Value Collection MKBC03C020MBPKG M3x0.5 Button Cap Screw 50pk

Product Description

The VALUE COLLECTION MKBC03C020MBPKG is a button socket cap screw designed for precision fastening applications requiring a low-profile head. Threaded M3x0.5, fully threaded along the shank, with a 20 mm length under head, this fastener meets ISO 7380 standards and carries a material grade of 10.9 for reliable tensile strength. The alloy steel construction is finished with a zinc-blue trivalent chromate coating that provides corrosion resistance while remaining RoHS and REACH compliant. Sold in a package of 50 pieces, this screw is driven with a 2 mm hex key. It is suited for technicians and tradespeople who need a code-compliant, metric fastener for panel assembly, bracket mounting, or equipment enclosure work.

This fastener is appropriate for use in residential and light commercial applications where a low-profile button head is required to clear adjacent components or reduce snag points. Common install scenarios include securing control panels, mounting brackets inside HVAC or electrical enclosures, and general equipment assembly where an M3 metric thread is specified. The fully threaded shank ensures full thread engagement across the clamped material stack. Each package contains 50 screws, making it practical for both single repairs and small production runs.

Installation Notes

Installation requires a 2 mm hex key or matching hex bit driver. De-energize any electrical enclosure or control panel before fastening or removing hardware inside live equipment, following applicable NEC or local electrical codes. Do not exceed the torque rating specified by the equipment manufacturer for M3 fasteners. Inspect threads for damage before installation to avoid cross-threading.
