Value Collection FHS1X0680-010BX M6x1 Flat Socket Cap Screw

Product Description

The VALUE COLLECTION FHS1X0680-010BX is a metric flat socket cap screw manufactured from 18-8 austenitic stainless steel, Grade A2. It features a 90-degree flat head with a hex socket drive, requiring a 4 mm hex key for installation. The M6x1 thread size and 80 mm body length make it a standard metric fastener suited to mechanical assemblies, machine construction, and structural applications where a flush or countersunk head profile is required. The partial threading leaves a smooth shank section near the head, which improves shear resistance in close-tolerance bores. This screw conforms to DIN 7991 and is sold in multiples of 10 units.

This fastener is used in applications where the head must sit flush with or below the surface of the mating material. Typical installations include machine frames, panel assemblies, equipment housings, and fixtures in industrial or commercial environments. The 18-8 stainless steel construction provides corrosion resistance suitable for both indoor and moderately wet service conditions. Mechanical contractors, millwrights, maintenance technicians, and fabricators commonly specify this screw type when a clean, low-profile fastening solution is needed and access for a hex key is available.

Key Features

• 90-degree flat head countersunk profile for flush or below-surface installation
• Hex socket drive accommodates a 4 mm hex key for high-torque engagement in tight spaces
• M6x1 metric thread per DIN 7991 standard for consistent dimensional compliance
• 18-8 austenitic stainless steel, Grade A2, provides corrosion resistance in moderate service environments
• Partial threading preserves a smooth shank for improved shear load performance
• Sold in minimum order quantity of 10 units

Compatibility

Designed as a DIN 7991-compliant metric flat socket cap screw. Compatible with M6x1-threaded holes in metal, plastic, and composite assemblies where a countersunk hex-socket fastener is specified.

Installation Notes

Installation requires a 4 mm hex key or hex socket bit. Countersink the mating material to the appropriate 90-degree angle before driving the screw to achieve a proper flush fit. De-energize or lock out any equipment before performing fastener installation or replacement on live machinery. Apply an appropriate thread lubricant or anti-seize compound when assembling stainless-to-stainless connections to reduce the risk of galling.
