Value Collection 41918 M5x0.80 Button Socket Cap Screw

Product Description

The VALUE COLLECTION 41918 is a metric button socket cap screw designed for precision fastening in mechanical assemblies, tooling fixtures, and equipment fabrication. It features an M5x0.80 thread and a 20mm length under the head, with a low-profile button head that provides a smooth, rounded surface when installed. Drive engagement is via a 3mm hex socket. The screw is manufactured from Grade 10.9 alloy steel, placing it in the high-strength class for metric fasteners, and is finished in black oxide for mild corrosion resistance. Fully threaded along the shank, it is suited for through-hole and threaded-insert applications. Licensed tradespeople and machine technicians working in tight-clearance environments will find the button head geometry especially practical.

This fastener is appropriate for light to medium-duty mechanical assemblies where a flush or near-flush head profile is required. Common applications include panel attachment, machinery guards, jig and fixture construction, and electronic enclosures. The metric thread form and ISO 7380 fastener standard make it compatible with globally sourced components and equipment. The black oxide finish is suitable for indoor or controlled-environment installations where appearance and mild surface protection are priorities. It is sold in multiples of 25 units per order.

Key Features

• Grade 10.9 alloy steel construction for high tensile strength in a compact fastener
• Button head profile minimizes protrusion and suits flush or near-flush installations
• 3mm hex socket drive for precise torque application with standard Allen keys or hex bit drivers
• Black oxide finish provides mild corrosion resistance and a clean appearance
• Fully threaded shank suits through-hole and threaded-insert applications
• Conforms to ISO 7380 fastener standard with 4G and 6G thread fit classes

Compatibility

Designed as an ISO 7380-compliant M5x0.80 metric button socket cap screw suitable for use in any application requiring a Grade 10.9 alloy steel fastener of this thread size and head type.

Installation Notes

Installation requires a 3mm hex key or hex socket bit driver. Verify that the mating thread is clean and free of debris before driving. Apply appropriate torque per the assembly specification for Grade 10.9 M5 fasteners. Black oxide finish does not substitute for dedicated corrosion-protection coatings in wet or outdoor environments.
