Value Collection FHS1X0870-010BX Flat Socket Cap Screw M8x1.25

Product Description

The VALUE COLLECTION FHS1X0870-010BX is a flat socket cap screw designed to deliver a low-profile, flush-seating fastener solution in metric applications. It features an M8x1.25 thread size and an overall length of 70 millimeters with partial threading along the shank. The 90-degree flat head seats flush or countersunk into mating surfaces, driven by a 5 mm hex socket. Constructed from 18-8 austenitic stainless steel at Material Grade A2, it provides solid corrosion resistance in wet, chemical, or outdoor environments. This fastener conforms to DIN 7991 standards. Machinists, millwrights, maintenance technicians, and fabricators typically specify this screw where a flush head profile is required alongside reliable corrosion performance.

This flat socket cap screw is suited for general industrial, mechanical, and structural assembly work where a countersunk, flush-mount fastener is needed. The partial threading design concentrates clamping force and allows for use in through-hole and clearance-hole configurations. Its A2 stainless steel composition makes it appropriate for use in food processing equipment, marine hardware, chemical handling assemblies, and outdoor structural connections where carbon steel fasteners would be unsuitable. This item is sold individually but carries a minimum order quantity of 10 units.

Key Features

• 90-degree flat head profile seats flush or countersunk into mating material surfaces
• M8x1.25 metric thread size with 70 mm overall length
• Partially threaded shank for improved clamping in through-hole assemblies
• 5 mm hex socket drive for precise torque application with standard Allen tooling
• 18-8 austenitic stainless steel at A2 grade for corrosion resistance in demanding environments
• Manufactured to DIN 7991 fastener standard for dimensional consistency

Compatibility

Designed as a metric DIN 7991 flat socket cap screw for use in any M8x1.25 threaded hole or countersunk application requiring a hex socket drive and flush head seating.

Installation Notes

Installation is typically performed by machinists, maintenance technicians, or fabricators using a 5 mm hex key or Allen driver. Ensure the mating countersink angle matches the 90-degree flat head geometry before driving. Do not overtighten stainless steel fasteners without proper lubrication, as galling of the threads can occur. Verify thread engagement depth and partial-thread shank clearance prior to final assembly.
