Value Collection 41939 M8x1.25 Button Cap Screw 25mm 25-pack

Product Description

The VALUE COLLECTION 41939 is a fully threaded M8x1.25 button socket cap screw engineered for general mechanical assembly and structural fastening applications. The button head profile provides a low-profile clamping surface, and the hex socket drive accepts a 5mm hex key for installation in recessed or confined spaces. Manufactured from grade 10.9 alloy steel with a black oxide finish, this screw delivers high tensile strength and moderate corrosion resistance. At 25mm length under head, it is suited for medium-depth through-hole or tapped-hole assemblies. Each package contains 25 screws conforming to ISO 7380.

This fastener is appropriate for use in machine frames, brackets, equipment enclosures, and tooling fixtures where a low-profile head is required. The metric M8x1.25 thread standard and 4G/6G thread fit class make it compatible with standard metric tapped holes encountered in manufacturing, maintenance, and fabrication environments. Millwrights, maintenance technicians, and fabricators are the primary installers of this fastener type. The black oxide finish provides a clean, non-reflective appearance suited to exposed assemblies.

Key Features

• Low-profile button head for flush or near-flush installation in tight clearance areas
• 5mm hex socket drive for use with standard Allen keys and hex bit drivers
• Grade 10.9 alloy steel construction for high tensile and yield strength
• Black oxide finish provides mild corrosion resistance and a non-reflective surface
• Fully threaded shank for maximum thread engagement in shallow tapped holes
• Conforms to ISO 7380 fastener standard with 4G/6G thread fit class

Compatibility

Designed as a standard ISO 7380 metric button socket cap screw for use in any M8x1.25 right-hand threaded hole requiring a low-profile head fastener.

Installation Notes

Installation requires a 5mm hex key or hex socket bit driver. Ensure the mating tapped hole conforms to M8x1.25 metric thread specifications before installation. Verify torque requirements from the equipment manufacturer or applicable engineering standard for the specific assembly. Black oxide finish is not a substitute for plating in high-moisture or outdoor environments where additional corrosion protection may be required.
