Value Collection FHS1X0835-025BX M8x1.25 Flat Socket Cap Screw

Product Description

The VALUE COLLECTION FHS1X0835-025BX is a metric flat socket cap screw designed for flush or countersunk fastening applications in mechanical assemblies and structural connections. It features a 90-degree flat head with a 5 mm hex socket drive and is manufactured from 18-8 austenitic stainless steel to Grade A2, providing solid corrosion resistance in mildly corrosive environments. The screw follows DIN 7991 fastener standards, has a thread size of M8x1.25, and an overall length of 35 mm with partial threading. It is commonly installed by machinists, maintenance technicians, millwrights, and fabricators working on equipment where a low-profile or flush fastener head is required.

This screw is suited for use in metal fabrication, machine frames, brackets, enclosures, and equipment panels where a countersunk head keeps the fastener surface flush with or below the mating material. The partial threading allows for clamping force between joined components when the unthreaded shank spans the interface. Grade A2 stainless steel makes it appropriate for food processing equipment, marine ancillary hardware, and general industrial assemblies exposed to moisture or mild chemicals. This item is sold in a minimum order quantity of 25 pieces.

Key Features

• 90-degree flat head profile for flush or countersunk installations
• 5 mm hex socket drive for precise torque application with standard hex keys or Allen drivers
• M8x1.25 metric thread size conforming to DIN 7991 fastener standard
• Partially threaded shank for effective clamping across joined material layers
• 18-8 austenitic stainless steel at Grade A2 for corrosion resistance without plating
• Overall length of 35 mm measured as full overall length per metric convention

Compatibility

Designed as a DIN 7991 metric flat socket cap screw for any application requiring an M8x1.25 partially threaded countersunk fastener in 18-8 Grade A2 stainless steel.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a calibrated 5 mm hex key or Allen driver. Ensure the mating material is properly countersunk to 90 degrees before driving the fastener. Power down or de-energize any equipment before working on assemblies that involve live components. Do not exceed the rated mechanical limits of Grade A2 stainless steel in high-stress or high-temperature structural applications where higher-grade alloys may be required.
