Value Collection 535190PR M12x1.75 Button Socket Cap Screw

Product Description

The VALUE COLLECTION 535190PR is a fully threaded button socket cap screw engineered for metric fastening applications requiring a low-profile head and high clamping strength. Manufactured from alloy steel at material grade 12.9, this fastener delivers a hardness of 38-43 HRC, making it suitable for high-stress assemblies where tensile strength and shear resistance are critical. The black oxide coating provides a degree of corrosion resistance and a clean, finished appearance. Driven by an 8 mm hex socket, the button head design keeps the fastener profile low while maintaining a secure drive engagement for installation and removal.

This screw is used across mechanical, industrial, and fabrication applications where metric hardware is specified. With an M12x1.75 thread and a 16 mm length under head, it fits a range of assembly configurations in equipment manufacturing, structural fixtures, and component mounting. The right-hand thread direction follows standard metric fastening convention. Installation is typically performed by machinists, millwrights, or maintenance technicians working to metric design specifications.

Key Features

• M12x1.75 fully threaded metric configuration with right-hand thread direction
• Material grade 12.9 alloy steel with 38-43 HRC hardness rating
• Button head, hex socket drive type using an 8 mm key
• 16 mm length under head for consistent stack-up clearance
• Black oxide finish for surface protection and reduced reflectivity
• Meets ANSI/ASME B18.3.4M and ISO 7380 fastener standards

Compatibility

Designed as a metric replacement or standard-fit button socket cap screw for assemblies requiring an M12x1.75 thread with thread fit class 4G or 6G per ISO 7380 and ANSI/ASME B18.3.4M specifications.

Installation Notes

Installation requires an 8 mm hex socket key or Allen wrench. Power down and de-energize any equipment before servicing fastened assemblies. Apply thread engagement best practices per the governing design specification and torque to values called out in the applicable engineering drawing, as no torque value is included with this listing. Do not mix metric and inch-standard fasteners in the same joint.
