Value Collection FHS1XX1225-050BX M12x1.75 Flat Socket Cap Screw

Product Description

The VALUE COLLECTION FHS1XX1225-050BX is a metric flat socket cap screw designed for flush or countersunk fastening applications requiring corrosion-resistant hardware. It features an M12x1.75 thread size, a 25 mm overall length, and a fully threaded shank. The 90-degree flat head accepts an 8 mm hex socket drive. Manufactured from 316 austenitic stainless steel to Material Grade A4, this screw delivers strong resistance to corrosion, oxidation, and many chemical environments. It conforms to DIN 7991, the standard governing flat-head socket cap screws in metric fastener systems. Machinists, millwrights, marine technicians, and industrial maintenance professionals install this fastener where a low-profile, flush-seating cap screw is required.

This fastener is suited for general industrial, marine, food-processing, and chemical-processing environments where standard carbon steel hardware would corrode. The M12 coarse thread pitch and 25 mm overall length make it appropriate for medium-duty structural and mechanical assemblies that demand corrosion resistance combined with a countersunk, flush-mount profile. Its fully threaded shank maximizes thread engagement across the full length of the fastener, which is valuable in thinner or tapped-hole installations.

Key Features

• 90-degree flat head seats flush in countersunk holes for a low-profile installation
• 8 mm hex socket drive for precise torque application with standard Allen or hex-key tooling
• M12x1.75 coarse metric thread, fully threaded over the 25 mm overall length
• 316 austenitic stainless steel, Material Grade A4, for strong resistance to corrosion and oxidation
• Conforms to DIN 7991 metric fastener standard

Compatibility

Designed as an OEM-style and general-use replacement flat socket cap screw for metric M12x1.75 countersunk fastener applications conforming to DIN 7991.

Installation Notes

Installation is typically performed by machinists, millwrights, or mechanical technicians using an 8 mm hex key or socket driver. Ensure the mating hole is properly countersunk to a 90-degree included angle to achieve full bearing contact under the flat head. Verify thread engagement depth in the tapped hole meets the requirements of the applicable design standard before final torque. When installing stainless steel fasteners, apply an appropriate anti-seize compound to reduce the risk of galling on the threads.
