Value Collection 41938 M8x1.25 Button Socket Cap Screw

Product Description

The VALUE COLLECTION 41938 is a fully threaded M8x1.25 button socket cap screw designed for metric fastening applications requiring a low-profile head. Manufactured from Grade 10.9 alloy steel with a black oxide finish, this screw delivers high tensile strength and moderate corrosion resistance. The 5 mm hex socket drive accepts a standard hex key or Allen-type bit. The button head style distributes clamping load over a wider bearing surface compared to a standard socket head, making it well-suited for applications where clearance above the joint is limited. Sold in a minimum order quantity of 25 pieces per package.

This fastener is used across a broad range of trade and industrial applications including machinery assembly, equipment frames, enclosures, brackets, and structural fixturing where metric thread standards are specified. The ISO 7380 fastener standard governs its dimensional characteristics. Thread fit class 4G and 6G tolerances make it compatible with standard metric tapped holes. Right-hand thread direction is standard. Applicable in both shop and field assembly contexts wherever a low-profile metric socket cap screw is called out on a drawing or spec sheet.

Key Features

• Grade 10.9 alloy steel construction for high tensile strength in demanding fastening applications
• Black oxide finish provides a uniform dark appearance and mild corrosion resistance
• Button head profile offers a wider bearing surface and lower stack height than standard socket head cap screws
• 5 mm hex socket drive accepts standard hex keys and hex bit drivers
• Fully threaded shank along the 20 mm length under head for maximum thread engagement
• Conforms to ISO 7380 fastener standard with 4G and 6G thread fit class tolerances

Compatibility

Designed as an OEM-style metric fastener compatible with standard M8x1.25 right-hand threaded tapped holes conforming to metric thread standards.

Installation Notes

Installation is typically performed by machinists, millwrights, or mechanical technicians using a 5 mm hex key or hex socket bit. Verify that the mating tapped hole is clean and free of debris before installation. Do not exceed the rated torque for Grade 10.9 M8 fasteners as specified by the equipment manufacturer or applicable engineering standards. Black oxide finish is not a substitute for a dedicated corrosion-protection coating in high-moisture or outdoor environments.
