Value Collection FHS1X0875-010BX M8x1.25 Flat Socket Cap Screw

Product Description

The VALUE COLLECTION FHS1X0875-010BX is a metric flat socket cap screw designed for flush or countersunk fastening applications where a low-profile head is required. It features a 90-degree flat head with a 5 mm hex socket drive and an M8x1.25 thread. The overall length is 75 mm with partial threading. Manufactured from 18-8 austenitic stainless steel to Grade A2, it offers corrosion resistance suitable for general industrial, marine-adjacent, and mechanical assembly environments. Licensed tradespeople, machinists, and maintenance technicians typically specify this fastener when countersunk socket drive access is needed.

This screw is used in applications requiring a flush seating surface, such as machine frames, fixture plates, enclosures, and equipment panels. The M8x1.25 metric thread and DIN 7991 standard make it a direct fit in metric-threaded assemblies across manufacturing, mechanical, and industrial maintenance settings. Partial threading provides clamping force between joined materials. The hex socket drive requires a 5 mm hex key for installation and removal.

Key Features

• 90-degree flat head seats flush in countersunk holes for low-profile clearance
• 5 mm hex socket drive for precise torque application with standard hex keys
• M8x1.25 metric thread conforms to DIN 7991 fastener standard
• Partially threaded shank provides clamping grip in two-material joints
• 18-8 austenitic stainless steel, Grade A2, resists corrosion in wet and chemical-adjacent environments
• 75 mm overall length suits medium-depth countersunk assemblies

Compatibility

Designed for use in metric-threaded assemblies requiring a DIN 7991-compliant M8x1.25 flat socket cap screw with a countersunk seating surface.

Installation Notes

Install using a 5 mm hex key or socket driver; ensure the mating hole is machined or drilled to a 90-degree countersink angle to achieve full head seating. Verify thread engagement depth meets design requirements before applying final torque. Stainless fasteners are susceptible to galling — apply a compatible anti-seize compound when torquing into stainless or aluminum tapped holes. Follow applicable mechanical or structural codes for fastener torque specifications based on joint requirements.
