Value Collection BHS7X05040-025BX M5x0.8 Button Cap Screw

Product Description

The VALUE COLLECTION BHS7X05040-025BX is a partially threaded button socket cap screw designed for metric fastening applications requiring a low-profile head and internal hex drive. Built from A2 (18-8) stainless steel with a bright, uncoated finish, it offers solid corrosion resistance in general industrial and mechanical assembly environments. The M5x0.8 thread with a 40 mm length under head and 3 mm hex socket drive suits applications where a smooth, rounded head is required to clear adjacent components or protect mating surfaces. This fastener conforms to ANSI/ASME B18.3.4M and ISO 7380 standards. Sold in a minimum order quantity of 25 pieces per box, it is a practical stock item for maintenance shops, machine builders, and fabrication crews.

This button socket cap screw is suited for light to medium clamping loads in mechanical assemblies, panel mounting, and equipment fabrication where the button-head profile reduces snag points and protrusion. The metric M5x0.8 thread pattern makes it appropriate for use in machine frames, enclosures, brackets, and similar metalwork requiring ISO-standard fasteners. Installation is performed with a standard 3 mm hex key or hex socket driver. The 6G thread fit class ensures consistent engagement with standard M5 metric threaded holes and inserts across a wide range of applications.

Key Features

• A2 (18-8) stainless steel construction provides corrosion resistance without a surface coating
• Low-profile button head reduces snag risk and protrusion in finished assemblies
• ISO 7380 and ANSI/ASME B18.3.4M compliant for use in standardized metric fastening applications
• 3 mm hex socket drive compatible with standard hex keys and bit drivers
• 6G thread fit class for reliable engagement with standard M5 metric threaded holes
• Packaged in quantities of 25 for efficient shop stocking and job-site use

Compatibility

Designed as an ISO 7380 and ANSI/ASME B18.3.4M compliant metric fastener for use in any application requiring an M5x0.8 partially threaded button socket cap screw in A2 stainless steel.

Installation Notes

Installation is performed by a mechanic, millwright, or qualified technician using a 3 mm hex key or appropriately sized hex bit driver. Confirm the receiving threaded hole is M5x0.8 and free of debris before driving the fastener. Do not exceed the structural limits of the A2 stainless alloy in high-load shear applications where higher-grade fasteners may be required. Apply consistent, controlled torque to avoid thread galling, which is a known risk with stainless steel fasteners in metal-to-metal contact.
