Value Collection 565049PS M5x0.8 Button Socket Cap Screw

Product Description

The VALUE COLLECTION 565049PS is a fully threaded button socket cap screw designed for metric fastening applications requiring a low-profile head and high clamping strength. Manufactured from alloy steel at material grade 12.9, it delivers a hardness of 38-43 HRC, making it suitable for demanding structural and mechanical assemblies. The black oxide coating provides mild corrosion resistance and a clean, finished appearance. The hex socket drive accepts a 3 mm hex key for installation in confined spaces where a standard external-drive tool cannot reach. This fastener is sold in multiples of 100.

This screw is used in light machinery, equipment enclosures, jigs, fixtures, and general mechanical assemblies where a flush or near-flush head profile is preferred over a standard hex cap screw. The M5x0.8 thread and 8 mm length under head make it well suited for thin panel attachment and component mounting applications common in industrial and trade maintenance work. It conforms to ANSI/ASME B18.3.4M and ISO 7380 standards, ensuring dimensional interchangeability with other compliant metric fasteners.

Key Features

• Alloy steel construction at grade 12.9 with 38-43 HRC hardness for high tensile strength
• Button head profile provides a low-profile, rounded appearance and distributes clamping load over a wider bearing surface
• 3 mm hex socket drive allows installation in tight clearance areas
• Black oxide finish offers mild corrosion resistance and reduces light reflection
• Fully threaded M5x0.8 metric thread with right-hand direction and 4G/6G fit class
• Meets ANSI/ASME B18.3.4M and ISO 7380 fastener standards

Compatibility

Designed as a standard metric replacement or stock fastener for any assembly requiring an M5x0.8 button socket cap screw conforming to ISO 7380 and ANSI/ASME B18.3.4M dimensional standards.

Installation Notes

Install with a 3 mm hex key or hex bit driver; ensure the drive tool is fully seated to avoid rounding the socket. Confirm mating thread class and material compatibility before installation in structural applications. Grade 12.9 fasteners should not be substituted with lower-grade hardware in torque-critical joints. Follow applicable mechanical assembly standards and equipment manufacturer specifications when determining fastener torque.
