Value Collection BHS7X08040-100BX M8x1.25 Button Cap Screw

Product Description

The VALUE COLLECTION BHS7X08040-100BX is a metric button socket cap screw manufactured from A2 (18-8) stainless steel with a bright, uncoated finish. It features an M8x1.25 thread and a 40 mm length under the head, conforming to ANSI/ASME B18.3.4M and ISO 7380 standards. The low-profile button head is driven by a 5 mm hex socket. The partially threaded shank and 6G thread fit class make this fastener well-suited for precision assemblies where corrosion resistance and a clean head profile are required. Machinists, millwrights, fabricators, and maintenance technicians install these in metal-to-metal and sheet-metal applications across industrial, commercial, and light mechanical settings.

This screw is commonly used in machine guards, enclosures, brackets, and structural assemblies where a flush or low-profile head is preferred over a standard hex cap or socket head cap screw. The right-hand metric thread and ISO 7380 compliance make it compatible with standard metric tapped holes and insert nuts. It is appropriate for both indoor and outdoor service environments where mild-to-moderate corrosion resistance is needed, given the A2 stainless steel construction.

Key Features

• A2 (18-8) stainless steel construction provides corrosion resistance for indoor and outdoor use
• Low-profile button head reduces snag risk and suits flush-clearance assemblies
• 5 mm hex socket drive for standard hex key or socket bit installation
• M8x1.25 right-hand thread with 6G fit class for consistent engagement in metric tapped holes
• Conforms to ANSI/ASME B18.3.4M and ISO 7380 dimensional standards
• Bright, uncoated finish maintains as-manufactured dimensional tolerances

Compatibility

Designed as a standard ISO 7380 metric button socket cap screw for use in M8x1.25 tapped holes. Suitable for general-purpose metric fastening applications requiring an A2 stainless steel, low-profile button head fastener.

Installation Notes

Install with a 5 mm hex key or hex bit driver. Verify the mating tapped hole or nut meets M8x1.25 metric thread specifications before installation. Do not exceed the mechanical load limits appropriate for A2 stainless steel; consult applicable engineering standards when used in structural or load-bearing joints. Ensure mating surfaces are clean and free of debris to achieve proper thread engagement.
