Value Collection 535110P M8x1.25 Button Cap Screw 16mm

Product Description

The VALUE COLLECTION 535110P is a fully threaded M8x1.25 button socket cap screw designed for applications requiring a low-profile head and high-strength fastening. Manufactured from Grade 12.9 alloy steel, this metric fastener delivers a hardness rating of 38 to 43 HRC, making it suitable for demanding mechanical assemblies. The black oxide finish provides moderate corrosion resistance and reduces light reflection in finished assemblies. The hex socket drive accepts a 5 mm hex key for installation and removal. Machinists, maintenance technicians, and mechanical assemblers commonly use this fastener type in equipment builds and machine frame work.

This screw is well suited for use in industrial machinery, tooling fixtures, and mechanical sub-assemblies where a button head profile is needed to clear adjacent components or mating surfaces. The 16 mm length under head and M8x1.25 thread pitch conform to ANSI/ASME B18.3.4M and ISO 7380 standards, making this fastener compatible with standard metric tapped holes in steel, aluminum, and cast components. Thread fit classes 4G and 6G allow for typical production tolerances. This fastener is sold individually but carries a minimum order quantity of 100 units.

Key Features

• Grade 12.9 alloy steel construction with 38 to 43 HRC hardness for high-strength fastening
• Button head profile provides low-profile seating and clearance in tight assemblies
• 5 mm hex socket drive for use with standard hex keys and socket bits
• Black oxide finish for moderate corrosion resistance and clean appearance
• Fully threaded along the 16 mm under-head length for maximum thread engagement
• Conforms to ANSI/ASME B18.3.4M and ISO 7380 standards

Compatibility

Designed as a metric replacement or production fastener for standard M8x1.25 tapped holes per ANSI/ASME B18.3.4M and ISO 7380. Thread fit classes 4G and 6G cover typical production and commercial tolerance applications in steel and aluminum assemblies.

Installation Notes

Installation is performed with a 5 mm hex key or matching socket bit. Ensure the receiving tapped hole is clean and free of debris before driving the screw. De-energize and lock out any equipment before servicing fasteners in live mechanical assemblies. Do not exceed the torque capacity appropriate for Grade 12.9 M8 fasteners as specified by the equipment manufacturer or applicable engineering standards.
