Value Collection 531288PR M12x1.75 50mm Low Cap Screw

Product Description

The VALUE COLLECTION 531288PR is a metric low socket cap screw designed for applications where a reduced head height is required without sacrificing clamping strength. Manufactured from alloy steel with a black oxide finish, this fastener meets SIP 147 standards and carries a material grade of 10.9, indicating high tensile strength suitable for demanding mechanical assemblies. The partially threaded shank provides a smooth bearing surface along the grip length, which is measured from under the head. Driven with an 8 mm hex key, the screw is well-suited for machine building, tooling fixtures, and industrial equipment maintenance performed by millwrights, machinists, and maintenance technicians.

This fastener is intended for metric threaded applications requiring an M12x1.75 thread profile with a 50 mm length under the head. The low socket cap head profile is useful in recessed or space-constrained installations where a standard socket cap head would interfere with adjacent components or mating surfaces. It is commonly used in metal fabrication, machinery assembly, and structural bolted joints where controlled torque and high clamping load are required.

Key Features

• M12x1.75 metric thread with 50 mm length under head
• Low socket cap head for reduced-clearance installations
• Alloy steel construction with 10.9 material grade for high tensile strength
• Black oxide finish provides mild corrosion resistance and reduced light reflection
• Partially threaded shank for improved shear load performance
• 8 mm hex socket drive; conforms to SIP 147 fastener standard

Compatibility

Designed for use in metric threaded assemblies requiring an M12x1.75 thread form per the SIP 147 fastener standard. Suitable for steel, cast iron, and aluminum tapped holes meeting M12 metric specifications.

Installation Notes

Installation should be performed by a qualified mechanic or machinist using a calibrated 8 mm hex key or hex bit driver. Verify that the tapped hole thread profile and depth are compatible with M12x1.75 before installation. Apply appropriate thread lubricant or fastener compound as required by the assembly specification to achieve accurate torque-to-clamp-load conversion. Inspect threads and seating surfaces for damage before torquing to final value.
