Value Collection 535120PR M8x1.25 Button Socket Cap Screw

Product Description

The VALUE COLLECTION 535120PR is a fully threaded button socket cap screw engineered for precision fastening in high-load mechanical assemblies. Manufactured from grade 12.9 alloy steel with a black oxide finish, this metric fastener delivers high tensile strength and moderate corrosion resistance in a low-profile button head profile. The M8x1.25 thread size and 40 mm length under head make it a standard choice for machine builders, maintenance mechanics, and fabricators working within metric fastener specifications. It conforms to ANSI/ASME B18.3.4M and ISO 7380 standards. A 5 mm hex socket drive provides solid torque transfer during installation with a standard hex key or Allen driver.

This button socket cap screw is used in general industrial, mechanical, and structural applications where a low-profile fastener head is required to clear adjacent components or mating surfaces. Common install scenarios include machine frames, brackets, panels, fixtures, and equipment assemblies where metric hardware is specified. The black oxide coating reduces galling and provides a clean appearance. This fastener is suited for use by maintenance technicians, machine shop professionals, and fabrication crews working with metric fastener standards.

Key Features

• Grade 12.9 alloy steel construction for high tensile and shear strength
• Black oxide finish for reduced galling and moderate corrosion resistance
• Button head profile keeps fastener below or flush with mating surfaces
• 5 mm hex socket drive compatible with standard Allen keys and hex bit drivers
• Conforms to ANSI/ASME B18.3.4M and ISO 7380 fastener standards
• Right-hand thread direction, M8x1.25 metric thread, thread fit class 4G and 6G

Compatibility

Designed as a standard metric replacement or new-install button socket cap screw for mechanical assemblies, machine frames, and fabricated structures requiring an ISO 7380 or ANSI/ASME B18.3.4M compliant M8x1.25 fastener.

Installation Notes

Installation is performed by maintenance mechanics or machine technicians using a 5 mm hex key or Allen driver. De-energize and lock out all equipment before servicing any fastened assembly per applicable OSHA lockout/tagout procedures. Apply thread-locking compound or hardened washers as required by the application design. Do not exceed the rated material grade torque specification for grade 12.9 M8 fasteners as defined by the equipment manufacturer or applicable engineering standard.
