Metric 12.9 ISO 7380 Button Head Socket Head Cap Screws with Thermal Black Oxide Plating
Metric 12.9 ISO 7380 Button Head Socket Head Cap Screws with Thermal Black Oxide Plating
Metric 12.9 ISO 7380 Button Head Socket Head Cap Screws with Thermal Black Oxide Plating are high-strength metric fasteners designed for applications requiring excellent mechanical performance, a low-profile head, and a clean finished appearance. Manufactured to ISO 7380 dimensional requirements, these button head socket screws feature an internal hex drive that allows efficient installation where external wrench clearance may be limited.
The rounded button head design provides a lower profile than conventional socket head cap screws while distributing the head over a larger bearing surface. These characteristics make ISO 7380 button head screws popular for machinery, industrial equipment, automation systems, automotive assemblies, fabrication, and OEM applications.
Property Class 12.9 High-Strength Fasteners
The Metric 12.9 property class identifies a high-strength alloy steel fastener designed for demanding mechanical assemblies. Class 12.9 screws provide high tensile and yield strength, making them suitable for applications involving substantial clamping forces and mechanical loads.
Proper torque values should always be determined according to fastener diameter, thread pitch, lubrication, mating materials, and application requirements.
ISO 7380 Button Head and Hex Socket Drive
The ISO 7380 button head configuration provides a smooth, rounded appearance with reduced head height. An internal hex socket drive provides positive tool engagement and makes installation convenient in confined assemblies.
Thermal Black Oxide Plating
Thermal black oxide plating gives these metric socket screws a distinctive dark finish while providing mild corrosion protection and helping improve appearance. Black oxide also produces minimal dimensional buildup compared with heavier coatings, an advantage for precision threaded fasteners.
For applications requiring high strength, compact head geometry, and professional appearance, Metric 12.9 ISO 7380 Button Head Socket Head Cap Screws with Thermal Black Oxide Plating provide an excellent fastening solution for industrial machinery, equipment manufacturing, fabrication, maintenance, and OEM assembly.
