Value Collection 535118PR M8x1.25 Button Cap Screw Alloy Steel

Product Description

The VALUE COLLECTION 535118PR is a fully threaded button socket cap screw designed for applications requiring a low-profile head with high clamping strength. Built from alloy steel at material grade 12.9, this fastener delivers a tensile strength appropriate for demanding mechanical assemblies. The black oxide finish provides mild corrosion resistance and reduces light reflection in finished assemblies. With an M8x1.25 thread and 35mm length under head, it accepts a 5mm hex socket drive. Maintenance technicians and mechanical assemblers working on equipment, fixtures, and fabricated frames are the primary installers.

This fastener suits a wide range of industrial and mechanical applications where a button head profile is needed to clear adjacent components or provide a flush-style appearance. The fully threaded shank and metric M8x1.25 thread form make it compatible with standard metric tapped holes and hardware in machinery, enclosures, panels, and structural assemblies. It conforms to ANSI/ASME B18.3.4M and ISO 7380 standards, making it a direct-fit option in metric fastener specifications.

Key Features

• Button head, low-profile design with 5mm hex socket drive
• Alloy steel construction at grade 12.9 for high tensile load capacity
• Black oxide coating for mild corrosion resistance and reduced reflectivity
• Fully threaded shank for maximum thread engagement in thin materials
• Meets ANSI/ASME B18.3.4M and ISO 7380 fastener standards
• Right-hand thread direction, metric thread standard

Compatibility

Designed as an OEM-style replacement or direct metric fastener for applications requiring an M8x1.25 button socket cap screw conforming to ISO 7380 and ANSI/ASME B18.3.4M standards.

Installation Notes

Installation requires a 5mm hex socket or ball-end hex key. Ensure the tapped hole thread class is compatible with the 4G or 6G thread fit class of this fastener before driving. Apply appropriate thread-locking compound or torque procedures per the equipment manufacturer's specifications. Do not overtighten, as alloy steel fasteners at grade 12.9 are susceptible to hydrogen embrittlement if improperly handled during installation.
