Value Collection FHS1X0865-010BX M8x1.25 Flat Socket Cap Screw

Product Description

The VALUE COLLECTION FHS1X0865-010BX is a metric flat socket cap screw designed for applications where a flush or countersunk fastener profile is required. It features a 90-degree flat head with a 5 mm hex socket drive and a partially threaded shank. Thread size is M8x1.25 with an overall length of 65 mm. The fastener is manufactured from 18-8 austenitic stainless steel to Grade A2, providing corrosion resistance in general industrial, mechanical, and light structural assemblies. Maintenance technicians, millwrights, and equipment fabricators use this type of fastener when a standard hex-head or button-head profile is not suitable for the application.

This flat socket cap screw is suited for use in mechanical assemblies, machine frames, enclosures, and fixtures where the fastener head must sit flush with or below the mating surface. The partial threading allows the unthreaded portion of the shank to act as a locating feature in close-tolerance bores. Conforming to DIN 7991, this fastener fits into standard countersunk hole patterns designed for that specification. Grade A2 stainless construction makes it appropriate for moderately corrosive environments including food processing equipment, marine adjacent hardware, and chemical handling fixtures.

Key Features

• 90-degree flat head profile allows flush or countersunk installation in DIN 7991-compatible hole patterns
• 5 mm hex socket drive accepts standard metric hex keys and socket bits
• M8x1.25 thread size with 65 mm overall length
• Partially threaded shank provides shank-to-bore location in precision assemblies
• 18-8 austenitic stainless steel, Grade A2, for corrosion resistance in industrial and light-marine environments
• Conforms to DIN 7991 fastener standard

Compatibility

Designed as a direct-fit replacement or standard-stock fastener for any assembly requiring a DIN 7991 M8x1.25 flat socket cap screw with a 65 mm overall length in 18-8 Grade A2 stainless steel.

Installation Notes

Install using a calibrated 5 mm hex key or socket bit to avoid rounding the drive recess. Ensure the mating countersink is machined or drilled to the correct 90-degree angle per DIN 7991 specifications before installation. Apply an appropriate anti-seize compound when installing stainless fasteners into stainless or aluminum threaded holes to reduce the risk of galling. Do not exceed the rated torque for M8 Grade A2 stainless fasteners as specified in the relevant DIN or ISO standard for the assembly.
