Value Collection MKBC04C025MBPKG M4x0.7 Button Cap Screw 50pk

Product Description

The VALUE COLLECTION MKBC04C025MBPKG is a button socket cap screw designed for mechanical assemblies where a low-profile head and high clamping strength are required. Manufactured from alloy steel to material grade 10.9, this fastener delivers the tensile strength needed for demanding applications. It carries an M4x0.7 thread specification with a 25 mm length under the head and is fully threaded along its shank. The zinc-blue trivalent chromate finish provides corrosion resistance while meeting ROHS and REACH compliance requirements. Each package contains 50 screws conforming to ISO 7380 fastener standards. Licensed trade professionals and maintenance technicians will find this fastener suited to precision equipment work.

This button socket cap screw is commonly used in HVAC equipment panels, electrical enclosures, pump housings, pool equipment frames, and general mechanical assemblies where clearance above the fastener head is limited. The low-dome button head profile reduces interference with adjacent components. The hex drive socket accepts a 2.50 mm hex key, making installation accessible in confined spaces. Fully threaded construction ensures maximum thread engagement across the full shank length, which is particularly useful in thin-material applications.

Key Features

• M4x0.7 thread with 25 mm length under head for precise fitment in standard metric applications
• Alloy steel construction at material grade 10.9 for high tensile and proof load strength
• Fully threaded shank maximizes thread engagement in thin panels and brackets
• Zinc-blue trivalent chromate finish provides corrosion resistance and meets ROHS and REACH compliance
• Conforms to ISO 7380 fastener standard for dimensional consistency
• Package of 50 screws minimizes restocking frequency on active job sites

Compatibility

Designed as a standard ISO 7380 metric button socket cap screw suitable for M4x0.7 threaded applications in mechanical, electrical, and HVAC equipment assemblies.

Installation Notes

Installation is performed with a 2.50 mm hex key or matching hex bit driver. De-energize and lock out any electrical or mechanical equipment before fastener service. Apply appropriate torque for grade 10.9 M4 fasteners per the equipment manufacturer specifications or applicable mechanical codes. Avoid overtightening, which can strip threads in aluminum or thin sheet-metal base materials.
