Value Collection 1-MBS-8-30 Button Socket Cap Screw M8x1.25

Product Description

The VALUE COLLECTION 1-MBS-8-30 is a partially threaded button socket cap screw designed for metric fastening applications requiring a low-profile head and a clean, corrosion-resistant finish. Manufactured from A2 (18-8) stainless steel with a bright, uncoated surface, this fastener conforms to ANSI/ASME B18.3.4M and ISO 7380 standards. The M8x1.25 thread size with a 30mm length under head suits a wide range of structural and mechanical assembly tasks. The hex socket drive requires a 5mm hex key for installation and provides reliable torque transfer in confined or flush-clearance spaces.

This button socket cap screw is well suited for light to medium-duty mechanical assemblies where a low-profile head is preferred over a standard hex cap or socket head. Common applications include machine frames, enclosures, panel mounting, and general fabrication work in industrial, commercial, and maintenance environments. The right-hand thread direction and 6G thread fit class ensure compatibility with standard metric tapped holes. Machinists, maintenance technicians, and fabricators are the primary users of this fastener type.

Key Features

• Low-profile button head provides flush or near-flush installation in clearance-sensitive assemblies
• A2 (18-8) stainless steel construction offers good corrosion resistance for indoor and moderate outdoor use
• Conforms to ANSI/ASME B18.3.4M and ISO 7380 standards for dimensional consistency
• 5mm hex socket drive for reliable torque application with standard hex keys or drivers
• Right-hand, 6G thread fit class for compatibility with standard metric tapped holes
• Bright, uncoated finish suitable for applications where paint or coating buildup is undesirable

Compatibility

Designed as a standard metric replacement or stock fastener for assemblies using M8x1.25 partially threaded button socket cap screws per ISO 7380 and ANSI/ASME B18.3.4M specifications.

Installation Notes

Installation is performed with a 5mm hex key or socket driver; verify the mating tapped hole meets M8x1.25 metric thread specifications before installation. Ensure the receiving material and thread depth are adequate for the applied load before torquing. Avoid mixing stainless steel fasteners with dissimilar metals in environments prone to galvanic corrosion. Minimum order quantity is 100 units per order.
