Value Collection FHS1X0545-025BX Flat Socket Cap Screw M5x0.8

Product Description

The VALUE COLLECTION FHS1X0545-025BX is a metric flat socket cap screw designed for applications requiring a low-profile, flush-mounted fastening solution. Conforming to DIN 7991, this screw features a 90-degree flat head driven by a 3.00 mm hex socket. The M5x0.8 thread size and 45 mm overall length make it well suited for precision assemblies where head clearance is critical. Manufactured from 18-8 austenitic stainless steel to Grade A2, it offers reliable corrosion resistance in wet, chemical, or outdoor environments. The shank is partially threaded, allowing it to clamp mating components without thread engagement through the full grip length. Licensed trades and industrial maintenance technicians use this fastener in fabrication, equipment assembly, and structural panel work.

This screw is appropriate for metric fastening applications in residential, commercial, and light industrial settings. The Grade A2 stainless steel construction makes it a practical choice for marine-adjacent environments, food-grade equipment frames, HVAC panel assemblies, and similar installations where carbon steel hardware would be subject to surface oxidation. The DIN 7991 flat head profile allows the fastener to sit flush with or slightly below the surface of the mating material, eliminating protrusion in high-traffic or moving assemblies. Sold in a minimum order quantity of 25 pieces per order.

Key Features

• DIN 7991 standard flat socket cap screw with 90-degree countersunk head
• M5x0.8 metric thread with 45 mm overall length
• 3.00 mm hex socket drive for standard metric Allen keys or hex-bit drivers
• 18-8 austenitic stainless steel, Grade A2 — corrosion resistant in wet and mild chemical environments
• Partially threaded shank for effective clamping of stacked components
• Minimum order quantity of 25 pieces ensures job-lot availability

Compatibility

Designed as a standard DIN 7991 metric flat socket cap screw compatible with M5x0.8 threaded holes in any material where a countersunk hex-drive fastener is specified.

Installation Notes

Installation requires a 3.00 mm hex key or hex-bit driver; use of an incorrect driver size risks rounding the socket. Countersink the mating hole to the appropriate 90-degree angle before installation to achieve a proper flush seat. Torque to the value specified by the equipment manufacturer or applicable fastener standard for M5 Grade A2 stainless steel. When installing in stainless steel mating threads, apply an appropriate anti-seize compound to reduce the risk of galling.
