Value Collection FHS1X0845-025BX M8x1.25 Flat Socket Cap Screw

Product Description

The VALUE COLLECTION FHS1X0845-025BX is a metric flat socket cap screw designed for flush or countersunk fastening applications. It features an M8x1.25 thread size, a 45 mm overall length, and a 90-degree flat head driven by a 5 mm hex socket. Constructed from 18-8 austenitic stainless steel meeting Grade A2 requirements, this screw provides solid corrosion resistance in wet, marine, or chemical-adjacent environments. The shank is partially threaded, which allows for controlled clamping force in bolted joints. Machinists, fabricators, maintenance technicians, and industrial installers commonly specify this fastener where a low-profile head is required to sit flush with or below the mating surface.

This flat socket cap screw is suited for metal fabrication, machine assembly, equipment maintenance, and structural fastening tasks where a recessed or countersunk head profile is required. The M8x1.25 metric thread and DIN 7991 standard make it interchangeable with other DIN 7991-compliant hardware in metric assemblies. Sold in a minimum order quantity of 25 pieces, this screw is appropriate for shop stock, production runs, or service kits where multiple fasteners of the same specification are needed.

Key Features

• 90-degree flat head profile seats flush in countersunk holes for a low-profile finish
• 5 mm hex socket drive for use with standard hex keys or socket bits
• M8x1.25 metric thread conforms to DIN 7991 fastener standard
• 18-8 austenitic stainless steel, Grade A2, for corrosion resistance in demanding environments
• Partially threaded shank for improved clamping and grip in bolted joints
• Minimum order quantity of 25 units supports production and maintenance stocking needs

Compatibility

Designed as a DIN 7991-compliant metric fastener for use in any application requiring an M8x1.25 countersunk hex socket screw with a 45 mm overall length and Grade A2 stainless steel construction.

Installation Notes

Installation is typically performed by machinists, millwrights, or maintenance technicians using a 5 mm hex key or hex socket bit. Countersink the mating material to the appropriate 90-degree angle before seating the screw to ensure full head contact and flush seating. Apply thread-locking compound or anti-seize as required by the assembly specification. Do not exceed the rated torque for the Grade A2 material grade as defined by the applicable fastener standard.
