Value Collection FHS1X06100-010BX M6x1 Flat Socket Cap Screw

Product Description

The VALUE COLLECTION FHS1X06100-010BX is a metric flat socket cap screw engineered for flush or countersunk fastening applications. It features a 90-degree flat head profile driven by a 4.00 mm hex socket, keeping the fastener surface-flush when fully seated. The screw is manufactured from 18-8 austenitic Grade A2 stainless steel, providing solid corrosion resistance in wet, outdoor, and chemically active environments. The M6x1 thread designation indicates a 6 mm nominal diameter with a 1 mm thread pitch. At 100 mm overall length with partial threading, this fastener is suited for through-bolt assemblies where a grip zone is needed before the threaded section engages. Machinists, fabricators, and maintenance technicians are the primary installers.

This flat socket cap screw is appropriate for general industrial, mechanical, and structural assembly work where a countersunk socket drive is required and corrosion resistance is a priority. Typical applications include machine frames, enclosures, fixtures, brackets, and equipment panels that require a flush fastener surface. The 90-degree flat head seats cleanly into standard countersunk holes per DIN 7991 specifications. Partial threading makes it a practical choice for clamping two components together where a plain shank is needed in the clearance hole of the top piece.

Key Features

• 90-degree flat head profile for flush, countersunk installation
• 4.00 mm hex socket drive compatible with standard Allen keys and hex bit drivers
• 18-8 austenitic Grade A2 stainless steel construction for corrosion resistance
• M6x1 metric thread — 6 mm diameter, 1 mm pitch
• 100 mm overall length, partially threaded for clamping grip
• Conforms to DIN 7991 fastener standard

Compatibility

Designed as an OEM-style replacement or standard metric flat socket cap screw for applications requiring a DIN 7991-compliant M6x1 countersunk hex socket fastener in stainless steel.

Installation Notes

Installation is typically performed by machinists, fabricators, or maintenance technicians using a calibrated hex key or hex bit driver sized at 4.00 mm. Ensure the receiving hole is countersunk to a 90-degree included angle to achieve proper head seating. Do not overtighten stainless steel fasteners without lubrication, as galling can seize the threads permanently. Torque to the fastener specification appropriate for the material being clamped — do not use values not confirmed for this specific assembly.
