Value Collection 41937 M8x1.25 Button Cap Screw 16mm

Product Description

The VALUE COLLECTION 41937 is a fully threaded M8x1.25 button socket cap screw designed for mechanical assemblies requiring a low-profile, high-strength fastener. Manufactured from Grade 10.9 alloy steel with a black oxide finish, this screw delivers tensile strength suitable for demanding industrial and mechanical applications. The hex socket drive accepts a 5 mm hex key for installation. At 16 mm length under the head, it fits a range of standard metric fastening applications. The black oxide finish provides moderate corrosion resistance and reduces light glare in exposed assemblies. This fastener conforms to ISO 7380, ensuring dimensional consistency and interchangeability with other metric hardware.

This screw is suited for use in machinery, equipment frames, tooling fixtures, and fabricated assemblies where a flush or near-flush fastener profile is preferred over a traditional hex cap screw. The button head style distributes clamping load over a wider bearing surface than a flat head, making it a practical choice when working with thinner or softer substrate materials. Machinists, millwrights, fabricators, and maintenance technicians commonly install these in production and field-service environments. The right-hand thread direction and 4G/6G thread fit class ensure reliable engagement with standard metric tapped holes.

Key Features

• Grade 10.9 alloy steel construction for high tensile strength
• Black oxide finish for moderate corrosion resistance and low reflectivity
• Button head profile provides a low-profile, wide-bearing-surface installation
• 5 mm hex socket drive for standard hex key installation
• Conforms to ISO 7380 for dimensional consistency
• Right-hand thread, 4G/6G fit class for standard metric tapped holes

Compatibility

Designed as a standard metric replacement or stocking fastener for M8x1.25 tapped holes conforming to ISO 7380 button socket cap screw specifications.

Installation Notes

Install using a 5 mm hex key or socket driver; ensure the tapped hole depth and thread condition are verified before installation. Torque to the specification required by the assembly drawing or applicable engineering standard for Grade 10.9 metric fasteners. De-energize or de-pressurize any system before servicing components secured by these fasteners. Do not reuse fasteners that show signs of thread damage, galling, or corrosion.
