Value Collection FHS1XX0850-025BX M8x1.25 Flat Socket Cap Screw

Product Description

The VALUE COLLECTION FHS1XX0850-025BX is a metric flat socket cap screw designed for flush or countersunk fastening applications. It features a 90-degree flat head with a 5 mm hex socket drive, an M8x1.25 thread, and an overall length of 50 mm with partial threading. Manufactured from 316 austenitic stainless steel to Grade A4, it provides strong resistance to corrosion in wet, marine, and chemical environments. This fastener meets DIN 7991 dimensional standards and is suited for mechanical assemblies, equipment fabrication, and structural connections where a low-profile head is required.

This screw is used in applications where the fastener head must sit flush with or below the mating surface. Typical installations include machine frames, enclosures, brackets, and assemblies exposed to moisture or corrosive conditions. Grade A4 stainless steel makes it appropriate for marine hardware, food-processing equipment, pool and chemical handling systems, and outdoor structural applications. The partial threading engages through standard clearance and tapped holes in metal, plastic, or composite materials. It is installed by mechanics, fabricators, millwrights, and maintenance technicians across industrial and commercial trades.

Key Features

• M8x1.25 metric thread with 50 mm overall length for deep countersunk installations
• 90-degree flat head profile allows flush or recessed seating in countersunk holes
• 5 mm hex socket drive for torque application with standard Allen keys or hex bits
• 316 austenitic stainless steel, Grade A4, for high corrosion resistance in wet and chemical environments
• Partially threaded shank per DIN 7991 for precise fit in through-hole and tapped assemblies
• Minimum order quantity of 25 pieces per order

Compatibility

Designed as an OEM-style replacement or direct-use fastener for metric countersunk socket cap screw applications conforming to DIN 7991, M8x1.25 thread class.

Installation Notes

Installation requires a 5 mm hex key or hex socket driver. Confirm the mating hole is countersunk to 90 degrees to match the head angle before fastening. De-energize and isolate any equipment before performing fastener replacement or assembly work. Avoid overtorquing stainless steel fasteners, as galling can occur — use appropriate anti-galling lubricant where recommended by assembly specifications.
