Value Collection MKBC03C010MBPKG M3x0.5 Button Cap Screw 50pk

Product Description

The VALUE COLLECTION MKBC03C010MBPKG is an M3x0.5 button socket cap screw designed for applications requiring a low-profile head and reliable clamping force. Manufactured from alloy steel to material grade 10.9, this fastener delivers high tensile strength suitable for demanding mechanical assemblies. The hex drive socket accepts a 2.00 mm hex key for installation in confined spaces where a standard hex head would not fit. A zinc-blue trivalent chromate finish provides corrosion resistance while meeting RoHS and REACH compliance requirements. This package contains 50 screws, making it well suited for production runs, field service kits, or bench stock replenishment.

Button socket cap screws in M3x0.5 with a 10 mm length under head are widely used in light mechanical assemblies, electronic enclosures, HVAC equipment panels, and precision instrument housings. The low-profile domed button head distributes clamping load over a wider bearing surface compared to a standard socket head cap screw, reducing the risk of surface damage on thinner substrates. Electricians, HVAC technicians, and mechanical assemblers commonly specify this fastener type when clearance above the joint surface is limited. The fully threaded shank ensures maximum thread engagement across the full grip length.

Key Features

• M3x0.5 fully threaded alloy steel construction to material grade 10.9 for high tensile strength
• Low-profile button head reduces above-surface protrusion in tight clearance assemblies
• 2.00 mm hex drive socket allows installation with a standard hex key or hex bit driver
• Zinc-blue trivalent chromate finish provides corrosion resistance and meets RoHS and REACH compliance
• Conforms to ISO 7380 fastener standard
• Package of 50 screws supports production, service kit, and bench stock applications

Compatibility

Designed as a standard ISO 7380 M3x0.5 button socket cap screw suitable for use in any threaded M3x0.5 female thread application requiring a low-profile head and 10 mm length under head.

Installation Notes

Install using a calibrated 2.00 mm hex key or hex bit driver; do not use an undersized key as it may round the drive socket. Confirm the mating thread is clean and free of debris before installation. Apply thread-locking compound only if specified by the equipment manufacturer, as the grade 10.9 alloy steel shank may be susceptible to hydrogen embrittlement with certain chemical compounds. Follow applicable mechanical assembly standards and equipment service documentation for torque requirements.
