Value Collection FHS1X12055-025BX M12x1.75 Flat Socket Cap Screw

Product Description

The VALUE COLLECTION FHS1X12055-025BX is a metric flat socket cap screw designed for flush or countersunk fastening applications where a low-profile head is required. It features a 90-degree flat head driven by an 8.00 mm hex socket and is manufactured from 18-8 austenitic stainless steel to Grade A2, providing corrosion resistance suitable for wet, chemical, or outdoor environments. The screw is M12x1.75 in thread size, 55.00 mm in overall length, and is partially threaded with a 30.00 mm thread length. It is installed by mechanical contractors, millwrights, and maintenance technicians working on equipment assemblies, structural fixtures, and machinery requiring a countersunk fastener profile.

This flat socket cap screw is used across a wide range of industrial, commercial, and mechanical applications where a flush-mount fastener is needed. The countersunk 90-degree head seats into chamfered holes, keeping surfaces smooth and interference-free. Typical install scenarios include equipment housings, machine frames, brackets, and structural assemblies. The stainless steel construction makes it well suited for food processing, marine, chemical, and HVAC equipment environments where carbon steel fasteners would corrode. Sold with a minimum order quantity of 5 pieces per purchase.

• Plain finish with no coating for dimensional accuracy and material compatibility

Compatibility

Designed as an OEM-style metric flat socket cap screw for use in any application requiring an M12x1.75 countersunk hex socket fastener conforming to DIN 7991.

Installation Notes

Installation is performed by qualified mechanical or maintenance technicians using an appropriately sized hex key or socket driver. Always de-energize and lock out equipment before fastener work on live machinery. Drill and countersink the mating hole to the correct 90-degree angle to achieve full head seating. Do not over-torque stainless steel fasteners, as galling can occur — use an appropriate anti-galling lubricant on the threads if required by the application.
