Value Collection FHS1XX0650-025BX M6x1 Flat Socket Cap Screw

Product Description

The VALUE COLLECTION FHS1XX0650-025BX is a metric flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. The 90-degree flat head sits flush with or below the mating surface when properly installed, eliminating protrusions that could interfere with moving parts or mating components. The hex socket drive accepts a 4.00 mm hex key for installation. Constructed from 316 austenitic stainless steel to Grade A4, this screw offers strong resistance to corrosion and is well suited for wet, marine, or chemically exposed environments. The M6x1 thread with 50 mm overall length and partial threading make it appropriate for fastening into threaded holes where a clamping grip along the shank is needed.

This screw is used in applications where a countersunk, low-profile fastener is required and corrosion resistance is a priority. Typical installations include marine hardware, food processing equipment, chemical processing assemblies, plumbing fixtures, and general fabrication work exposed to moisture or mild chemicals. It follows the DIN 7991 fastener standard and uses the metric thread system, making it compatible with standard metric tapped holes sized for M6x1 thread pitch. Sold in a minimum order quantity of 25 pieces per package.

Compatibility

Designed as a metric countersunk socket cap screw for use in standard M6x1 tapped holes per DIN 7991 specifications.

Installation Notes

Installation is performed using a 4.00 mm hex key or hex bit driver rated for the torque requirements of the application. Ensure the mating hole is countersunk to 90 degrees to match the flat head angle before driving the screw. Power down or de-energize any equipment before fastener replacement or assembly work. Do not cross-thread; start the screw by hand to confirm thread engagement before applying torque.
