Value Collection FHS1XX0520-050BX M5x0.8 Flat Socket Cap Screw

Product Description

The VALUE COLLECTION FHS1XX0520-050BX is a metric flat socket cap screw conforming to DIN 7991, manufactured from 316 austenitic stainless steel classified as Grade A4. The fastener features a 90-degree countersunk flat head driven by a 3.00 mm hex socket (Allen key) and carries an M5x0.8 thread designation with an overall length of 20.00 mm. The shank is partially threaded. Grade A4 stainless steel provides strong resistance to corrosion in wet, marine, and chemically aggressive environments, making this screw a dependable choice for critical fastening applications where galvanic compatibility and long-term integrity are required. Sold in a minimum order quantity of 50 pieces.

This screw is suited for applications where the fastener head must sit flush with or below a mating surface, eliminating protrusion. Typical uses include panel assembly, enclosure fabrication, food-service equipment, marine hardware, and industrial machinery where metric fasteners and a clean finished appearance are specified. The M5 thread size and DIN 7991 standard make this screw interchangeable with other DIN 7991 compliant hardware across metric assemblies in both light commercial and industrial settings. Installers working under ISO or metric-based engineering specifications will find this fastener dimensionally consistent with standard M5 countersunk socket head designs.

Key Features

• DIN 7991 compliant flat countersunk head for flush or sub-flush installation
• 316 stainless steel, Grade A4 for superior corrosion resistance in harsh and marine environments
• 3.00 mm hex socket drive for precise torque application with standard Allen wrenches or hex bits
• M5x0.8 metric thread with 20.00 mm overall length, partially threaded shank
• 90-degree flat head angle seats cleanly in standard countersunk holes
• Minimum order quantity of 50 pieces ensures job-site supply continuity

Compatibility

Designed as a DIN 7991 standard metric flat socket cap screw in M5x0.8 thread size, compatible with any countersunk metric hole pattern dimensioned for M5 DIN 7991 fasteners across industrial, marine, and commercial assemblies.

Installation Notes

Installation is performed with a 3.00 mm hex key or matching hex bit driver. Ensure the receiving material has a properly dimensioned 90-degree countersunk bore to fully seat the fastener head flush. When installing into stainless steel tapped holes, apply an anti-galling lubricant to reduce the risk of thread seizure, which is common with austenitic stainless fasteners. Torque to the value specified by the assembly engineer or applicable equipment documentation, as no torque value is supplied with this fastener alone.
