Value Collection FHS1X1220-050BX M12x1.75 Flat Socket Cap Screw

Product Description

The VALUE COLLECTION FHS1X1220-050BX is a metric flat socket cap screw designed for flush or countersunk fastening applications. It features an M12x1.75 thread size, a 20mm overall length, and a fully threaded shank. The 90-degree flat head seats flush with the mating surface when installed in a properly countersunk hole. The 8mm hex socket drive accepts a standard hex key for installation and removal. Constructed from 18-8 austenitic stainless steel to Grade A2 per DIN 7991, this screw provides corrosion resistance suitable for general industrial, marine-adjacent, and outdoor service environments where mild to moderate chemical exposure is expected.

This screw is used in applications where a low-profile, flush fastener is required and a countersunk seat is already machined or formed into the base material. Typical applications include machinery frames, enclosures, brackets, and structural assemblies that require a smooth finished surface. It is appropriate for use by maintenance technicians, fabricators, millwrights, and mechanical contractors working with metric-standard assemblies. The fully threaded configuration maximizes thread engagement across the full 20mm length, which is useful in thin-material or through-bolt applications.

Key Features

• M12x1.75 metric thread size with fully threaded 20mm overall length
• 90-degree flat head profile seats flush in countersunk holes
• 8mm hex socket drive for standard hex key or socket tooling
• 18-8 austenitic stainless steel, Material Grade A2 per DIN 7991
• Metric thread standard with fully threaded shank for maximum engagement

Compatibility

Designed as a DIN 7991 standard metric flat socket cap screw for use in any M12x1.75 countersunk threaded application requiring Grade A2 stainless steel construction.

Installation Notes

Installation requires a properly countersunk hole sized for an M12 flat-head fastener to achieve full flush seating. Use a calibrated 8mm hex key or hex socket driver and follow applicable torque specifications from a recognized fastener standard for A2 stainless M12 hardware. Avoid over-torquing stainless steel fasteners, as galling can occur without proper anti-seize compound or lubrication. This fastener should be installed by qualified mechanical or maintenance personnel familiar with metric fastener standards.
