169MBPKG is a fully threaded M3x0.5 socket cap screw manufactured from alloy steel with a zinc-blue trivalent chromate finish. At 16 mm in length under the head and a 5.5 mm head diameter, this screw is driven with a 2.5 mm hex key. The grade 12.9 alloy steel construction delivers high tensile strength and fatigue resistance, making it suited for demanding mechanical assemblies. The trivalent chromate coating provides corrosion protection and meets RoHS and REACH compliance requirements. Each package contains 100 screws, supplied in multiples of 1. This fastener is installed by HVAC technicians, plumbers, electricians, and mechanical contractors in equipment assembly and service applications.

M3x0.5 socket cap screws in grade 12.9 alloy steel are commonly used in tight-clearance assemblies where a low-profile head and high clamp load are required. Typical applications include securing panels, brackets, motor mounts, and equipment housings in residential and light commercial HVAC units, electrical enclosures, pump assemblies, and similar mechanical systems. The coarse right-hand thread and hex drive allow reliable installation in confined spaces where a torque wrench or hex key is the only tool that fits.

Key Features

• Grade 12.9 alloy steel for high tensile strength in demanding assemblies
• Fully threaded M3x0.5 coarse right-hand thread for maximum thread engagement
• 2.5 mm hex drive accommodates standard hex keys and Allen drivers
• Zinc-blue trivalent chromate finish provides corrosion resistance
• RoHS and REACH compliant coating for environmentally regulated applications

• Sold in a 100-count package to support batch service and assembly work

Compatibility

Designed as a standard DIN 912 and ISO 4762 socket cap screw for any M3x0.5 threaded application requiring a grade 12.9 alloy steel fastener with a hex drive.

Installation Notes

Installation is performed by qualified mechanical, HVAC, or electrical technicians using a 2.5 mm hex key or Allen driver. De-energize all equipment and relieve any system pressure before disassembling fastened components. Do not mix fastener grades in the same joint, and do not reuse fasteners that show signs of thread damage or deformation. Follow applicable equipment manufacturer torque specifications and relevant code requirements for the system being serviced.
