Value Collection FHS1X1250-025BX M12x1.75 Flat Socket Cap Screw

Product Description

The VALUE COLLECTION FHS1X1250-025BX is a metric flat socket cap screw designed for flush or countersunk fastening applications where a low-profile head is required. Built to DIN 7991 standards, this screw features a 90-degree flat head with an 8.00 mm hex socket drive, allowing installation with a standard hex key. The fastener is manufactured from 18-8 austenitic stainless steel, Grade A2, providing solid corrosion resistance in moderate service environments. The M12x1.75 thread size with partial threading along a 50 mm overall length suits structural assembly work where thread engagement depth and shank clearance are both critical.

This screw is suited for mechanical, industrial, and fabrication applications where a countersunk socket head is preferred over a raised cap style. Partial threading makes it effective in joints where grip-length alignment is necessary. Common installation scenarios include machine frames, equipment enclosures, brackets, and assemblies requiring flush or recessed fastening. The stainless steel construction makes it appropriate for outdoor, wet, or corrosion-prone environments where zinc-plated carbon steel fasteners would degrade. It is sold individually with a minimum order quantity of 5 pieces.

Key Features

• 90-degree flat head profile for flush or countersunk installation
• 8.00 mm hex socket drive for standard hex key installation
• M12x1.75 metric thread, conforming to DIN 7991 fastener standard
• Partially threaded shank for grip-length control in structural joints
• 18-8 austenitic stainless steel, Grade A2, for corrosion resistance
• 50 mm overall length measured end to end

Compatibility

Designed as a DIN 7991 metric flat socket cap screw for use in applications requiring an M12x1.75 thread size and countersunk hex socket fastening.

Installation Notes

Installation is performed with a calibrated 8.00 mm hex key or socket driver. The mating countersink in the workpiece should conform to the 90-degree included angle to ensure full head seating without rocking. Verify thread engagement depth meets structural requirements before torquing, as partial threading limits the engaged zone. Do not mix stainless fasteners with dissimilar metals in assemblies where galvanic corrosion is a concern.
