Value Collection FHS1X0650-025BX M6x1 Flat Socket Cap Screw 25pk

Product Description

The VALUE COLLECTION FHS1X0650-025BX is a metric flat socket cap screw designed for flush or countersunk fastening applications in metal, wood, and composite assemblies. It features a 90-degree flat head with a 4.00 mm hex socket drive and an M6x1 thread pitch. At 50.00 mm overall length with partial threading, this fastener seats cleanly into countersunk holes, leaving a low-profile surface. Manufactured from 18-8 austenitic stainless steel to Grade A2, it offers reliable corrosion resistance in moderate-exposure environments. This box ships in a minimum order quantity of 25 pieces. Installation requires a 4 mm hex key or Allen driver.

This screw is suited for precision mechanical assemblies, machine frames, enclosures, and structural components where a flush fastener surface is required. The DIN 7991 standard ensures dimensional consistency for use in metric-engineered applications across manufacturing, maintenance, and fabrication environments. It is commonly installed by machinists, millwrights, maintenance technicians, and fabricators working with metric hardware specifications. The partial threading provides positive clamping force on through-bolted joints and threaded inserts alike.

Key Features

• 90-degree flat head profile allows countersunk, flush-mount installation
• 4.00 mm hex socket drive for standard Allen key or hex bit installation
• M6x1 metric thread size per DIN 7991 standard
• 50.00 mm overall length with partial threading for secure joint clamping
• 18-8 austenitic stainless steel, Grade A2, for corrosion resistance in general-use environments
• Sold in a box quantity of 25 pieces per minimum order

Compatibility

Designed as a DIN 7991-compliant M6x1 flat socket cap screw suitable for metric-threaded assemblies requiring a countersunk hex socket fastener.

Installation Notes

Installation requires a 4 mm hex key or hex bit driver. Countersink the receiving hole to a 90-degree angle to match the flat head geometry before driving the fastener. Ensure the mating thread or insert is clean and free of debris before assembly. When working with stainless steel fasteners, apply an anti-seize compound to the threads to prevent galling during torque-down.
