The VALUE COLLECTION FHS1X0690-010BX is a metric flat socket cap screw designed for applications requiring a flush or countersunk fastening profile. It features a 90-degree flat head with a 4 millimeter hex socket drive and is partially threaded along its 90 millimeter overall length. The fastener is manufactured from 18-8 austenitic stainless steel to Grade A2, providing solid corrosion resistance in wet, outdoor, or mildly chemical environments. Machinists, fabricators, and maintenance technicians use this screw where a low-profile head is required and exposed fastener height must be minimized.
This screw is suited for use in general mechanical assemblies, equipment panels, enclosures, and structural components where metric fasteners are specified. The M6x1 thread size and 90 millimeter length make it applicable across a wide range of light industrial and commercial fabrication tasks. The partial threading allows for shoulder-grip clamping in thicker material stacks, a common requirement in precision assembly work. Sold in multiples of 10, this fastener is appropriate for shop stock, repair kits, or batch assembly operations.
Designed as an OEM-style replacement or stock fastener for metric M6x1 threaded assemblies requiring a countersunk flat socket cap screw per DIN 7991.
Installation is typically performed by machinists, assemblers, or maintenance technicians using a 4 millimeter hex key or hex socket bit. Ensure the mating countersunk hole is machined or drilled to the correct 90-degree angle to achieve full head seating. Do not overtighten stainless steel fasteners, as galling can occur; apply an appropriate anti-seize compound when installing into stainless or aluminum tapped holes. Verify thread engagement depth meets design requirements before final torque.
