Value Collection 535114PR M8x1.25 Button Socket Cap Screw

Product Description

The VALUE COLLECTION 535114PR is a fully threaded button socket cap screw engineered for applications requiring a low-profile head and high clamping strength. Manufactured from alloy steel at material grade 12.9, it delivers a hardness of 38 to 43 HRC and carries a black oxide finish for corrosion resistance and reduced light reflection. The M8x1.25 metric thread and 25mm length under head make it a practical choice for machine assembly, fixture work, and structural fastening where a standard hex head would interfere with clearance. Installation is driven by a 5mm hex socket key.

This screw suits a broad range of industrial and mechanical assembly environments. It is commonly used in machine tool fixtures, robotics frames, enclosures, and mechanical sub-assemblies where a button-head profile is required to keep fasteners flush or recessed within surrounding material. Its grade 12.9 rating positions it for high-load, vibration-prone applications. Licensed trade professionals, maintenance mechanics, and industrial assemblers are the primary installers of this fastener type.

Key Features

• Grade 12.9 alloy steel construction with 38 to 43 HRC hardness for high tensile strength
• Black oxide coating provides mild corrosion resistance and a non-reflective finish
• Button head profile keeps fastener low-profile in space-restricted assemblies
• 5mm hex socket drive for precise torque application
• Metric M8x1.25 thread, right-hand direction, thread fit class 4G and 6G
• Conforms to ANSI/ASME B18.3.4M and ISO 7380 fastener standards

Compatibility

Designed as an OEM-style replacement or standard-specification fastener for any application calling for an ISO 7380 button socket cap screw in M8x1.25 thread at 25mm length under head.

Installation Notes

Installation requires a 5mm hex socket key or driver bit rated for the applied torque load. Always verify thread engagement depth and mating material grade before final assembly, as grade 12.9 fasteners develop high clamp loads that can strip softer base materials. De-energize or depressurize any equipment before replacing fasteners in live mechanical assemblies. Minimum order quantity is 100 pieces per order.
