Value Collection MKBC04C012MBPKG M4x0.7 Button Cap Screw 50pk

Product Description

The VALUE COLLECTION MKBC04C012MBPKG is an M4x0.7 button socket cap screw manufactured from alloy steel to ISO 7380 standards and rated at material grade 10.9. Each screw features a low-profile domed button head with a 2.50 mm hex drive socket and a 12.00 mm length under the head. The fully threaded shank provides consistent thread engagement across the full grip length. The zinc-blue trivalent chromate finish delivers corrosion resistance while meeting ROHS and REACH compliance requirements. This package contains 50 screws, making it a practical stock quantity for mechanical assembly, equipment service, and panel fabrication work performed by HVAC technicians, electricians, and plumbers.

Button socket cap screws in this size are commonly used in residential and light commercial trade applications where a low-profile fastener is required in space-constrained assemblies. Typical install scenarios include equipment panel mounting, bracket attachment, and internal component fastening on HVAC units, electrical enclosures, and plumbing fixture assemblies. The hex drive interface requires a standard 2.50 mm hex key or Allen driver, which is a common tool in most trade kits. The 50-count package suits bench stock replenishment and service van inventories.

Installation Notes

Installation should be performed with a properly sized 2.50 mm hex key or driver bit to avoid rounding the drive socket. De-energize any electrical equipment and shut off all fluid or refrigerant circuits before accessing fastened components. Do not mix fastener grades in structural or pressure-bearing assemblies. Follow applicable equipment manufacturer torque guidelines and relevant codes such as NEC or IFGC where fastener selection affects code-governed assemblies.
